▎ 摘　　要

NOVELTY - The cable comprises a cable core which has a conductive layer arranged from inside to outside. Each conductive layer comprises several conductor (1) arranged in circumferential direction. The conductor is twisted with each other in each conductive layer. The conductive layer is wrapped with a semi-conductive water blocking tape. An external wall of graphene semiconductor waterproof shielded polyethylene (6) extrudes cross-linked polyethylene insulating layer. A crosslinking polyethylene insulating layer (5) extrudes outside the graphene semiconductor waterproof shielded polyethylene. USE - Waterproof cable. ADVANTAGE - The volume resistivity of the semi-conductive shielding layer is reduced greatly. The homogenizing effect of the shielding layer is improved. The local discharge phenomenon is reduced. DESCRIPTION OF DRAWING(S) - The drawing shows the sectional view of the waterproof cable.
