Gold Prices Look to Real Rates as November FOMC Nears
Gold prices continue to tread water in familiar territory as expected, anchored by static real interest rates. Nominal yields are on the rise thanks to a hawkish turn in the Fed policy outlook, which has in turn tracked surging inflation expectations. Recently however, the rise in price growth bets has outpaced nominal rates, capping real yields.To get more news about ifx brokers, you can visit wikifx.com official website.
This seems to imply that markets expect the US central bank to fall behind the curve on curbing prices. Not surprisingly, that has kept gold afloat: traders have understandably reckoned that the 0% yield offered by bullion is a better store-of-value prospect than the negative return on cash.To get more news about ifx brokers minimum deposit, you can visit wikifx.com official website.
A rethink may be in order. Fed Funds futures imply that markets now price in 130 basis points in tightening through the end of 2024. Chair Jerome Powell and company projected a more spirited 175 basis points in hikes over the same period at last months FOMC conclave however.To get more news about ifx brokers review, you can visit wikifx.com official website.
With this in mind, the spotlight may shift to speculation about the November 3 gathering of the rate-setting committee in the days ahead. It is expected to formally introduce the process of tapering back QE asset purchases, setting the stage for rates to rise in the second half of 2022.
Traders pondering hawkish surprise risk might look to rebalance portfolios accordingly in the days ahead, pressuring bullion. Lasting follow-through seems unlikely for now however, with directional conviction in short supply before policymakers guidance can be gleaned and properly onboarded.
October‘s flash PMI surveys from the US, UK and Eurozone headline the data docket in the coming hours. Global economic news-flow has increasingly underperformed relative to forecasts recently, which may imply that analysts’ forecasts are rosier than reality supports and set the stage for downside surprises.
That might bode ill for gold if soft headline results come alongside indications of sticky price growth, which may in fact be amplifying the downshift in global output expansion since May. That mix might beckon swifter action from monetary authorities, pulling the metal lower within recent ranges.
Gold prices remain locked in familiar territory below the $1800/oz figure, though the bearish bias established from August 2020 remains intact. A break below support at 1750.78 may expose 1717.89 on route to the 2021 floor under $1700/oz. Resistance begins at 1808.16, followed by the range top at 1834.14. A daily close above that seems needed to make the case for upside follow-through.
The bending radius of the cable and its influence on the cable
1. What is the bending radius of the cable?
Cables must be actively or passively subjected to bending during the manufacturing, transportation, and installation and construction processes. When the cable is bent, the degree of bending is directly related to the bending radius of the cable.
1. The bending radius of the cable: Normally, we regard the bent cable as an arc, and the radius of the circle where the arc is located is the bending radius of the cable in the bending state.
2. The minimum bending radius of the cable: Due to the cable material and structural characteristics, the cable has a certain limit to withstand bending. The cable bending radius under this limit is the minimum bending radius of the cable.
2. The influence of too small cable bending radius on the cable
1. The effect of bending on the conductor
The cable conductor is made up of multiple single-core wires twisted at a certain pitch. The number of single wires and the pitch of the conductor determine the stability of the conductor during bending. Excessive bending will cause the conductor to become loose and loose. The protrusion directly affects the performance of the semi-conductive layer and insulating layer of the outer conductor.
2. The influence of cable bending on insulation
When the cable is bent with a certain bending radius, the insulation at the bend will undergo tensile deformation. When the bending exceeds the allowable minimum bending radius, it may cause insulation damage.
3. The effect of bending on metal shielding
Usually medium voltage cables are shielded by copper tape. When the cable is bent too much, the metal tape will wrinkle or curl, which will easily lead to insulation damage.

Precautions for installation of flame-retardant and fire-resistant cables
The characteristics of flame-retardant and fire-resistant cables: have the function of self-extinguishing, and can maintain the normal operation of the electrical circuit for a period of time under burning conditions. Therefore, the installation of flame-retardant and fire-resistant cables can effectively control major disasters caused by cable fire and prolonged combustion, thereby improving the fire protection level of electric lines. So, what matters should be paid attention to when installing flame-retardant and fire-resistant cables?
1. When laying cables in the same pipeline, it is not advisable to configure both flame-retardant and fire-resistant cables and ordinary non-fire-resistant cables.
2. When the number of cables to be installed is small, fire-resistant paint, tape, etc. can be added to the cables.
3. Places with high safety performance requirements, such as oil tank farms, important wooden structure public buildings, dense wire tunnels, hospitals, shopping malls, etc., need to be equipped with Class A flame-retardant and fire-resistant cables.
4. In industrial buildings, important circuits such as fire protection, alarm, emergency lighting, breaker operation DC power supply, and emergency shutdown power supply for generating sets and other important circuits need to be equipped with Class A flame-retardant and fire-resistant cables.
5. When too many cables are laid in the same pipeline, the cables need to be laid in the fire-resistant trough box.
6. In order to reduce the failure rate of wire connectors in fire accidents, the number of connectors should be reduced as much as possible during installation to ensure that the lines can work normally in a fire. If branch wiring is needed, fire-proof the joints should be done.
Classification of flame-retardant cables and flame-retardant grades A, B, and C
1. Definition and background
Due to the frequent occurrence of electrical fires, people have put forward higher requirements for the safety of wires and cables. Flame-retardant cables refer to cables that can spread the flame within a certain range and have the function of self-extinguishing when an electrical fire occurs.
The combustion of the cable is caused by the external heating to produce flammable gas. To realize the flame retardant of the cable, the three elements that cause the combustion must be suppressed: flammable gas, heat and oxygen. The traditional method is to add halogen-containing halides and metal oxides to the sheath material. This limits the spread of fire to a certain extent. However, because these materials contain halide, they release a large amount of smoke and hydrogen halide gas when burned. The visibility during fire is low, which brings great impact to the safety of personnel evacuation and fire fighting. obstacle. In recent years, with the continuous improvement of the level of science and technology, the flame retardant problem has been further developed from the halogen flame retardant in the past to the low halogen, halogen-free flame retardant.
2. Flame retardant grade
The determination of flame-retardant cable grade usually adopts the vertical burning test method of bundled wires and cables. The test divides wires and cables into flame-retardant A, B, and C three categories. That is to say, multiple wires or cables with a length of 3.5m (the total number is different due to the flame retardant category and the non-metallic materials contained in each meter of the wire and cable) are installed in bundles on the sample ladder and placed vertically in the test box In the medium, a gas burner with an intensity of 20.6kW is used to supply fire to the wires and cables vertically.
Class A and B flame-retardant wires and cables provide fire time for 40 minutes; Class C fire time for 20 minutes. After the test, if the carbonization height of the wire and cable does not exceed 2.5m, it will be passed. Specific grades of non-metallic materials per meter of wire and cable are as follows: A type 7 liters/meter; B type 3.5 liters/meter; C type 1.5 liters/meter.

2. The principle of circuit grouping: according to the circuit application in the home, carry out strong and weak current grouping, keep the distance between strong and weak current groups at 30-50 cm; group the circuits into living room, kitchen, bedroom and other applications according to the spatial layout of the family;
3. Circuit positioning principle: According to the placement of household electrical appliances, the layout of switches, the positioning of sockets, etc., carry out the planning and layout of the circuit.
4. Circuit grooving principle: The principle of horizontal and vertical grooving should be followed, and horizontal grooves should be opened as little as possible; if there are no more than 3 inflection points on the line, the shortest line should be planned and then grooved .
5. The principle of circuit buried pipe: circuit wiring generally adopts the method of concealed buried pipe. There are two types of wire pipes: cold-bent pipe and PVC pipe. Cold-bend pipes can be bent but difficult to break. It is recommended as the preferred choice for buried pipes.
Adhering to the five principles of circuit wiring in home decoration can enhance the safety of life electricity and provide convenience for future circuit maintenance and transformation.
6 skills that must be mastered when laying outdoor cables
The installation and construction of outdoor power cables is relatively difficult due to the complex terrain and numerous equipment and facilities in the urban area. In order to avoid problems such as cable abrasion, equipment damage, and personnel safety caused by construction, the following summarizes the 6 major techniques for laying outdoor power cables.
1. Before laying the cable, check whether the type and specification of the cable meet the design requirements: armored cables should be used for direct burial laying; unarmored cables should be used in cable trays, in cable shafts, overhead and pipe laying; Flame-retardant cables should be used in public places with higher fire protection requirements.
2. Check whether the cable reel and its protective layer are intact, and whether the two ends of the cable are damp.
3. According to the actual situation of the construction site, it is determined that the cable shall be laid in direct buried, vertical shaft, pipe-through or overhead laying methods.
4. When the power cable is buried directly underground, the distance from the ground should not be less than 0.7 meters, the distance between the pipeline and other parallel pipelines should be kept at least 2 meters, and the pipeline spacing should be more than 0.5 meters during cross laying.
5. The sequence of cable laying and the location of cable brackets should be planned as a whole before construction.
6.Pay attention to the abrasion of the cable at the bend during construction, and ensure that the cable has enough space for expansion and contraction.
Talking about the Causes and Preventive Measures of Electric Wire Fire
Reasons for the wire fire:
1. Short circuit: the phenomenon that the live wire and the live wire, and the live wire and the neutral wire are short-circuited on the electrical circuit. A short circuit can easily make the metal conductor instantaneously high temperature and cause the cable insulation material to catch fire.
2. Overload operation: Due to long-term overload operation, the operating temperature of the cable far exceeds the maximum allowable temperature during normal heating, which makes the insulation material of the cable aging and dry, so it is easy to break down and cause the wire to catch fire.
3. Excessive contact resistance: The contact resistance is too large due to poor contact at the junction of line and line, line and switch, and line and other electrical equipment. When strong current passes, it will also cause local heating and high temperature and cause line fire.
4. Leakage: The quality problems of the wire, such as poor insulation performance or friction or scratches in the laying of the wire, will cause the wire to leak. The electric spark and high temperature caused by the leakage will cause the wire to catch fire.
Prevention of wire fire:
1. Short-circuit prevention: Use safe fuse electrical switches and select flame-retardant cables with high safety factors. When a short-circuit fault occurs on the electrical circuit, the fuse will blow and cut off the current, and the flame-retardant cable has its own self-extinguishing performance, which greatly reduces the spread of fire.
2. Overload prevention: Do not pull wires randomly. When using high-power electrical appliances, consider the acceptable range of wires and cables. for
To prevent aging and breakdown of insulating materials during overload operation, it is recommended to use wires and cables with better aging resistance and lower eccentricity.
3. Prevention of excessive contact resistance: The electrical wiring must be installed in strict accordance with the electrical installation regulations. If necessary, please ask a professional electrician.
Set up the line.
4. Leakage prevention: choose wires and cables with good insulation material quality and strong bending resistance. In addition, regular
Check electrical wiring and equipment, etc.
The significance of measuring the insulation thickness of wires and cables
1.Standard value: The insulation thickness specified in the wire and cable product standard is based on the applicable voltage level of the product, the size of the conductor cross-section, the size of the current carrying capacity, the environmental conditions used, the electrical properties of the insulation material, the physical and mechanical properties, and the long-term consideration Many factors of the service life are determined through scientific calculations and long-term practical experience.
2.The significance of the measurement: if the measured value is smaller than the specified value, the wire and cable product will lose electrical insulation until it is broken down, causing personal and property damage; if it is greater than the specified value to a certain extent (exceeding the maximum value of the wire) Path), which brings a lot of troubles to users, until they can not be used, and increases costs for production enterprises.
How to Store Oxygen Tanks and the Best Way to Ship Them
Oxygen is the gas that gives life to every plant and animal on Earth, including humans, but it can be extremely dangerous when mishandled. Oxygen tanks, such as those used for oxyacetylene welding or for medical purposes, need to be handled by someone who knows how to store oxygen tanks and keep them protected.Get more news about Medical Oxygen Packing,you can vist our website!
The COVID-19 outbreak has led to an increase in demand for oxygen cylinders, and they continue to see wide use in industrial applications. If oxygen tanks are stored or handled at your business, read on—we’ll look at the key concepts for how to store oxygen tanks in a way that protects the safety of employees and the public. Then, we’ll examine how oxygen tanks can be transported safely and efficiently.
While oxygen itself is not flammable, it’s an excellent accelerant, meaning that it makes fires burn much hotter and more quickly. (Remember that the Fire Triangle lists oxygen as one of the three elements needed to start a fire.) When oxygen is released in an uncontrolled manner around open flames, it can create large fires that spread quickly and even cause explosions in some cases. Thus, oxygen tanks must be handled with the utmost care.
When one of these hazardous conditions is combined with the presence of an open flame, it can result in disaster, which is why it’s important to store and ship oxygen tanks safely.
The complete OSHA oxygen storage rules should be your go-to guide to storing compressed oxygen cylinders. It’s important to be familiar with the rules in their entirety, but here are some of the key regulations that must be followed:
In general, oxygen cylinders must be handled carefully so as to avoid knocks, bumps, and drops.
Oxygen cylinders must be stored in a designated area at least 20 feet away from fuel gas cylinders (such as acetylene) and/or other combustible materials. They may also be separated by a fireproof barrier at least five feet high.
Oxygen cylinders stored in an outside generator house must be separated from the generator by a fireproof barrier.
Oxygen cylinders must be clearly labeled using durable hazmat labels.
Oxygen cylinders must be kept well away from any source of heat such as a radiator.
Valves on oxygen cylinders must always be closed after use, and valves on empty cylinders must be kept closed.
Tools such as hammers, pry bars, and wrenches must not be used to open a stuck cylinder valve. Contact the cylinder supplier if a valve cannot be opened by hand.
Personnel other than hazmat certified employees of an authorized gas supplier should never mix gases inside a cylinder.
A gas detector should be used to track ambient oxygen levels and alert facility personnel if a spike in oxygen is detected.
Never tamper with the safety devices on an oxygen cylinder.
Facilities that store oxygen cylinders in large quantities must obey the NFPA 50 Standard for Bulk Oxygen at Consumer Sites.
Oxygen cylinders should be stored in proper cylinder storage receptacles.
