Abstract
The utility model discloses a medium-voltage movable shielding monitoring rubber jacketed extra-flexible cable for a coal mine. The cable is characterized by comprising a power line core and a monitoring line core; a power line core conductor in the power line core and a monitoring line core conductor in the monitoring line core are respectively formed by twisting and knitting a plurality of tin-plated copper wires; a wrapped or longitudinal semi-conductive cotton tape, a conductor extruded shielding layer, an ethylene-propylene rubber extruded insulation layer, an extruded insulation shielding layer and an outer shielding layer which is knitted by using tin-plated copper wires and is reinforced by fibers are arranged in sequence from inside to outside on the power line core conductor so as to form the power insulation core line; three power insulation line cores are twisted to forma cable core; and an extruded semi-conductive type inner sheath layer, three monitoring line core conductors which are 1200 degrees from each other, an extruded semi-conductive cotton tape and an extruded outer protective layer are arranged in sequence from inside to outside on the cable core. The cable is flexible, oil resistant, tearing resistant and excellent in mechanical property and electric property; and in particular, the underground production of the coal mine is kept safe due to flame retarding property.
Description
Technical field
The utility model relates to a kind of electrical equipment cable, relate in particular to a kind of New Coal Mine with in press mobile shielding to monitor rubber cover high flexible cable, belong to technical field of electric wires and cables.
Background technology
Along with economic development, demand for energy progressively increases, and rich coal resources in China within following considerable time, can not change take coal as main energy general layout, and therefore corresponding coal mine moving rubber sleeve flexible cable demand is larger.The 6-10kV moving metal shield monitor type rubber sleeve soft cable for coal mine is dispersed throughout each corner in colliery as a kind of essential coal industry field articles for use, be the cable of down-hole coal excavation area working face, be mainly used in the underground moving transformer of rated voltage 8.7/10kV and the power supply of similar devices and connect.Because the operational environment of cable is special, not only requires it to have good electric property, fire resistance, and will have higher resistance to bend(ing) energy.But the cable in the prior art can not meet the demands on useful life well, increases thus the replacing number of times of cable, reduces production efficiency, and increases potential safety hazard.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of softness, oil resistant, tear-proof are provided, have good mechanical performance and electrical property, good fire resistance presses mobile shielding supervision rubber to overlap high flexible cable during the colliery that can guarantee production safety under coal mine of long service life is used.
The utility model technical solution problem adopts following technical scheme:
The design feature of pressing mobile shielding supervision rubber to overlap high flexible cable during the colliery is used in the utility model is to have the power core and monitor core, and the pilot wire core conductor in the power line core conductor in the described power core and the supervision core is formed by the many stranded braidings of tinned copper wire respectively; Setting gradually from inside to outside wrapped or vertical bag semi-conductive cloth tape, conductor on described power line core conductor extrudes screen, ethylene-propylene rubber extruded insulation layer, extrudes the insulation screen that forms and consists of the power insulation core wire by tinned copper wire braiding and the outer shielding layer strengthened by fiber; Consist of cable core by three described power insulated wire cores twisted synthesizing cables, on described cable core, set gradually from inside to outside and extrude semiconductive type inner restrictive coating, three and be mutually pilot wire core conductor, the wrapped semi-conductive tapes that form of 120 degree and extrude the outer jacket that forms.
The design feature of pressing mobile shielding supervision rubber to overlap high flexible cable during the utility model colliery is used also is:
Described power line core conductor and pilot wire core conductor are the 6th class tinned copper wire and are the structure that tangles again.
Described outer jacket is take neoprene rubber, haloflex or polyester elastomer as material, and two-layer co-extrusion forms double-deck outer jacket.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model softness, oil resistant, tear-proof have good mechanical performance and electrical property, good fire resistance, and long service life can guarantee production safety under coal mine.
2, sheath material adopts the neoprene rubber in the utility model, or haloflex, polyester elastomer material, and its flexibility is good, and mechanical strength can reach 20MPa, and tear resistance is strong, prolongs cable useful life.Oxygen index reaches more than 35, meets every physical and mechanical properties of standard code and the requirement of every fire resistance.Adopt the double-decker of inner/outer sheath, prevent from effectively that cable is in use too much to be subject to mechanical damage and cable is wracked, avoided the frequent occurrence of down-hole accident.
