NOVELTY - This utility new type claims a super graphite alkenyl for 110-220 kV power cable, comprising a conductor, the conductor outer layer concentric winding type conductor shielding layer is set, extrusion type conductor shielding layer, an insulating layer and an insulating shielding layer, wherein the extruding type conductor shielding layer, an insulating layer and an insulating shielding layer is a three-layer co-extrusion structure; the insulating shielding layer are orderly arranged outside the waterproof layer, a metal jacket and a non-metallic outer sheath. The wire core of the utility realizes the conductor shield and insulation and insulating smooth without gap contact with the insulating shielding layer, improve the homogenization effect, improving water-blocking layer, a buffer effect, so as to greatly improve the safe operation of the cable.
