Power cable is the backbone of power system, which is used to transmit and distribute large-scale electric energy. The rated voltage is generally 0.6/1kv and above. The control cable directly transmits the electric energy to the power supply connection of various electrical equipment and appliances, and its rated voltage is 450 / 750V. This makes the insulation and sheath thickness of power cable thicker than that of control cable in production. The differences are summarized as follows:
1. Control cables belong to electrical equipment cables, and power cables are two of the five categories of cables.
2. The standard of control cable is 9330, and that of power cable is gb12706
3.The color of insulated core of control cable is generally black and white, and the low voltage power cable is generally color separated.
4.The cross section of the control cable is generally less than 10 square meters, and the power cable is mainly used to transmit power, generally with large cross-section.
