Abstract
The high voltage power cable of the present invention, including core, wraps up the packed layer of described core, around the stranding lapping layer wrapped in outside described packed layer, it is coated in the secondary shielding coating outside described stranding lapping layer, around the lapping layer wrapped in outside described secondary shielding coating, is extruded in the oversheath outside described lapping layer；Described core, by conductor, is extruded in the insulating barrier outside described conductor, the first curtain coating being coated in outside described insulating barrier, around the fire-retardant lapping layer composition wrapped in outside described first curtain coating.High voltage power cable of the present invention, have employed the curtain coating design of the special construction of cable and bilayer；Owing to have employed novel shielding coating；High voltage power cable of the present invention has electromagnetism interference, anti-lightning and the uniform electric field of excellence, improves the characteristic of power supply quality.This cable has stronger anti-corrosive properties, acid and alkali resistance and organic solvent simultaneously；Owing to not having metal screen layer, therefore this cable can fixedly mount, also may move use, has the features such as performance softness, good bending property.
Description
Technical field
The present invention relates to a kind of cable, particularly relate to a kind of high voltage power cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, product variety Service Efficiency and domestic market
Occupation rate is all more than 90%.Worldwide, China's electric wire gross output value has exceeded the U.S., becomes the first big electricity in the world
Line cable manufacturing country.Along with China's wires and cables industry high speed development, creation of new enterprise quantity constantly rises, industry overall technology
Level is largely increased.Power cable is for transmitting and distribute the cable of electric energy.It is usually used in Urban Underground electrical network, electric station
Lead line, the in-line power of industrial and mining establishment and the submarine transmission line in mistake river, excessively sea.Ratio in power circuit, shared by cable
Weight is just gradually increased.Power cable is to produce in order to transmitting and to distribute the cable of high-power power in circuit the master of power system
Product, including 1-500KV and any of the above electric pressure, the power cable of various insulation.Screen layer is for homogeneous conductive
Core typically has conductor shield and insulation screen with insulation electric field, 6kV and above middle-high voltage power cable, and part is low
Voltage cable is not provided with screen layer.Screen layer has semi-conductive screen and metallic shield two kinds.(1) semi-conductive screen semi-conductive screen
Layer is generally arranged at the outer surface of conductor wire core and the outer surface of insulating barrier, is called inner semiconductor layer and outer semiconductive
Screen layer.Semiconductive shielding layer is that the lowest by resistivity and thinner thickness semiconductive material is constituted.Inner semiconductor layer is
For uniform line core outer surface electric field, it is to avoid because of conductive surface is rough and the air gap of the stranded generation of core and cause conductor and
There is shelf depreciation in insulation.Out semiconductor layer contacts very well with insulating barrier outer surface, and with protective metal shell isoelectric level, it is to avoid
Because of defects such as cable insulation face cracks with protective metal shell generation shelf depreciation.For there is no the mesolow electricity of protective metal shell
Power cable, in addition to being provided with semiconductive shielding layer, metal screen layer to be increased.Metal screen layer is generally by copper strips or copper wire
Wrapped form, primarily serve the effect of shielding electric field.
Summary of the invention
It is an object of the invention to overcome the technological deficiency of existing cable, it is provided that a kind of have good physics, mechanical performance,
Environmental protection flame retardant performance；The most also there is electromagnetism interference, anti-lightning and the uniform electric field of excellence, improve the characteristic of power supply quality
High voltage power cable.
The high voltage power cable of the present invention, including core, wraps up the packed layer of described core, around wrapping in outside described packed layer
Stranding lapping layer, be coated in the secondary shielding coating outside described stranding lapping layer, around wrapping in outside described secondary shielding coating
Lapping layer, is extruded in the oversheath outside described lapping layer；Described core, by conductor, is extruded in the insulating barrier outside described conductor, is coated with
Overlay on the first curtain coating outside described insulating barrier, around the fire-retardant lapping layer composition wrapped in outside described first curtain coating.
As optimization, this high voltage power cable, described core, by tinned copper conductor, is extruded in outside described tinned copper conductor
Thermoplastic polyester elastomer insulating barrier, is coated in the first curtain coating outside described thermoplastic polyester elastomer insulating barrier, wrapped
Synthetic mica tape fire-retardant lapping layer composition outside described first curtain coating.
As optimization, this high voltage power cable, including four cores, the polypropylene guipure wrapping up described four cores is filled
Layer, around the stranding non-woven fabrics lapping layer wrapped in outside described polypropylene guipure packed layer, is coated in described stranding non-woven fabrics lapping layer
Outer secondary shielding coating, around the Kapton Tape lapping layer wrapped in outside described secondary shielding coating, is extruded in described polyamides
Polyolefin elastomer oversheath outside imines adhesive tape lapping layer.
