Abstract
The utility model discloses an use power cable in pit, it includes thread core and polyethylene rubber sheath, it still is in including wrapping up in proper order silicone rubber insulating layer, the nylon non -woven fabrics in the thread core outside wind the covering, the thread core is three groups, and even crowded package is in inside the silicone rubber insulating layer, the thread core comprises copper conductor and fluorubber insulating layer, the aluminium foil weaving layer of parcel outside the copper conductor, the nylon non -woven fabrics is around the inside piece -root grafting ground sinle silk that still wraps up of covering, the nylon non -woven fabrics around the covering with be equipped with nickel plating copper wire woven shield between the polyethylene rubber sheath. This kind of cable electric conductive property is good, resistant draging, and anti broken string, it is high temperature resistant, mainly be applied to in the pit, waterproof moisture resistance, the shielding is high, and the antidetonation is moved.
Description
Technical field
The utility model designs a kind of power cable, particularly relates to a kind of down-hole power cable.
Background technology
At present, along with socioeconomic development, cable consumption increases rapidly, also constantly improves the quality requirement of cable.Such as in the exploitation work of coal mine, due to factors such as down-hole darkness and the long-term humidities of operational environment, traditional cable cannot meet the requirement of real work.
In view of the defect existed in above prior art, be necessary it to improve further, make it have more standby practicality, just can meet the actual service condition of cable.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of down-hole power cable with fire-retardant, high temperature resistant, waterproof oil resistant, the advantage such as anti-interference.
The utility model is taked following technical scheme to realize: a kind of down-hole power cable, it comprises master core and polyethylene rubber sheath, it also comprises the silicone rubber insulation layer be wrapped in successively outside described master core, nylon nonwoven fabrics lapping layer, described master core is three groups, evenly be extruded in described silicone rubber insulation layer inner, described master core is by copper conductor and the fluorubber insulating barrier that is wrapped in outside copper conductor, aluminium foil braid forms, described copper conductor is the zinc-plated ultra-fine soft copper tow strand of employing 99.9999% anaerobic annealing, a ground connection core is also wrapped up in described nylon nonwoven fabrics lapping layer inside, nickel plating copper wire woven shield is provided with between described nylon nonwoven fabrics lapping layer and described polyethylene rubber sheath.
Further, the fluorubber insulating barrier inside of described master core is provided with an aluminium wire heater wire.
Further, described ground connection core be by the annealed copper aluminum-alloy wire of electroplate up and down overlapping 270 ° of stranded braidings to the right form.
The utility model has following beneficial effect in sum: this kind of cable conduction performance is good, resistance to towing, resistance to winding, and anti-broken string is weather-proof high temperature resistant, and be mainly used in down-hole, waterproof is moisture resistance, and shielding is high, anti-vibration.
