Abstract
The utility model relates to an 110kv environment-friendly termite-prevention cross-linking cable belonging to the electric wire and cable field. The environment-friendly termite-prevention cross-linking cable is formed by a conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer, a semi-conductive water-resisting layer, a metal sheath, an asphaltic corrosion-resistant coating layer, an outer sheath, and a graphite coating layer, wherein the outer sheath is double-layered, namely a high-density PE layer and a polyolefin copolymer termite-prevention sheathing layer wrapped outside the high-density PE layer. The polyolefin copolymer has favorable termite-prevention effect and reduces cable cost. The utility model has the advantages of simple structure, smooth sheath surface, high rigidity, and termite damage prevention.
Description
Technical field
The utility model 110KV environment-friendly type ant-proof crosslinked cable belongs to the electric wire field.Particularly relate to a kind of environment-friendly cable.
Background technology
In recent years, along with the Chinese Urbanization paces are constantly accelerated, following ground cable constantly increased, be subjected to the infringement of termite and bury the ground capacity, China has a lot of regional buried cable oversheaths to suffer the heavy damage of termite, and serious day by day, and the southern area termite is particularly ferocious especially picks.The destruction that buried cable often is subjected to termite causes the accident, because the nest of termite occupies hidden life habit and hazard approach is comparatively special, and that cable is laid in for a long time is underground, therefore generally be difficult for discovering and getting rid of before killed, in case discovery has promptly caused fault or causes the accident, and inspection and maintenance work is very difficult after killed, cause economic loss very big, high-tension cable particularly, the termite-proof research of cable becomes world subject for this reason." medicine type " mainly adopted in anti-the earliest ant measure, but owing to it contains toxicant, adds easily to discharge man-hour, and environment and operator are produced harmful effect, and medicine also the migration stain biological environment can take place during use.Medicine has the half-life in addition, just loses anti-ant behind the general 3-5 and renders a service, and can not reach long-term anti-ant effect, so " medicine type " termite proof cable is banned use of by many countries.So begun the research of " physics method " termite proof cable, nylon 12 is to close the material symbol environmental requirement and that have good anti-ant effect most, but because of its processing technology complexity, is difficult to apply.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art, and a kind of environment-friendly type ant-proof sheath that has is provided, and can prevent termite attack, the environment-friendly type ant-proof crosslinked cable that mass color is sliding, hardness is high.
The purpose of this utility model reaches by following measure, 110KV environment-friendly type ant-proof crosslinked cable is by conductor, conductor shield, insulating barrier, insulation screen, the semiconductive water blocking layer, metallic sheath, the pitch corrosion-inhibiting coating, oversheath, equadag coating constitutes, conductor shield is set on conductor, insulating barrier is set on the conductor shield, insulation screen is set on the insulating barrier, the semiconductive water blocking layer is set on the insulation screen, on the semiconductive water blocking layer metallic sheath is set, scribble the pitch corrosion-inhibiting coating on the metallic sheath, on the pitch corrosion-inhibiting coating, oversheath is set, equadag coating is set on the oversheath, oversheath is double-deck, and one deck is a high density PE layer, at the anti-ant sheath of the extraordinary polyolefin copolymer of high density PE layer outsourcing one deck " Termigon ", so both reach good anti-ant effect, reduced cable cost.
The utility model is simple in structure, and the sheath mass color is sliding, and the hardness height can prevent termite attack.
Description of drawings:
Accompanying drawing 1 is an example structure schematic diagram of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model 110KV environment-friendly type ant-proof crosslinked cable is by copper conductor 1, semiconductive band 2, conductor shield 3, insulating barrier 4, insulation screen 5, semiconductive water blocking layer 6, corrugated aluminium sheath 7, pitch corrosion-inhibiting coating 8, oversheath, equadag coating 11 constitutes, parcel semiconductive band on copper conductor, on the semiconductive band conductor shield is set, insulating barrier is set on the conductor shield, insulation screen is set on the insulating barrier, the semiconductive water blocking layer is set on the insulation screen, the corrugated aluminium sheath is set on the semiconductive water blocking layer, scribble the pitch corrosion-inhibiting coating on the corrugated aluminium sheath, on the pitch corrosion-inhibiting coating, oversheath is set, equadag coating is set on the oversheath, oversheath is double-deck, one deck is a high density PE layer 9, at the anti-ant restrictive coating 10 of high density PE layer outsourcing one deck polyolefin copolymer, outside the corrugated aluminium sheath, scribble the pitch corrosion-inhibiting coating, extrude high density PE layer oversheath earlier, outside high density PE layer oversheath, extrude the anti-ant sheath of the extraordinary polyolefin copolymer of one deck " Termigon " then again, so both reach good anti-ant effect, reduced cable cost.
