Introduction of Shielded control cable
Shielded control cable is fit for AC rated voltage 450V / 750V and DC rated voltage 1000V and the following operation control, monitoring control, protection control etc. circuits electrical system connection.
Standard of Shielded control cable
GB/9330-88 Plastic insulated control cable
Characteristics of Shielded 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.
Application of Shielded control cable
Copper core PVC insulated PVC sheathed shield control soft cable for metallurgical, power, petrochemical and other industrial and mining enterprises in the exchange of rated voltage (Uo / U) 450 / 750V and below electrical instrumentation, distribution device transmission , Control and measurement systems.
