   The correct choice of wire and cable is very important, what kind of product is in line with national standards?
   In line with the requirements of national standards of wire and cable enterprises, in order to improve product quality, to ensure that products meet national standards, in the purchase of raw materials, production equipment, production technology, etc. will be strict checks.
   First, a good wire and cable brand production of wire and cable products are in line with the standard requirements: smooth round, uniform color. While the appearance of counterfeit inferior products is rough and dull.
   Second, for rubber insulated flexible cable, requiring the appearance of round, sheath, insulation, conductor is not easy to peel off. The counterfeit inferior product appearance rough, large oval, jacket insulation strength is low, hand can tear off.
   Third, the conductor shiny, DC resistance, conductor structure size in line with national standards. In line with the national standard requirements of the wire and cable products, whether aluminum material conductor, or copper material conductors are relatively bright, no oil, so the conductor of the DC resistance in full compliance with national standards, with good electrical conductivity, high security.
   Fourth, the length is accurate. The length is the main intuitive way of distinguishing products that meet the requirements of national standards and counterfeit inferior products. Meet the national standard requirements of the length of wire and cable products in line with national standards 100 ± 0.5m (that is, 100 meters as the standard, allowing the error of 0.5 meters) to protect the interests of consumers.
