1. Standard of Product
The 110kV XLPE Insulated power cable is produced according to the standard GB/T11017 Power cable with cross-linked Polyethylene insulation and their accessories for rated voltage of 110kV, which are equivalent to IEC 840 Tests For power cables with extruded insulation for rated voltage above 30kV(Um=36kV)up to 150kV(Um=170kV). AEIC CS7 Specifcations for crosslinked polyethyene insulated shielded power cable rated 69 through 138kV. The 220kV XLPE cable to standard GB/Z18890 Power cable with cross-Linked polyethlene insulation and their accessories for rated voltage of 220kV which is equivalent to SS 424 14 17 power cables-XLPE-insulated cables with extruded oversheath and rated voltage 12-420kV-Testing, and some extension with reference to IEC 840 and AEIC CS7.

XLPE insulated power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE cable has high electric
strength, mechanical strength, high-ageing resisting, environmental stress resisting aiti-chemical, corrosion, and simple construction, using
convenient and higher operating of long term temperature. It can be laid with no drop restriction.
Various of flame-retardant XLPE cable can be manufactured with three technology .The flame-retardant cable covers all kinds of low-smoke,
halogen
free, and non-smoke non-halogenated and three classes of A,B,C.
