Abstract
The utility model relates to a 110kV cross-linked polyethylene insulated power cable. An inner insulated layer, a middle insulated layer and an outer insulated layer are extruded around conductors by means of triple extrusion, dry crosslinking and continuous vulcanization. The conductors and the three insulated layers form an insulated core. A water-stop buffering semiconductive shield layer is wrapped around the insulated core, an aluminum sheath is extruded around the semiconductive shield layer, an anti-corrosion bituminous layer is coated on the periphery of the aluminum sheath, and an outer sheath and an outer semiconductive sheath are extruded around the anti-corrosion bituminous layer by means of double co-extrusion. The 110kV cross-linked polyethylene insulated power cable is fine in electrical and mechanical properties, can meet various environmental requirements, and has excellent water stopping performance and corrosion resistance.
