Product Description
CABLE STANDARDS
GB/T11017,GB/Z18890,GB/Z22078,IEC,BS,ASTM and etc. upon request.
Operating Environment
- Max admissible temperature for conductor: 90℃ under normal running condition; 250℃ under short circuit(max. duration is 5s)
- Min bending radius is recommended to be 20 times of cable overall diameter
- PVC sheathed cables shall not be installed if the environment temperature is below 0℃,and if it is below 0℃,the cable should be heated before the installation
Metal Sheath
- Cables with corrugated aluminum sheath can be especially suitable for the following conditions in addition to the normal ones
- Cables with corrugated aluminum sheath: places where there is not much corrosion but much requirement for mechanical strength (e.g. direct connection to transformers, laying on bridges and in vertical shafts)
Plastic Outer Sheath
- Cables with PVC outer sheath ( Type 02 ) are suitable for high voltage transmission line with general fireproof requirement and centain insulation requirement for the outer sheath
- Cables with PE outer sheath( Type 03 )are suitable for high voltage transmission line directly buried underground with higher insulation requirement on the outer sheath; and if they are laid in tunnels or vertical shafts, anti-fire and flame-retardant measures must be taken
