Classification of power cables

Wire and cable include many types of products, the following is to introduce the classification of power cables. By product category:

1) bare wire and bare conductor products

2) Power cable

3) Electrical equipment with wire and cable

4) Communication cables and optical fiber

5) magnet wire

6) Wire and cable derived new products

Power cables are mainly oil-impregnated paper insulated lead-power cables, rubber insulated power cables, PVC insulation, PVC sheathed power cables, self-contained oil-filled cables.

PVC insulated power cable

Vinyl chloride plastic physical and mechanical properties better, a lot for the manufacture of 1kV and below low-voltage power cables for low-voltage power distribution system.

Rubber insulated power cable

Flexible cables, removable power cables, mainly for businesses often need to change the laying position of the occasion. The use of natural rubber insulation, voltage level is mainly 1KV, can produce 6KV level

Overhead insulated cables

The Overhead conductor with insulation, erected on the pole, insulation design margin can be less than the power cable. Insulation using polyvinyl chloride or cross-linked polyethylene. Generally made of single-core, but also can be 3 to 4 phase insulated core strands twisted into a bundle, without sheath, called bundle overhead cable.

Frequency conversion cable

Working frequency is 30 ~ 300Hz, choose cross-linked polyethylene as insulation material.

Rubber cable

A multi-strand thin copper wire conductor, outsourcing of rubber insulation and rubber sheath of a soft and removable cable.

Flame retardant cable

Under specified test conditions, the sample is burned, and after the test fire source is removed, the spread of the flame is only within the limited range, residual flame or residual cable can be extinguished within a limited time. Features are likely to be burned out of operation in a fire situation but can prevent the spread of the fire.

Fire-resistant cable

Refers to the specified test conditions, the sample is burned in the flame, within a certain period of time can still maintain the normal operation of the performance. The characteristic is that the cable can still maintain the normal operation of the circuit for a period of time under the burning conditions. Class A fire-resistant cable fire resistance is better than the B class.

Waterproof cable

The Insulation layer, filling layer and sheath layer are made of high-density waterproof rubber, it has a strong waterproof performance. Suitable for submersible pumps, underwater operations, fountains, underwater lights and other water treatment equipment.

Cold-resistant cable

Widespread use of the harsh alpine environment, in the alpine climate, still maintain good flexibility and bending properties. Conductors using multi-strand fine twist and fine twisted into bundles, an oxygen-free copper wire for the conductor.

Environmental cable

Halogen-free, high transmittance, high flame retardancy, no corrosive gas, waterproof, UV resistant, heavy metal-free, recyclable.
