Abstract
The invention discloses a high-voltage direct-current polymeric cable, which comprises a conductor located at the center of the cable. A semi-conductive tape is wrapped outside the conductor; a semi-conductive conductor shielding layer, an insulating layer and an outer semi-conductive insulation shielding layer are sequentially arranged outside the semi-conductive tape to form an insulating wire core; a buffer layer is wrapped outside the insulating wire core; a metal sheath layer is coated outside the buffer layer; an anti-corrosion asphalt or hot-melt adhesive layer is coated outside the metal sheath layer; and the outermost layer is provided with an outer protection layer. The invention provides the high-voltage direct-current polymeric cable which is specially applied to direct-current power transmission, has the advantages of good electric and mechanical performances, excellent waterproof capability and anti-corrosion property, and can meet various environmental requirements.
Description
Technical field
The present invention relates to the electric wire field, specifically is a kind of HVDC polymerization cable.
Background technology
Along with the develop rapidly and the technological progress of national economy, the direct current transportation technology will be widely used in following electric power transfer, be used to strengthen electric power networks, reduce power outages, satisfy the future market demand.The HVDC transmission cable is the important foundation of direct current transportation, at present also is respectively to develop the research and development target that producer and unit weight are wanted in the field of cables.
Summary of the invention
Technical problem to be solved by this invention provides a kind of electric, good mechanical property, can satisfy various environmental requirements, has the HVDC polymerization cable of excellent block-water performance and antiseptic property.
A kind of HVDC polymerization of the present invention cable, it comprises the conductor that is positioned at cable center, wrapped semi-conductive tape outside conductor, outside semi-conductive tape, set gradually semiconductive conductor shield, insulating barrier and outside the semiconductive insulation screen form insulated wire cores; Wrapped resilient coating outside insulated wire cores coats metal sheath layer outside resilient coating; Outside metal sheath layer, apply one deck anti-corrosion asphalt or hot melt adhesive layer; Outermost layer is provided with outer jacket.
Said conductor is to adopt to press circle or 4～6 parts of coppers cut apart or aluminum conductor.
Said semiconductive conductor shield, insulating barrier and outer semiconductive insulation screen extrude with three-layer co-extruded dry cross-linking continuous vulcanization mode and form.
Said resilient coating adopts with the semiconductive zone of swelling that blocks water that overlap mode is wrapped to form.
Said metal sheath layer is for extruding aluminium sheath, perhaps argon arc welding aluminium sheath, and perhaps copper wire is dredged around+aluminium cover combination layer.
Said outer jacket is that oversheath adds outer semiconductive jacket structure or oversheath adds graphite semiconducting coating structure.
Said oversheath adopts high electrical performance polyvinyl chloride or polyethylene or low-smoke halogen-free polyolefin material.
Beneficial effect: the invention provides a kind of electric, good mechanical property, can satisfy various environmental requirements, and power outages is little.Owing to outside aluminium sheath, apply one deck anti-corrosion asphalt or hot melt adhesive layer, the anti-corrosion asphalt layer outside with the double-layer coextrusion method extrude oversheath and outside semiconductive sheath or individual layer extrude oversheath and add the graphite semiconducting coating; So have excellent block-water performance and antiseptic property.
