Introduction of Control Cable
Control cable include PVC and XLPE insulated control cable, flame-retardant control cable and high-temperature resistance control cable. The control cable is mainly designed for controlling, monitoring circuit and protective lines with AC rated voltage U0/U of 450/750V and below. It is used to interconnect electric advices and instruments between electrical equipment.
Characteristics of Control Cable
1. Power frequency rated voltage Uo/U :450/750V or 0.6/1KV
2. The permissible long-term maximum working temperature of the cable conductor is 70 ℃.
3.Cable laying ambient temperature should not be less than 0 ℃, if the ambient temperature is below 0 ℃, the cable should be preheated.
4.The recommended bending radius for cables is as follows:
No armored cable, should not be less than 6 times the cable diameter;
Armored or copper tape shielded cable, should not be less than 12 times the cable diameter;
Shielded flexible cable, not less than 6 times the cable diameter.
