  • What kinds of factors affect the insulation resistance of wire and cable

    What kinds of factors affect the insulation resistance of wire and cable? The test of insulation resistance in wire and cable is mainly to measure the volume resistance of the insulation. The surface resistance is not calculated and measured. However, there are many factors that affect the insulation resistance of the cable. In practical application, the following four factors have a greater influence on its resistivity. Temperature affects wire and cable manufacturers

  • What do you know about the protective measures of wires and cables?

    What do you know about the protective measures of wires and cables? There are many types of wires and cables, and the quality of various cables on the market is uneven. The quality of the cables directly affects the quality of the project and the safety of consumers' lives and property. When purchasing wires and cables, you must understand the relevant situation in detail, at least how to choose and distinguish whether the cables are of high quality.

  • The reason for the yellowing of copper wires in wires and cables is as follows

    The reason for the yellowing of copper wires in wires and cables was originally that during such electricity production and daily life, accidents such as disconnection due to overheating of equipment connectors accounted for a part of the overall electrical accident, which brought a great threat to safe power supply. Take it lightly, let's take a look below. What is the reason for the yellowing of copper wires in wires and cables? & n

  • How to distinguish the flame retardant and fire resistance of cables

    How to distinguish the flame retardant and fire resistance of cables Some electrical construction personnel can't distinguish between the concept of flame retardant cables and fire resistance cables, and do not know much about the structure and characteristics of the two. Then, how to distinguish the flame retardant and fire resistance of cables? Flame retardant cable refers to: under the specified test conditions, the sample is burned, after the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residue is limited

  • What are the main processes of wire and cable production

    What are the main processes of wire and cable production? Wires and cables are produced through several major processes such as drawing, twisting, and covering. The more complicated the model specifications, the higher the repeatability. 1. Drawing In the process of metal pressing, the metal is forced through a mold (press wheel) under the action of external force, the cross-sectional area of the metal is compressed, and the required cross-sectional area shape and size are obtained.

  • How to determine Zhengzhou wire and cable breakpoint

    How to determine the Zhengzhou wire and cable breakpoint The following wire and cable manufacturers will talk about this problem for everyone, let's take a look below! When a breakpoint fault occurs in the cable or cable, it is difficult to intuitively determine the location of the breakpoint due to the outer insulation sheath. Here are some ways to quickly determine the breakpoints of wires and cables.

  • Do you know the cause and solution of overheating of wires and cables?

    Do you know the cause and solution of overheating of wires and cables? 1. The cable conductor resistance does not meet the requirements, causing the cable to generate heat during operation. 2. The improper selection of the cable causes the conductor cross section of the cable used to be too small, resulting in an overload phenomenon during operation. After a long time of use, the cable's heating and imbalance caused heat generation. Wire and cable manufacturers3.

  • How to solve the phenomenon of disconnection or disconnection of wires and cables

    How to solve the phenomenon of disconnected or broken wire and cable The wire and cable are used to transmit electrical energy, information, and wire products for electromagnetic energy conversion. One or more insulated cores, as well as the cladding, overall protective layer, and outer protective layer they may each have, and the cable may have additional uninsulated conductors. There may be some problems when we use wires and cables, such as disconnection.

  • What causes the wires and cables to overheat

    What causes wires and cables to overheat is what allows electricity to be transmitted through wires and cables, which provides us with power and brings us convenience. However, to a certain extent, it also brings security risks to our lives and property safety. For example, when a power cable passes a certain load current, it must be heated. As the load current increases, the temperature of the cable surface becomes higher.

  • How to distinguish the quality of wires and cables

    How to distinguish the quality of wire and cable 1. Measurement of capacitance and loss factor: When an AC voltage is added to the cable, a current flows. When the amplitude and frequency of the voltage are constant, the capacitance current is proportional to the capacitance of the cable (Cx) . For ultra-high voltage cables, the current of this capacitor may reach a value comparable to the rated current, which becomes important for cable capacity and transmission distance.
