Teach You To Distinguish Power Cable And Control Cable
Power cables are used for transmission and distribution of electrical power in the main line of the power system, the control cables transfers electrical energy directly from the distribution point of the power system to the power supply various power connections lines of electrical equipment.
The rated voltage of power cable is generally 0.6/1kv and above (such as VV, YJV), the control cable is mainly 450/750v (such as KVV/KVVP).
The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness is thicker than the control cable’s.
1.The control cable standard is GB / T9330 power cable, power cable standard is GB / T12706-2008.
2.The control cable insulating wire core color is generally black and white printing,the low voltage power cable insulating wire core color is generally color separation.
3.Control cable cross-sectional area is generally not more than 10 square meters,power cables are mainly transmission of electricity, are all generally large cross-section, as large as 500 square meters (the scope of the production of conventional manufacturers).
From the number of cable cores, the power cable according to the requirements of the grid, the most is generally 5 core, while the control cable used for transmission control signal, the core number is more, according to the standards, there are more than 61 core, but can also be produced according to user requirements.
