The main function of wire and cable is to transmit electromagnetic energy, signal and electromagnetic conversion, used in power installation projects, such as wire and cable, overhead cable, etc. Today, wire and cable professional manufacturers will take you to learn some knowledge of wire and cable.
According to the professional manufacturers of wire and cable product use, what kinds of commonly used wire and cable? It can be divided into bare wire, insulated wire, hot-proof wire, shielded wire, control cable, power cable, radio frequency cable, communication cable, etc. Commonly used insulated wires are PVC insulated flexible wire, PVC insulated wire, rubber insulated wire, nitrile polyvinyl chloride mixed insulated flexible wire, agricultural land directly buried aluminum core plastic insulated wire, PVC insulated nylon sheathed wire, rubber insulated cotton yarn textile flexible wire, power and lighting PVC insulated flexible wire. What kind of occasion is the cable bridge suitable for? Cable bridge is suitable for laying power cables and control cables indoors and outdoors in general industrial and mining enterprises, and can also be used for the indoor and outdoor erection of telecommunications, radio and television departments.
Wire and cable professional manufacturers wire and cable product application: 1, power system. Wire and cable products used in power system mainly include overhead bare wire, busbar (busbar), power cable, rubber sheathed cable, overhead insulated cable, branch cable, electromagnetic wire and electrical equipment wire and cable for power equipment. 2. Information transmission system. The wires and cables used in the information transmission system mainly include local telephone cables, electronic cables, television cables, radio frequency cables, data cables, electromagnetic cables, optical cables, power communication or other composite cables. 3, mechanical equipment, instrument system. In addition to overhead bare wire, almost all other products use this part, but mainly used in power cables, electromagnetic cables, data cables, instrument cables, etc.
The main categories of wire and cable products are: 1. Bare wire and bare conductor products. The main characteristics of this kind of products are: pure conductor metal, no insulation and sheathing, such as copper aluminum bus, steel core aluminum stranded wire, electric locomotive wire. Processing technology is mainly pressure processing, such as melting, rolling, stretching, twisting/compression twisting, etc., products are mainly used in suburban, rural, user main line, switchgear and so on. 2. Power cable. The main features of this type of product are: extruded insulation layer outside the conductor, such as overhead insulated cable or a few cores stranded, such as more than two cores of overhead insulated cable, or sheathed layer, such as plastic/rubber sheathed wire and cable. The product is mainly used in power generation, distribution, transmission, power transformation and power supply lines to transport high-voltage electric energy. 3. Wires and cables for electrical equipment. The main characteristics of this kind of products are: variety specifications, wide range of application, voltage 1kV and below.
