Pre-branch cable, wire and cable Xi'an maps, single pre-branch cable

Application of pre-branch cable is mainly divided into three categories 1, power system power system uses an overhead wire and cable products are mainly bare wires, bus (bus), power cables (plastic cable, power cable greaseproof paper (basically plastic power cables instead), rubber cables, insulated overhead cables), branch cable (to replace part of the bus), magnet wire and electrical equipment electrical equipment, wire and cable. 2, information transmission system of wire and cable used for information transmission system are mainly telephone cable, TV cable, electronic cable, RF cable, fiber optic cable, data cable, magnet wire, power cables and other communications or other compound. 3, mechanical equipment, instrumentation systems in this section except for overhead bare wires outside almost all other products have applications, but mainly power cable, magnet wire, data cables, instrumentation cables and the like. The difference between the structure: pre-branch power cable and the difference between ordinary wire is mainly the larger cable size, the structure is more complex. Cable mainly consists of the following group. Conductive core: high conductivity material. Insulation layer: as cable insulation material should have a high insulation resistance, high breakdown electric field strength. Pre-branch cable insulation material often classified. Pre-branch cable with respect to the above technical requirements more stringent, because the building is used for each layer into the family line of the joint, thus sealing work must be done in terms of the joint, so the joint oxidation over time, greatly reduce the life of the cable, Users property is unnecessary losses.
