Description
Technical field
The utility model belongs to power cable technical field, is specifically related to the anticorrosive Weaving type cable of a kind of mining flame-retardant.
Background technology
At present along with coal mine machinery, automaticity improve constantly, electronic control technology has very important meaning in colliery.Cable is mainly made up of polyvinyl chloride oversheath, people is suffocated because polyvinyl chloride insulation and polyvinyl chloride oversheath very easily burn and can produce a large amount of hydrogen chloride toxic gases and die, therefore existing colliery control flexible cable is difficult to adapt to downhole safety requirement.Simultaneously mining cable when vertical layings for going into the well due to the overweight Long-Time Service of cable self after can deform or tear, when energising, breaking part easily can produce spark, thus causes great potential safety hazard; Moreover existing flexible cable metal screen layer often adopts iron wire to work out formation, be easily oxidized in the environment being in dark humidity for a long time, get rusty, affect its shield effectiveness.
Therefore, how improving the anti-flammability of cable, pull resistance and corrosion resistance, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The utility model provides the anticorrosive Weaving type cable of a kind of mining flame-retardant, has good anti-flammability, pull resistance and anticorrosive property, and reduces the harm caused environment.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the anticorrosive Weaving type cable of a kind of mining flame-retardant, comprise cable core and be coated on the protective jacket outside described cable core, described cable core is the conductor that some electric units are intertwined, described electric unit comprises metal bare wire and is coated on the ethylene propylene rubber insulated layer outside described metal bare wire, and described protective jacket comprises Merlon sheath, braid and mica lapping layer from outside to inside.Adopt Merlon as the outer protective sleeve of protective sleeve, there is good anti-flammability, pull resistance and anticorrosive property.Braid is fiber braiding layer, effectively prevents the oxidation of down-hole, and has fire-retardant effect.Adopt ethylene propylene rubber insulated layer coated metal bare wire, there is higher fusing point and good anti-flammability, and there is good shield effectiveness.
Preferably, described cable core inside is provided with fire-proof heat-insulating reinforcement.Be conducive to the Long-Time Service of down-hole vertical-rise cable, do not allow it be out of shape and tear.
Preferably, described fire-proof heat-insulating reinforcement is glass fibre belt.Glass fiber tape adopts high-temperature-resistant high type glass fibre, processes through special process.There is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, the feature such as weatherability, high strength, smooth in appearance.Spun-glass insulation heat insulating belt, silicon rubber glass fibre is mainly divided into protect heat insulating belt, glass radiation proof heat-preserving heat-insulating belt etc.
Preferably, described Merlon sheath is high-purity talc fire-retardant polycarbonate sheath.High-purity talc fire-retardant polycarbonate has excellent heat resistance, shock resistance, and fire-retardant BI level, has good mechanical performance in common serviceability temperature.Compared with the polymethyl methacrylate that performance is close, the impact resistance of Merlon is better, and refractive index is higher, and processing characteristics is better.
Preferably, described mica lapping layer is fireproof mica lapping layer.
The utility model discloses the anticorrosive Weaving type cable of a kind of mining flame-retardant, adopt Merlon as the outer protective sleeve of protective sleeve, there is good anti-flammability, pull resistance and anticorrosive property.Braid is fiber braiding layer, effectively prevents the oxidation of down-hole, and has fire-retardant effect.Adopt ethylene propylene rubber insulated layer coated metal bare wire, there is higher fusing point and good anti-flammability, and there is good shield effectiveness.Cable core inside is provided with fire-proof heat-insulating reinforcement, is conducive to the Long-Time Service of down-hole vertical-rise cable, does not allow it be out of shape and tears.
