Product Summary

XLPE-insulated cables offer various advantages over conventional paper-insulated oil-filled cables.

They require no oil supplying system and less maintenance, in addition to-boasting smaller charging current and dielectric loss. Another great advantage of XLPE cables is their greater continuous and short-circuit current carrying capacity resulting from excellent thermal characteristics. Based on these features, the application of XLPE cables has rapidly extended to extra-high-voltage cable; 275kV XLPE cable was applied in the field in Japan in 1981 by FUJIKURA.

Since the first supply of XLPE-insulated cables in the 1950's, FUJIKURA has been providing substantial quantities of XLPE cables to customers both at home and abroad. Further, R&D activities have been conducted in the areas of performance and characteristics of actual XLPE cables, as well as their manufacturing process and installation procedures.

Key Features

Since first supplying XLPE-insulated cable in the 1950's, FUJIKURA has been supplying substantial quantities to satisfied customers.

The total length of 66 kV and higher voltage XLPE cables supplied by FUJIKURA reached 4,000 km by the end of 1991.

• The first delivery of 110 kV XLPE cabs was made in 1972

• Since then, substantial lengths of 110 kV and higher voltage XLPE cables supplied by FUJIKURA have demonstrated trouble-free operation.

• Particularly, in 1982, FUJIKURA supplied and installed 275 kV XLPE cables for the world's longest cable route with this voltage.

FUJIKURA developed a new vulcanizing system for the XLPE insulation layer which we trade-named the "Perfectly Dry-Curing System."
In this system, silicone oil is used as the heating and cooling medium without resorting to steam or water.

Characteristics

Characteristics of XLPE Cable Produced by our "Perfectly Dry-Curing

System"

• Very smooth, good contact between the insulation and screening layer by employing a three-layer common extruding method.

• Very high performance, eliminating contaminants in the insulation layer by adopting our "Super Clean Material Supplying System."

• Completely circular insulation without eccentricity results from using a special crosshead and die nipple in extruding.
