Control cable
control Cable The executive standard of the product is GB/T 9330-2008.
power cable It is used to transmit and distribute large functional electric energy in the trunk line of the power system, and the control cable directly transmits electric energy from the distribution point of the power system to various electric equipment and appliances Power Supply Connect the line. The rated voltage of power cable is generally 0.6/1kV and above, and the control cable is mainly 450/750V. During the production of power cables and control cables of the same specification, the insulation and sheath thickness of power cables are thicker than that of control cables.
In terms of the number of cable cores, according to the requirements of the power grid, most power cables are generally 5 cores, while control cables are used to transmit control signals, with a large number of cores. According to the standard, 61 cores are more, but they can also be produced according to user requirements.
Usage characteristics of control cable
1. Rated voltage: 450/750V
2. Allowable long-term working temperature of cable conductor: PVC 70 ℃ for insulation and 90 ℃ for XLPE insulation
3. Cable laying temperature shall not be lower than 0 ℃. Recommended allowable bending radius:
- For cables without armor layer, it shall not be less than 6 times of the outer diameter of the cable.
- The cable with armored or copper tape shield structure shall not be less than 12 times of the outer diameter of the cable.
- The flexible cable with shielding structure shall not be less than 6 times of the outer diameter of the cable.
The models that can produce control cables are
