1. The difference between wires and cables The wire is composed of one or several soft wires, and the outer covering is covered with a light and soft protective layer; A cable is composed of one or several insulated and covered wires, which are then covered with a tough outer layer made of metal or rubber. 2. The 3+2 and 4+1 on the wires indicate the number of cores of a cable. There are 2 or 3, 3+2, 4+1, and

Relevant specifications and standards when selecting cable models Since the three technological revolutions, human society has been deeply kidnapped by electricity, and all infrastructure is inseparable from electricity. As an indispensable medium for power transmission, cables have a broad potential market. China has a large area, a large population, amazing electricity consumption, clean energy, complete power generation systems, power transmission systems and power grid construction, which will effectively promote the transformation and development of Chinese society. How to choose the
What is the identification method of LSZH wire? 1. Product name identification method for identification method of low-smoke halogen-free flame-retardant wire. Wire-low-smoke halogen-free flame-retardant polyethylene insulated wire and cable; cable-low-smoke halogen-free flame-retardant polyethylene insulated low-smoke halogen-free flame-retardant polyethylene sheathed power cable. Imitation products generally have a slightly different name, such as polyethylene insulated low-smoke halogen-free sheathed flame-retardant power cable and so on. 2. The skin burn method is the identification method of low-smoke halogen-free flame-retardant wires. There should be no
