Central Knowledge on Cable and Its Classification by Function




Cable refers to wire rod goods used for transferring electromagnetic energy, information and realizing electromagnetic power transformation. It consists of numerous voltage classes and all kinds of insulation energy Solid Wire like PVC insulation wire, PVC insulated energy cable, PVC Pvc Insulated Power Cable and PVC insulated cable. Generally, energy cable is applied in city underground cable, energy station extraction circuit, power supply inside industrial and mining enterprise as well as underwater power transmission line in river and sea. In power circuit, application of cable occupies a gradually growing proportion
Cable is basically composed of core, insulation layer, shielding layer and protection layer four parts. The cable core, as the important part of Strong Wire, will be the conduction component which can be utilized to transport electric power. Insulation layer is also the indispensible a 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 commonly exist in screened control cable of 15kv or above. Protection layer function lies in protecting power cable from invasion from outside impurity and moisture so as to well stop external energy from damaging industrial cable
Cable may be classified into numerous types according to various techniques. Below, let??¡ê¡ès come to that by function.
Strong Wire refers to goods with only conductor instead of insulation layer. It includes numerous metals like copper and aluminum, single core wire of compound metal also as stranded cable, soft wiring, molded wire and sectional material utilized in structured overhead power cable. In detail, it covers aluminum cable steel reinforced, aluminum Gauge Wire and Pvc Insulated Power Cable. Usually, bare wire is utilized in suburb, village, user mainline and switch cabinet.
Solid Wire is also called electromagnetic wire. It is cable wire that generates current by cutting electromagnetic line of force in the form of winding or generates magnetic field effect by connecting present. It includes armoured power cable, covered wire and inorganic insulation wire of numerous properties. Primarily, it applies in numerous electrical machines and instruments.
Energy cable Power cable refers to Gauge Wire products applied for transporting and allocating big energy electric power amongst primary circuits in energy method, like cross-linked polyethylene insulation energy cable applied in developing wire. The products are primarily used in electric energy transmission in electrical energy delivering, allocating, transporting, transferring and supplying circuit with current strong and voltage higher.
Communication cable and optical cable It indicates flat cable utilized for transmitting phone, cable, Television, broadcast, digit as well as other electric information. It requires optical fiber because the optical wave transmission media to conduct info transportation. Such as them, radio frequency cable is the cable utilized 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 power to energy connection circuit of various 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 range and maximum varieties. In addition to, most goods structure and performance are determined by combining home like Gauge Wire and application condition of utilized gear.
