Difference between the power cable and control cable

Power cable in the trunk power system for electricity transmission and distribution functions, control cable from the power system of power distribution point to transmit electricity directly to various power connections of electrical equipment. Power cable of rated voltage up to and including 0.6/1 kv of above commonly, control cable is mainly for the 450/750v. The same specifications of the power cables and control cables in production, power cable insulation and sheath thickness thicker than the control cable.

Control cable belong to electrical equipment with cable, and power cable is a cable two of five categories. Standards of control cable is 9330, power cable GB12706 is the standard. The color of the control cable insulation wire core is usually white, black and low are generally color separation power cable.
Control cable cross section is generally not more than 10 square, power cable is mainly the power of that are generally large cross section. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet, again big cross section, can do manufacturers is relatively less, and control the cross section of the flexible cable generally smaller, generally no more than 10 largest square. Some conclusions from the cable, power cable according to the request of power grid, most commonly for five core, and control cable transmission control signal, some more, according to the standard terms of more than 61 core, but also can produce according to user requirements.
