Abstract
The utility model relates to an extrusion-free external shielding environment-friendly type medium voltage power cable, and belongs to the technical field of environment-friendly type medium voltage power cables. The technical scheme is that the cable comprises a conductor wire core (1), an internal shielding layer (2), a cross-linking polyethylene insulating layer (3), a silicone oil coated layer (4). A semi-conductive tape layer (5), a copper tape layer (6), a non-woven fabric layer (7) and an external sheath (8). The conductor wire core (1) is externally wrapped with the co-extrusion internal shielding layer (2), the cross-linking polyethylene insulating layer (3), the silicone oil coated layer (4), the semi-conductive tape layer (5), the copper tape layer (6), the non-woven fabric layer (7) and the external sheath (8) in turn. The semi-conductive tape layer, the copper tape layer and the non-woven fabric layer are arranged for winding. The beneficial effects of the cable are that all materials of the integral cable meet the ROHS environmental protection requirement and the electrical property requirement. Shielding of the 6.6KV cable is realized by winding the semi-conductive tape and the copper tape so that installation is facilitated for users and power distribution cabinet special construction requirements are met.
