Fundament Data on Cable and Its Classification by Function




Cable refers to wire rod goods used for transferring electromagnetic energy, info and realizing electromagnetic energy transformation. It consists of various voltage classes and all sorts of insulation energy Strong Wire like PVC insulation wire, PVC insulated energy 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 power circuit, application of cable occupies a gradually growing proportion
Cable is essentially composed of core, insulation layer, shielding layer and protection layer 4 parts. The cable core, because the essential part of Strong Wire, will be the conduction part which can be utilized to transport electric energy. Insulation layer is also the indispensible part of multicore cable that separates core and ground, also Solid Wire out of phase in electricity to make sure the electric energy transformation. For shielding layer, conductor screen and insulation shielding layer generally exist in screened control cable of 15kv or above. Protection layer function lies in guarding energy cable from invasion from outdoors impurity and moisture so as to nicely stop external energy from damaging industrial cable
Cable may be classified into numerous kinds based on various techniques. Beneath, let??¡ê¡ès come to that by function.
Strong 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. Usually, bare wire is used in suburb, village, user mainline and switch cabinet.
Solid Wire can also be known as electromagnetic wire. It is cable wire that generates current by cutting electromagnetic line of force in the form of winding or generates magnetic field impact by connecting present. It consists of armoured power cable, covered wire and inorganic insulation wire of various properties. Mainly, it applies in numerous electrical machines and instruments.
Power cable Energy cable refers to Gauge Wire products applied for transporting and allocating large power electric energy amongst primary circuits in power method, such as cross-linked polyethylene insulation power cable applied in building wire. The goods are primarily used in electric energy transmission in electrical energy delivering, allocating, transporting, transferring and supplying circuit with present powerful and voltage high.
Communication cable and optical cable It indicates flat cable used for transmitting telephone, cable, Television, broadcast, digit and other electric info. It requires optical fiber because the optical wave transmission media to conduct information transportation. Including them, radio frequency cable is the cable used for transmitting radio frequency signal in wireless communication, broadcast and relative electric gear.
Gauge Wire for electric equipment It refers to cable that directly send electric power to power connection circuit of various electric gear and utensils from distributor point of power method, some like control cable, aerial cable and cotton covered Gauge Wire. These goods are of widest application range and maximum varieties. Besides, most goods structure and overall performance are determined by combining home like Gauge Wire and application situation of used gear.
