RYJS wire and cable

RYJS means cross-linked polyethylene twisted pair connection flexible cable. R-cord, YJ-cross-linked polyethylene, S-twisted pair. R is the category and use code, YJ is the insulation type, and S is the characteristic. The common cable model is WDZN-BYJS.

Difference between wire and cable

The difference between wire and cable is that the size of wire is generally small and the structure is relatively simple, but sometimes the cable is also classified as a generalized wire. In a narrow sense, it is divided into wires and cables. In a broad sense, it is generally referred to as cables. Material difference: electric wire is used for conducting metal wire carrying current. There are solid, twisted or foil woven forms. Structure difference: The difference between power cable and ordinary wire is mainly due to the large size and complex structure of the cable. Difference in use: bare wires do not contain any insulation or protective layer. In addition to being used as a wire for transmitting electric energy and information, it can also be used for manufacturing components and connecting wires of motors and electrical appliances. In addition, there are all kinds of insulated wires suitable for special requirements, such as low-voltage wires for automobiles, high-voltage ignition wires for automobiles, electrical lead wires for motors, aviation wires, compensation wires, etc.

Wire and cable usage

Wire and cable are used to transmit, distribute electric energy or transmit electric signals. Cables can be divided into power cables, communication cables and control cables according to their purposes. The insulation distance between wires and cables is small, the floor space is small, the underground laying does not occupy the space above the ground, is not affected by the surrounding environmental pollution, the power transmission reliability is high, and the interference to personal safety and the surrounding environment is small. Therefore, cables are mostly used in densely populated areas, areas with dense power grids and places with heavy traffic. It plays an important role in the modernization drive.
