Abstract
The utility model discloses a coal mine electric drill cable, which comprises a plurality of power line core conductors, a control line core conductor and a ground connection line core conductor. The plurality of power line core conductors and the control line core conductor are respectively wrapped by insulation layers. The plurality of power line core conductors wrapped by the insulation layers are respectively wrapped by semiconductor shielding layers and fireproof layers, the ground connection line core conductor is wrapped by a lapping layer, the ground connection line core conductor wrapped by the lapping layer, the plurality of the power line core conductors wrapped by fireproof layers and the control line core conductor wrapped by the insulation layer are mutually twisted with a filler core as the center to form a cable core, a star-shaped pulling resistant rope is arranged in the filler core, and a sheath layer is extruded to be formed outside the cable core. The coal mine electric drill cable is reasonable in structural design, the fireproof layer is additionally positioned outside the insulation of the power line core conductor, simultaneously the star-shaped pulling resistant rope is arranged in the center of the cable core, fireproof performance, structural compactness and drag resistance of the cable are improved, and requirements for practical work environment are met.
Description
Technical field:
The utility model relates to mining cable, relates in particular to a kind of colliery and uses the electric drill cable.
Background technology:
Along with developing rapidly of Chinese national economy and improving constantly of living standards of the people, the requirement of quickening city special purpose power grid construction is urgent day by day.The people that make that cause fire incident because of cable press for a kind of special cable that can tackle strong fire damage capability of development.For the higher cable use occasion of fire protection requirement; The level of common in the past organic material fire-resisting cable exists tangible incompatibility, so national correlation department such as the Fire-Fighting Bureau under the Ministry of Public Security and other enterprises and institutions put on planning to the high performance fire-resisting cable of development for a long time.
MZ-0.3/0.5kV uses in the colliery electric drill Plastic-sheathed Cable, is People's Republic of China's coal industry (unification) design mining flame-retardant cable product, is used for the electric power connection line of rated voltage 0.3/0.5kV and following electric drill under the coal mine.
Pull demand that performance do not reach actual working environment with the fire protecting performance of electric drill Plastic-sheathed Cable and structural compactness with anti-for the MZ-0.3/0.5kV colliery of original design.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of colliery and uses the electric drill cable, and the structural design advantages of simple effectively raises the fireproofing of cable performance and reaches structural compactness and the anti-performance that pulls.
The technical scheme of the utility model is following:
The electric drill cable is used in the colliery; Comprise several power line core conductors, control line core conductor, earth connection core conductor; It is characterized in that: described several power line core conductors, control line core conductor are enclosed with insulating barrier outward respectively; Several power line core conductors of wrap insulate layer are enclosed with semiconductive shielding layer, fireprotection layer outward respectively, and described earth connection core conductor is wrapped with lapping layer, and the earth connection core conductor of parcel lapping layer is that the mutual stranded bunchy in center constitutes cable core with the filled core with the control line core conductor of several power line core conductors of parcel fireprotection layer, wrap insulate layer; Be provided with the tension rope of star in the described filled core, the outer extrusion moulding restrictive coating of cable core.
