Abstract
The invention discloses a mining control cable, which comprises an insulating cable core, an inner sheath layer and an outer sheath layer, wherein the insulating cable core is formed by a single stranded conductor or a plurality of stranded conductors with extruded insulating layers; PP (propene polymer) rope filler is laid in a gap between the insulating cable core and a shielding layer in parallel; the inner side of the outer sheath layer is also provided with an armor layer. The mining control cable disclosed by the invention is novel in structure, and has a good shielding electric field and excellent properties of compression strength, tensile strength, fire resistance, water resistance, corrosion resistance, ageing resistance and the like.
Description
Technical field
The present invention relates to field of cables, be 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 ensure that raw coal can be supplied endlessly, the mining system in colliery, conveying system, ventilating system, the normal operation of drainage system, the quality of mining cable just seems very important, mining cable lays bad environments, geologic structure is complicated, and often need to pull and move, even rupture because stretching resistance and compressive resistance poor performance insulating barrier easily suffer to destroy, mine cannot be met to power normally needs, secondly common cable shielding properties is poor, can generate an electromagnetic field when cable is energized and form electrostatic around, in case of pernicious explosion accident often occurs high concentration gas.
Summary of the invention
The present invention 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 of the present invention comprises single following or some insulated core, inner restrictive coating and external sheath layers formed with the stranded conductor being extruded with insulating barrier, in space between insulating core cable and screen, parallel laid is provided with PP rope inserts, is also provided with armour inside external sheath layer.
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:
Novel structure of the present invention, has good electric field shielding, resistance to compression tension, fire resistant flame retardant, waterproof anti-corrosion, ageing-resistant excellent properties of Denging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, conductor 2, insulating barrier 3, PP restrict 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 the insulating core cable be wrapped in copper strip shielding layer 4, inner restrictive coating 5 and external sheath layer 7, it is characterized in that: in the space between insulating core cable and screen 4, parallel laid is provided with PP rope inserts 3, also be provided with armour 6 inside external sheath layer 7, armour 6 adopts zinc plated mild carbon steel silk; Described insulating core cable is made up of the stranded conductor 1 that three are extruded with insulating barrier 2; Conductor 1 is copper conductor; Insulating barrier 2 adopts poly-second propylene.
Novel structure of the present invention, has good electric field shielding, resistance to compression tension, fire resistant flame retardant, waterproof anti-corrosion, ageing-resistant excellent properties of Denging.
