The utility model discloses a high fire -retardant rubber sleeve cable for coal mine structure is comparatively simple, convenient and practical, suitable further the popularization and application.
Description
Technical field
The utility model relates to the structure-design technique field of cable product, more particularly, relates to a kind of colliery high flame retardant Plastic-sheathed Cable.
Background technology
Cable product is that the movement under coal mine is laid, generally use in harsh environments, as: the combined stress effect being subject to overbending, stretching, torsion, mechanical external force impact, this can make the combination property of cable decline, and useful life shortens cable long term frequent.Down-hole coal excavation place is at very rugged environment mostly, usual gas, concentration of methane gas are higher, belong to inflammable and environment that is susceptibility-to-corrosion, for preventing accidental bodily injury and preventing unnecessary peril, this just requires that the cable installed has good fire resistance and decay resistance.Therefore, develop a kind of structure simple, convenient and practical colliery high flame retardant Plastic-sheathed Cable is those skilled in the art's technical problems urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model is: for overcoming the technical problem mentioned in above-mentioned background technology, now provides a kind of structure simple, convenient and practical colliery high flame retardant Plastic-sheathed Cable.
The utility model solves the technical scheme that its technical problem adopts: a kind of colliery high flame retardant Plastic-sheathed Cable, this cable comprises the first conductor cores, the second conductor cores, the 3rd conductor cores, is coated on the ethylene propylene rubber insulated layer of the first conductor cores, the second conductor cores and the 3rd conductor cores outer surface respectively, is coated on the anti-interference layer of the first conductor cores, the second conductor cores and the 3rd conductor cores outer surface, is coated on inner restrictive coating and the external sheath layer of anti-interference layer outer surface successively;
Described inner restrictive coating outer surface is provided with continuous print external screw thread, and external sheath layer inner surface has the internal thread matched with above-mentioned external screw thread; Described anti-interference layer is that metal material is made, and being filled with between anti-interference layer inwall and ethylene propylene rubber insulated layer outer wall can the rigid foam of fixed conductor core position, and external sheath layer is made up of resistant material, and inner restrictive coating is made up of fire proofing.
Further preferably, the average thickness of described inner restrictive coating and external sheath layer is equal.
Further preferably, the thickness of described anti-interference layer is 0.75 times of inner restrictive coating thickness.
Beneficial effect: compared with prior art, colliery of the present utility model high flame retardant Plastic-sheathed Cable structure is comparatively simple, the setting of the screw thread of coupling mutually on inner restrictive coating and external sheath layer, the person of being easy to use is fixed in installation place for this cable and (is specially and the external sheath layer of cable is removed one section, be fixed on inner restrictive coating with the nut matched, or, the inner restrictive coating of cable is removed, be fixed with the bushing type helicitic texture of coupling), anti-interference layer is the setting of metal material, anti-interference barrier can be formed on the one hand, on the other hand, available protecting can be carried out to three of an inside conductor cores and packing material, the setting of rigid foam insert, effectively can fix the position of three conductor cores, in addition, foam insert is the material with certain hole, it can promote the heat radiation of conductor cores, in general, structure of the present utility model, there is good decay resistance, fire resistance and anti-combined stress performance, useful life is longer, convenient and practical, suitable further genralrlization application.
