Wire and cable problems how to identify the real and fake

1. Conductor DC resistance exceeds the standard. Wire and cable copper conductor should use high-purity electrolytic copper, so that the material pulled out of the silk uniform and shiny. Some manufacturers in order to obtain high profits using recycled copper, or cut corners to reduce the area of copper wire, resulting in a serious exceeding the conductor resistance of the wire, the conductor current-carrying capacity of the wire greatly reduced, the use of the conductor overheating, affecting the service life of the wire, resulting in a potential safety hazard. 2 insulation and sheathing materials, mechanical properties (tensile strength, elongation at break) indicators failed. Part of the wire and cable insulation and sheath materials using recycled plastic, its tensile strength and elongation at break can not meet the requirements. This cable is easy to break in the process of force, resulting in exposed live conductors, resulting in short circuits and leakage discharge.3. High-voltage cable insulation thermal extension project failed. Individual products of the insulation thermal extension of the fusion phenomenon, in the case of high temperature is easy to cause short-circuit accidents. First of all, do not choose the price is too low cable, the price of the finished cable can not be sold below cost. Secondly, consider the qualification of the production enterprise. China's implementation of 3C certification of wire and cable, some products to take the management of the production license, the products of unlicensed enterprises have no quality assurance to speak of. Finally, when buying wire, as far as possible, to the seller for product inspection reports. The quality of wire and cable can not be judged by the naked eye, only through testing to determine whether it is qualified.-4、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
