HVDC Engineering Cables, Instrumentation Cables

The HVDC engineering cables and instrumentation cables are designed and produced according to the standard of Q/321011KLA208-2009, and are suitable for different conditions. They are designed to work as control cable and measuring cable with rated voltage of 0.6/1kV or lower, instrumentation cable for connections of 300/500V computer, as well as control and measuring cables for other control device and detecting device.

Service Property
1. Rated voltage U0/U: 0.6/1kV or lower for HVDC engineering cable, and 300/500V or lower for instrumentation cable.
2. Max. working temperature: 70℃ for general type, and 90℃ for XLPE type
3. Min. ambient temperature when working: -40℃ for fixed laying, and -15℃ for non-fixed laying
4. Min. bending radius: 6 times of cable outer diameter for non-armored type, and 12 times of overall diameter for armored type.
