Wires and cables are now used in many places and have been widely used. Everyone will also want to know more about some aspects of it, so for a manufacturer specializing in the production of wires and cables, it is very necessary to introduce the knowledge points about wires and cables to everyone. The role […]

In the harsh winter, when laying and installing wire and cable, many construction workers will find that good quality wire and cable products usually make the wire somewhat hardened, and the insulating coating will also peel off and damage. Many construction workers believe that the wire and cable products themselves have quality problems, and cable

The reasons for cable failure can be divided into two categories, one is the failure of the cable insulation layer, including the aging and corrosion of the cable insulation layer. This kind of fault usually causes a circuit short circuit, burn, and so on. The other is cable breakage, generally caused by external mechanical forces,

Actually, High-quality cable is a vague concept. Generally speaking, it can meet the technical requirements of the circuit, and there is no excess performance, and the cable with qualified quality can be considered a high-quality cable. Determine the current carrying capacity requirements, ambient temperature, and humidity parameters of the laying line. The first step in

From the point of view of use, the high-quality cable should meet the following points:1. long service life. High-quality cables generally have a long service life or even the same life as the house, so there is no need to replace the cable during the life cycle of the house. Longjoy cable can supply cable

Ensure the construction quality, especially the production quality of cable end must be strict and meet the requirements. Monitor cable operation to avoid cable overload. Test wires and cables on time and deal with any abnormality in time. The cable trench should be kept dry, so as to avoid cable dampness, resulting in insulation performance

Cables are wires used to transmit and distribute electrical energy. In the power line, when passing a certain load current, the cable will heat up, with the increase of load current, the cable surface temperature will rise. What are the reasons for the heating of wires and cables in operation?1. The conductor resistance of the

If the cable is to be stored for a long time, the following considerations should be taken according to the location of the cable: 1. Under the eaves. The standard LAN cable can be used only when the cable is not directly exposed to sunlight or ultra-high temperature. It is recommended to use pipes. 2.
