In the following locations to control: ①, cable introduction leads to buildings, tunnels, floors and the main walls; ②, leads to two meters high ground, 250mm deep underground; ③ cable and underground pipe cross or close when the distance is not required; , Cable and road, tramway and rail crossing; ⑤, the factory may be subject to mechanical damage and pedestrians accessible location. When selecting a pipe diameter, the inner diameter is 50% larger than the outer diameter. Wire and cable is the transmission of electrical energy, electrical signals and electromagnetic energy conversion of wire products. Cables are usually made up of cable cores that transmit electrical or electrical signals and protective, insulated sheaths. A cable with only one cable core and a smaller diameter is often referred to as a wire. Also some wires do not have insulated sheaths, called bare wires. The cable in the cable is made of a metal material with good electrical conductivity, usually copper (good electrical conductivity) or aluminum (lower cost).
