Abstract
A kind of geothermal energy cable, relates to a kind of geothermal energy cable.This utility model includes cable core, is orderly arranged outside each glass fibre high fire-retardance twining package tape, double-deck water blocking tape layer, 105 DEG C of fire-retardant inner liners, braiding armor, electronics non-woven fabrics lapping layer, halogen-free environment-friendly type polyolefin sheath layer, ripple aluminium strip overcoat and equadag coating at cable core；Between cable core and glass fibre high fire-retardance twining package tape, glass fibre gasket for packing is set；Cable core includes much the most stranded insulated wire cores, and every insulated wire cores includes bundle strand conductor respectively, at the bundle strand centrally disposed waterproof yarn of conductor, is orderly arranged outside each burning ceramics belt and polyurethane elastomer insulating barrier at bundle strand conductor；Braiding armor is mutually woven by many rustless steel finer wires and Duo Gen tinned copper wire and forms.This utility model is simple and reasonable, tensile strength is high, high temperature resistant, oil resistant, corrosion-resistant, environmental protection, good waterproof performance, it is adaptable to during the supporting electric wire of geothermal energy correlation engineering uses.
Description
Technical field
This utility model relates to a kind of geothermal energy cable, is mainly used in electric power transmission special cable after geothermal energy converting electrical energy.
Background technology
China is the country that geothermal energy resources are abundant, and geothermal energy resources account for the 7.9% of the whole world, the wide resource nationwide that high-temperature geothermal resource compares.The most traditional resource will be exhausted, novel energy by greatly developing, for sustainable development, strengthen alternative energy source and the research and development of regenerative resource, the development promoting new forms of energy is not only conformed with the trend of world energy sources, the demand that the present stage energy industry structure optimization of Ye Shi China adjusts, geothermal energy development prospect will be the most wide, but can not meet the requirement carrying electric energy by the supporting electric wire of geothermal energy correlation engineering therewith.By existing national standards produce cable can not contentedly heat energy with mainly have following some: 1. conductor tensile strength is not, and conductor is non-watertight.2. insulant is the most aging, non-refractory, not oil resistant, be weak to burn into not anti-extrusion, burning after to produce a large amount of toxic gas, resistance to ambient temperature low.3. packing material is the most fire-retardant, non-watertight, do not block water.4. overcoat easily rupturable water inlet during mounting and installation, becomes rusty on armor after water inlet, and etching insulative causes and punctures.Antibiont destructive power is the strongest.5. cable entirety tensile strength is inadequate, and cable due to geological transformation, destroys cable internal structure after laying, and easily causes cable short circuit.According to above-mentioned situation it is necessary to have the coincidently heat energy cable of this characteristic, the requirement of engineering can be met.
Utility model content
This utility model purpose is for problem above, it is provided that a kind of tensile strength is high, high temperature resistant, oil resistant, corrosion-resistant, environmental protection, the geothermal energy cable of good waterproof performance.
This utility model includes cable core, is orderly arranged outside each glass fibre high fire-retardance twining package tape, double-deck water blocking tape layer, 105 DEG C of fire-retardant inner liners, braiding armor, electronics non-woven fabrics lapping layer, halogen-free environment-friendly type polyolefin sheath layer, ripple aluminium strip overcoat and equadag coating at described cable core；Between described cable core and glass fibre high fire-retardance twining package tape, glass fibre gasket for packing is set；Described cable core includes much the most stranded insulated wire cores, and every insulated wire cores includes bundle strand conductor respectively, at the described bundle strand centrally disposed waterproof yarn of conductor, is orderly arranged outside each burning ceramics belt and polyurethane elastomer insulating barrier at described bundle strand conductor；Described braiding armor is mutually woven by many rustless steel finer wires and Duo Gen tinned copper wire and forms.
This utility model uses burning ceramics band to be Novel fireproof material, high temperature resistant reach that (800 DEG C) can effectively protect due to the too high Damage to insulation of conductor temperature and conductor self melted；Using glass fibre gasket for packing, this material environment resistant temperature high (more than 200 DEG C), high fire-retardance, smokeless after burning, tasteless, suppleness is high, can effectively improve cable overall flame；Use rustless steel finer wire braiding armouring; it is greatly improved cable tensile strength and roundness; it is easy to the built on stilts of cable lay and cable installation in pipe; it is effectively protected cable core and insulating barrier succeeding stretch affects electrical property and insulating properties; and add corresponding tinned copper wire, to ensure can pass through under cable breakdown state leakage current during braiding.This utility model is simple and reasonable, tensile strength is high, high temperature resistant, oil resistant, corrosion-resistant, environmental protection, good waterproof performance, it is adaptable to during the supporting electric wire of geothermal energy correlation engineering uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, this utility model includes cable core, is orderly arranged outside each glass fibre high fire-retardance twining package tape 1, double-deck 2,105 DEG C of fire-retardant inner liners 3 of water blocking tape layer, braiding armor 4, electronics non-woven fabrics lapping layer 5, halogen-free environment-friendly type polyolefin sheath layer 6, ripple aluminium strip overcoat 7 and equadag coating 8 at cable core；Between cable core and glass fibre high fire-retardance twining package tape 1, glass fibre gasket for packing 9 is set；Cable core includes much the most stranded insulated wire cores 10, and every insulated wire cores 10 includes bundle strand conductor 11 respectively, at the bundle strand centrally disposed waterproof yarn 12 of conductor 11, is orderly arranged outside each burning ceramics belt 13 and polyurethane elastomer insulating barrier 14 at bundle strand conductor 11；Braiding armor 4 is mutually woven by many rustless steel finer wires 15 and Duo Gen tinned copper wire 16 and forms.
