Copper content of communication cables
Communication cable: 3 * 400 * 8.94 g / cubic millimeter * 1000/1 meters long, total weight of cable (g) * 100% is the copper content of cable.The communication cable is composed of a plurality of insulated wires or conductors, and the cable core is provided with a communication circuit with a sealing sheath. Some outside the sheath is also equipped with an outer protective layer.
Communication cables are materials used for power, communications and related transmission purposes. "Wires" and "cables" do not have strict boundaries. Usually the small number of core products in diameter, simple structure of the product was called wire, no insulation called bare wire, the other called the cable; the conductor cross-sectional area larger (greater than 6 mm2) called wire, the smaller (less than or equal to 6 mm2) called small wires, insulated wire, also known as wire cloth. The price of wire and cable is fixed with the fluctuation of copper price.
