To improve the quality of cables, it is necessary to strictly control the quality of cable raw materials.

For the production enterprises, the first is to strengthen the quality control of the production of cable raw materials. Raw materials are the basis of the product, if you want to control the quality of the product, you must start from the source of production, copper conductor, aluminum conductor and cable material quality directly determines the performance of wire and cable products. It is suggested that enterprises should test some important properties of these raw materials when purchasing them, such as the DC resistance of copper conductors, the mechanical properties and dielectric strength properties of cable materials, etc., to ensure the quality of the purchased raw materials. When raw materials enter the factory, the raw material quality inspection department in the factory inspects the quality of raw materials in batches to prevent the single pursuit of low cost and neglect of raw material quality.
