First, bare copper wire

Bare wires and bare conductor products refer to conductive wires without insulation and without sheaths. They mainly include bare single wires, bare twisted wires, and profiled wire profiles.

Copper and aluminum single wire: including soft copper single wire, hard copper single wire, soft aluminum single wire, and hard aluminum single wire. Mainly used as semi-products of various wires and cables, a small amount is used for the manufacture of communication wires and electrical appliances.

Bare stranded wire: including hard copper stranded wire (TJ), hard aluminum stranded wire (LJ), aluminum alloy stranded wire (LHAJ), steel core aluminum stranded wire (LGJ) are mainly used for the connection of electrical equipment and electronic appliances or components The specifications of the above various twisted wires range from 1.0-300mm2.

Power cables

Power cables are used in the trunk lines of power systems to transmit and distribute high-power electrical power cable products, including 1 to 330KV and above various voltage levels and various insulated power cables.

The cross-section is divided into 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm2, and the number of cores is 1, 2, 3 , 4, 5, 3 + 1, 3 + 2 cores.

Power cables are divided into low-voltage cables, medium-voltage cables, and high-voltage cables according to voltage levels. According to the insulation situation, it is divided into plastic insulated cable, rubber insulated cable, mineral insulated cable and so on.
