Power cable ( power line ) in power system main line for transmission and distribution functions of electric energy, control cables from power system distribution point for the electric energy is transmitted directly to the various electrical equipment power connections. Power cable is generally rated voltage0.6/1kV and above, the main control cable450 /750V. The same specifications of the power and control cables in the production, power cable insulation and sheath control cable thickness thickness ratio.

First of all, control cable belongs to the electric appliance equipment cables, and power cable is a cable five categories in the 2.

Control cable standard is 9330, the standard is GB12706power cable

Control cable insulated core color is generally white, black printing and power cable low voltage is usually color.

Control cable cross section are generally not more than 10square, power cable is the main transport power, are generally large cross section.

Due to the above mentioned reasons people, power cables General specifications can be larger, to 500square ( conventional manufacturers can produce a range of big cross section ), as do manufacturers less, while the control cable cross section is generally small, the largest generally does not exceed 10square.

From the cable core number sense, power cable according to the power requirement, most commonly 5core, while the control cable transmission control signal, count more, according to the standards of the61core, but also can produce according to user requirements.
