Abstract
The invention relates to a novel composite-shielding high-voltage crosslinked polyethylene insulated power cable. From interior to exterior, the cable comprises, in order, a copper conductor, a wrapping semiconductive nylon tape, a conductor shielding layer, an insulating layer, an insulation shielding layer, a wrapping semiconductive water-blocking tape, a copper strip shielding layer, a PP wrapping tape, an extruded inner protective layer, a metallic shielding layer, a non-woven fabrics wrapping layer, a PE oversheath, and a graphite coating layer. The power cable has a simple and novel structure. By using VCV three-layer coextrusion and a composite shielding technology, electrical property and water-blocking performance of the cable are improved, and service life of the cable is prolonged.
Description
Technical field
The present invention relates to a kind of power cable, relate in particular to a kind of NEW TYPE OF COMPOSITE shielding high-voltage cross-linking polythene insulated power cable.
Background technology
High voltage power cable is very important to stability, fail safe, the integrality of electric energy transmitting; " screen " essence in the high-voltage crosslinking structure is a kind of measure that improves Electric Field Distribution, avoids cable generation partial discharge phenomenon and the generation that damages punch-through.
Summary of the invention
The present invention provides in order to overcome the above problems that a kind of shield effectiveness is good, block-water performance is good, the NEW TYPE OF COMPOSITE of long service life shielding high-voltage cross-linking polythene insulated power cable.
Technical scheme of the present invention is: described cable is followed successively by copper conductor, wrapped semiconductive nylon tape, conductor shield, insulating barrier, insulation screen, wrapped semiconductive waterstop, copper strips screen, PP twining package tape from the inside to the outside, extrudes sheath, metal screen layer, nonwoven fabrics lapping layer, PE oversheath and graphite applying layer.
Described conductor shield, insulating barrier, insulation screen adopt three-layer co-extruded technology to extrude simultaneously.
Novelty of the present invention simple in structure adopts VCV three-layer co-extruded technological with composite shielding, has promoted electrical property, the waterproofing type ability of cable, has prolonged the useful life of cable.
