How much do you know about the classification of wires and cables?

1, naked Dongguan wire and cable system products

The main characteristics of this kind of products are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper aluminum junction bar, electric locomotive line; The processing technology is mainly pressure processing, such as melting, calendering, drawing, twisting/pressing, etc. Products are mainly used in suburban, rural, user main line, switchgear and so on.

2. Power cable

The main features of Dongguan wire and cable products are: extruded (wound) insulation layer outside the conductor, such as overhead insulated cable, or twisted several cores (corresponding to the phase line, neutral line and ground line of the power system), such as overhead insulated cable with more than two cores, or add a sheath layer, such as plastic/rubber sheath wire and cable. The main process technologies include drawing, twisting, insulating extrusion (wrapping), cable forming, armor and sheath extrusion, etc. There are certain differences in different process combinations of various products.

Products are mainly used in power transmission, distribution, transmission, transformer, power supply lines in the transmission of strong electric energy, through the current (tens of ampere to thousands of ampere), high voltage (220V to 35kV and above).

3, wire and cable variety specifications

The main features of Dongguan wire and cable products are: Varieties of various specifications, wide range of applications, the use of voltage in 1 kv and below is more, to derive new products constantly, in the face of special occasions, such as fireproof cables, flame retardant cable, low smoke zero halogen/low smoke low halogen cables, termite resistance, prevent the mouse cable, resistant to oil/cold/heat resistance, wear-resistant cables, medical/farm/mining cable, thin wire, etc.
