Abstract
The present invention relates to a cable, in particular a compound cable having flame retardant and lightning protection function used mounted in the open air. It contains cable core, metal strap and insulating coating, featuring said insulating coating made of (by weight) ethylene copolymer 50-60 per cent, epoxy 5-10 per cent, fire retardant 20-30 per cent, antioxidant 1-5 per cent, silica gel 5-10 per cent, said metal strap layer wound by zinc oxide strap, silica gel isolating layer set between insulating layer and zinc oxide strap layer, insulating coating coated with silica gel protective layer. Said invention solves cable easy stroke by lightning stroke through improvement of cable core outside material and has good dirt proof and waterproof
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of be used for open-air set up in the open have a composite cable fire-retardant, lightning protection function.
Background technology
Cable is made up of cable core, insulating barrier, strap layer and insulating coating usually.This class cable sets up when using in the open being applied to the field, and the accident that occurs meeting with thunderbolt through regular meeting takes place.In case meet with thunderbolt, burning will appear in cable, causes to have a power failure and environmental pollution.Chinese patent CN1588561A discloses a kind of environment-friendly cable line, is characterized in having used preparations such as ethylene-vinyl acetate copolymer and fire retardant in outer insulating material, though solved environmental protection and fire-retardant problem, can not solve lightning-arrest problem.
Summary of the invention
Purpose of the present invention is exactly the defective that exists at prior art, and a kind of composite cable fire-retardant, lightning protection function that has is provided.
Its technical scheme is: comprise cable core, insulating barrier, strap layer and insulating coating; it is characterized in that described insulating coating makes by the material of following percentage by weight is compound: ethylene copolymer 50-60%, epoxy resin 5-10%, fire retardant 20-30%, antioxidant 1-5%, silica gel 5-10%; described strap layer is to replace strap layer by the zinc oxide belt; between insulating barrier and zinc oxide belt, also be provided with the silica gel separator, at the silica gel protected layer of insulating coating coating.Ethylene copolymer comprises ethylene-chlorotrifluoro-ethylene copolymer, ethylene-vinyl acetate copolymer (EVA), polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene copolymer (ETFE).The thickness of insulating coating is between the 0.5-6.5 millimeter, and between the zinc oxide belt thickness 1-5.5 millimeter, the thickness of silica gel separator is between the 0.1-0.5 millimeter, and silica gel protected layer thickness is between the 5-20 micron.
The present invention has at first solved cable and has set up the problem of being struck by lightning easily when using in the open air by the improvement of cable core exterior material, reaches lightning protection function; Secondly in the insulating coating material, add fire retardant, can improve the problem that cable is high temperature resistant and burn; Last outer coating silica gel has good anti-soil, waterproof action.
Description of drawings:
Accompanying drawing is a cross-sectional view of the present invention.1 is cable core among the figure, the 2nd, and insulating barrier, the 3rd, strap layer, the 4th, insulating coating.
Specific embodiment
With reference to accompanying drawing, cable of the present invention comprises: 1 cable core, 2 insulating barriers, 3 zinc oxide bands and 4 insulating coatings.Improvements comprise: (1) insulating coating is compound the making of material that comprises following percentage by weight: ethylene copolymer 50-60%, epoxy resin 5-10%, fire retardant 20-30%, antioxidant 1-5%, silica gel 5-10%, can improve the high temperature resistant and anti-flammability of overcoat.(2) original strap layer is changed by the winding of zinc oxide band winding replacement metal tape, realize lightning protection function.(3) between insulating barrier and zinc oxide belt, also be provided with the silica gel separator, to increase the insulation property and the tensile property of cable.(4) at the silica gel protected layer of insulating coating coating, can improve cable antipollution and water resistance.Preparation flow is with reference to prior art.
