Abstract
A kind of mine control cable, comprise single following or some insulation cable core, inner restrictive coating and external sheath layer with being extruded with the stranded conductor formation of insulating barrier, in space between insulating core cable and screen, parallel laid is provided with PP rope inserts, and external sheath layer inner side is also provided with armour.The utility model novel structure, has good electric field shielding, resistance to compression tension, fire resistant flame retardant, and waterproof is corrosion-resistant, ageing-resistant waits excellent properties.
Description
Technical field
The utility model relates to field of cables, is specifically related to a kind of mine control cable.
Background technology
Since the 18 Century European industrial revolution, coal is the important energy in the whole world always, the electric power resource of China 70% also comes from fire coal, in order to guarantee raw coal, can supply endlessly, the mining system in colliery, conveying system, ventilating system, the normal operation of drainage system, it is very important that the quality of mining cable just seems, it is severe that mining cable lays environment, geologic structure is complicated, and often need to pull and move, because stretching resistance and the poor insulating barrier of compressive resistance performance easily suffer to destroy even fracture, cannot meet the mine needs of powering normally, secondly common cable shielding properties is poor, when cable is switched on, can generate an electromagnetic field and form around static, in case of high concentration gas tends to occur pernicious explosion accident.
Utility model content
The utility model will provide a kind of waterproof antiwear, the mine control cable that ageing-resistant, shielding properties is good.
Technical scheme
For solving the problems of the technologies described above, mine control cable described in the utility model comprises single following or some insulation cable core, inner restrictive coating and external sheath layer with being extruded with the stranded conductor formation of insulating barrier, in space between insulating core cable and screen, parallel laid is provided with PP rope inserts, and external sheath layer inner side is also provided with armour.
Described insulating barrier adopts poly-second propylene or solubility polytetrafluoroethylmaterial material, and it can make the long-term maximum operating temperature of conductor can reach 200 degree.
Described conductor is copper conductor or tinned copper conductor.
Described armour adopts zinc plated mild carbon steel silk, and steel wire diameter is 3 ± 0.2mm,
Beneficial effect:
The utility model novel structure, has good electric field shielding, resistance to compression tension, fire resistant flame retardant, and waterproof is corrosion-resistant, ageing-resistant waits excellent properties.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, conductor 2, insulating barrier 3, PP rope inserts 4, copper strip shielding layer 5, inner restrictive coating 6, armour 7, external sheath layer
Specific embodiment
A kind of mine control cable, it comprises insulating core cable, inner restrictive coating 5 and the external sheath layer 7 being wrapped in copper strip shielding layer 4, it is characterized in that: in the space between insulating core cable and screen 4, parallel laid is provided with PP rope inserts 3, external sheath layer 7 inner sides are also provided with armour 6, and armour 6 adopts zinc plated mild carbon steel silk; Described insulating core cable consists of three stranded conductors 1 that are extruded with insulating barrier 2; Conductor 1 is copper conductor; Insulating barrier 2 adopts poly-second propylene.
The utility model novel structure, has good electric field shielding, resistance to compression tension, fire resistant flame retardant, and waterproof is corrosion-resistant, ageing-resistant waits excellent properties.
