Wire and cable is very common in life, but many people do not know how to judge the quality of wire and cable, so how to judge the quality of wire and cable, below follow the Tianxing cable Xiaobian together to understand it.

Tianxing cable to teach you how to judge the quality of wire and cable

1, conductor DC resistance exceeds the standard. The copper conductor of the wire and cable should use high-purity electrolytic copper, so that the wire pulled out of the material is uniform and shiny. Some production enterprises use recycled copper for high profits, or cut corners to reduce the copper wire area, resulting in the conductor resistance of the wire seriously exceeded, the conductor carrying capacity of the wire is greatly reduced, and the conductor is overheated when used, affecting the service life of the wire and causing safety hazards.

2. The mechanical properties (tensile strength, elongation at break) of insulation and sheath materials are not qualified. The insulation and sheath materials of some wires and cables use recycled plastics, and their tensile strength and elongation at break cannot meet the requirements of use. This kind of cable is easy to break during the stress process, resulting in the live conductor exposed, resulting in short circuit and leakage discharge.

3, the high voltage cable insulation thermal extension project is not qualified. The thermal extension of insulation of individual products has a fusing phenomenon, which is easy to cause short circuit accidents at high temperature.
