Product Name
66-500KV XLPE Power Cable
Construction
Standard
-
IEC 60840 rated voltage 30KV(Um=36KV)and above to 150KV(Um=170KV)extruding insulation power cable and accessories-test meathod and requirement
-
IEC 62067 rated voltage 150KV(Um=170KV)and above to 500KV(Um=550KV)extruded insulation power cable and accessories-test meathod and requirement
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 in the environment temperature is below 0 ℃, and if it is below 0℃, the cable should be heated before installation
Metal sheath
Cable 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 certical shafts )
Plastic Outer Sheath
-
Cable with PVC outer sheath (type02) are suitable for the high voltage cable transmission line with general fireproof requirement and somewhat insulation requirement on the outer sheath.
-
Cables with PE outer sheath (Type03) 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.
