Essenti Data on Cable and Its Classification by Function




Cable refers to wire rod products used for transferring electromagnetic power, info and realizing electromagnetic power transformation. It includes numerous voltage classes and all sorts of insulation energy Strong Wire like PVC insulation wire, PVC insulated power cable, PVC Pvc Insulated Power Cable and PVC insulated cable. Commonly, power cable is applied in city underground cable, power station extraction circuit, energy provide inside industrial and mining enterprise as well as underwater power transmission line in river and sea. In energy circuit, application of cable occupies a steadily growing proportion
Cable is essentially composed of core, insulation layer, shielding layer and protection layer 4 parts. The cable core, because the important part of Solid Wire, is the conduction part which may be utilized to transport electric power. Insulation layer can also be the indispensible part of multicore cable that separates core and ground, also Solid Wire out of phase in electrical energy to ensure the electric power transformation. For shielding layer, conductor screen and insulation shielding layer generally exist in screened manage cable of 15kv or above. Protection layer function lies in protecting power cable from invasion from outside impurity and moisture so as to well prevent external power from damaging industrial cable
Cable can be classified into many types according to different methods. Below, let??¡ê¡ès come to that by function.
Solid Wire refers to goods with only conductor rather than insulation layer. It consists of various metals like copper and aluminum, single core wire of compound metal as well as stranded cable, soft wiring, molded wire and sectional material used in structured overhead energy cable. In detail, it covers aluminum cable steel reinforced, aluminum Gauge Wire and Pvc Insulated Power Cable. Generally, bare wire is utilized in suburb, village, user mainline and switch cabinet.
Solid Wire can also be known as electromagnetic wire. It is cable wire that generates present by cutting electromagnetic line of force within the form of winding or generates magnetic field effect by connecting current. It includes armoured energy cable, covered wire and inorganic insulation wire of various properties. Primarily, it applies in various electrical machines and instruments.
Power cable Power cable refers to Gauge Wire products applied for transporting and allocating large power electric power amongst main circuits in power method, like cross-linked polyethylene insulation energy cable applied in building wire. The goods are mainly used in electric energy transmission in electricity delivering, allocating, transporting, transferring and supplying circuit with current strong and voltage higher.
Communication cable and optical cable It indicates flat cable used for transmitting phone, cable, Television, broadcast, digit and other electric information. It takes optical fiber because the optical wave transmission media to conduct info transportation. Including them, radio frequency cable is the cable used for transmitting radio frequency signal in wireless communication, broadcast and relative electric equipment.
Gauge Wire for electric equipment It refers to cable that straight send electric energy to energy connection circuit of numerous electric gear and utensils from distributor point of energy system, some like control cable, aerial cable and cotton covered Gauge Wire. These products are of widest application variety and maximum varieties. In addition to, most products structure and overall performance are determined by combining property such as Gauge Wire and application condition of utilized equipment.
