Wire and Cable(2)


Bare wire system products
Bare wires institutional products main features are: pure metal conductor, no insulation and sheathing layer, such as ACSR, copper and aluminum bus, electric locomotive lines; processing technology is mainly pressure processing, such as smelting, rolling, drawing, stranding / compact-stranded, etc.; product is mainly used in the suburbs, rural areas, users mainline, switch cabinets.



Power cables
Power cable main features are: outer conductor squeeze (around) package insulation layer, such as overhead insulated cables, or a few core twisted (corresponding to the power system phase, neutral and ground), if two or more cores overhead insulated cables or increases the jacket layer, such as plastic / rubber wire and cable. The main technology has drawn, stranded, insulated extrusion (wrapped), a cable, armored and protective layer extrusion, combination of different processes of various products have some differences.

Power cables are mainly used in hair distribution, transmission, transformation, power lines in strong electric power transmission, the current through the large (tens of thousands of security to security), high voltage (220V to 35kV and above).
