66-500KV XLPE Power Cable

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.
