Control wire and cable from the distribution point of the power system to transmit electrical energy directly to a variety of power-using equipment apparatus power connection lines, power cable wire in the power system backbone for the transmission and distribution of large functional electrical energy. Control power cables are mainly 450/750V, power cables are generally rated at 0.6/1kV and above. The same specifications of power cable and control cable in the production of power cable insulation and sheath thickness than the control cable thick.

(a) Control cables belong to the electrical equipment with cables, and power cables are 2 of the five categories of cables.

(B) the standard for control cables is 9330, the standard for power cables is GB12706

(C) the control cable insulation core color is generally black printed white, and power cable low-voltage are generally color separation.

(D) the control cable cross-section is generally not more than 10 square, power cable is mainly to transmit power, generally large cross-section.

From the cable cores, power wire and cable according to the requirements of the power grid, Z more general 5 cores, and control cables to transmit control signals, more cores, according to the standard more than 61 cores, but can also be customized according to user requirements production.
