Abstract
The utility model discloses a waterproof and ultraviolet-resistant special cable, comprising a main core, and a belt-wrapping layer, a waterproof layer, an ethylene propylene insulation layer, an anti-ultraviolet layer and a low-smoke and halogen-free protection sleeve, with the latter five covering the main core in order. The middle of the internal part of the belt-wrapping layer is provided with an insulation panel, which evenly divides the belt-wrapping layer into two parts. The main core comprises four groups with each two groups being arranged at two sides of the insulation panel. Three drainage wires and a ground wire core are coated by the internal part of the ethylene propylene insulation layer. The waterproof and ultraviolet-resistant special cable is advantageous in that the cable is good in conductive performance, high temperature resistance, and insulation and water resistance; the core is mainly applied in fields like electric power, metallurgy, chemical petroleum; environment is protected with low smoke and no halogen, and the anti-dragging and anti-oxidation performance is good; the rate of ultraviolet ray shielding reaches to 96.6%.
Description
Technical field
The utility model belongs to field of cables, relates in particular to a kind of waterproof ultraviolet-resistant special cable.
Background technology
In fields such as electric power, metallurgy, chemical petroleums, more and more higher to the quality requirement of cable at present.Not only require cable to possess to conduct electricity very well, anti-ly pull, core is firm, many-sided advantage such as high temperature resistant, anti-oxidant, anti-interference, but also to there is higher ability and ultraviolet resistance, simultaneously, once cable fire can not discharge a large amount of dense smoke and toxic gas as cable in the past, impact rescue, also causes the great security of the lives and property.In the actual production of cable is used, cable only has many-sided requirement of symbol cable, just can better ensure the safe handling of cable.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be to provide a kind of have conduct electricity very well, antiultraviolet, anti-pull, the waterproof ultraviolet-resistant special cable of the advantage such as core is firm, waterproof is anti-oxidant, high temperature resistant, low smoke and zero halogen environmental protection.
The utility model takes following technical scheme to realize: a kind of waterproof ultraviolet-resistant special cable; it comprises wherein master core and master core outside belting layer, watertight composition, second the third insulating barrier, ultraviolet resistant layer and the low smoke and zero halogen protective sleeve of parcel successively; described belting layer bosom is provided with insulation board; described belting layer is divided into two parts by described insulation board; described master core is four groups; divide equally two groups; evenly be arranged in the both sides of described insulation board, three drainage threads of described second the third insulating barrier internal package and a ground connection core.
Described master core is to be formed by two silver-plated insulated wire cores pair twists, and described silver-plated insulated wire cores is by annealed copper aluminium alloy inner wire, interior skinning cortex and zinc-coated wire mesh grid, the outer conductor composition that outer aluminium foil forms.
Described watertight composition is that the cross-linking modified non-hydroscopicity polyvinyl chloride of several circular waterstops forms, and described waterstop is to be made up of the macromolecule water uptake cotton material that adds coal particle, waterproofing unction.
The utlity model has in sum following beneficial effect: this cable conduction performance is good, high temperature resistant, insulative water-proof, core is firmly mainly used in the fields such as electric power, metallurgy, chemical petroleum, low smoke and zero halogen environmental protection, anti-pulling, anti-oxidant, also possess higher ability and ultraviolet resistance simultaneously, rate of ultraviolet shield has been reached to 96.6%.
