Abstract
The utility model discloses a tensile cabtyre flexible cable for a coal mine. The tensile cabtyre flexible cable comprises three power wire core conductors and a grounding wire core conductor; the three power wire core conductors are externally packaged with an insulating layer and a shielding layer respectively in sequence; the grounding wire core conductor is externally packaged with an insulating layer; the three power wire core conductors packaged with the shielding layers and the grounding wire core conductor packaged with the insulating layer are longitudinally placed in parallel by using a filling core as a center to form a cable core; a jacket layer is formed outside the cable core in an extrusion molding way; an elastic rope made of an elastic body material is arranged between the jacket layer and the cable core; the cross section of the elastic rope is fan-shaped; and a fiber rope with a fan-shaped cross section is arranged in the center of the elastic rope. The tensile cabtyre flexible cable is good in electrical conductivity; the enough insulating strength exists between wire cores; a short circuit failure is not easy to occur; meanwhile, the elastic rope is arranged between the jacket layer and the cable core of the cable; the tensile property of the cable is promoted to a novel level; in addition, the cable further has compression resistance, wear resistance and flame resistance performance; the shielding layers are better in shielding effect; the stripping is easy; and a joint of the cable is easy to manufacture.
Description
Technical field:
The utility model relates to the mining cable technical field, relates in particular to a kind of colliery and uses the tensile type rubber sleeve flexible cable.
Background technology:
Mining cable is meant that ground installation and underground equipment that coal mining is industrial use the electric wire cable product.Use cable comprising coal-winning machine, transporter, communication, illumination and signalling arrangement, and the electric drill cable, the feed cable that cap lamp electric wire and mobile substation, down-hole are used etc.
MY-0.38/0.66kV, MYP-0.38/0.66kV and MYP-0.66/1.14kV colliery be with moving the mining flame-retardant cable that rubber sleeve flexible cable is People's Republic of China's coal industry (unification) design, and product is used for that rated voltage is the power supply connection that coal excavation apparatus is moved in 0.38/0.66kV or the various down-holes of 0.66/1.14kV under the coal mine.
Original mining cable in actual use, tensile strength can not satisfy the demand of actual working environment fully, does not have enough dielectric strengths between power core and the ground connection core, is prone to defectives such as failed because.
The utility model content:
To the deficiency of prior art, the purpose of the utility model provides a kind of colliery and uses the tensile type rubber sleeve flexible cable, and the structural design advantages of simple has promoted the overall performance of cable.
The technical scheme of the utility model is following:
The tensile type rubber sleeve flexible cable is used in the colliery; Comprise three power line core conductors, earth connection core conductor; It is characterized in that: described three power line core conductors are enclosed with insulating barrier, screen outward respectively successively; Described earth connection core conductor is wrapped with insulating barrier, and three power line core conductors of parcel screen are the parallel formation cable core of putting of central longitudinal with the filled core with the earth connection core conductor of wrap insulate layer, and the outer extrusion moulding of cable core has restrictive coating; Be provided with the cross section between restrictive coating and the cable core and be the elastic threads of fan-shaped elastomeric material, it is fan-shaped cordage that the elastic threads center is provided with the cross section.
The tensile type rubber sleeve flexible cable is used in described colliery, it is characterized in that: described screen adopts semiconductive material to extrude or wrapped formation, and the volume resistance of screen is controlled at 10
2～10
4In the Ω cm scope.
The utility model has the advantages that:
The colliery of the utility model conducts electricity very well with the tensile type rubber sleeve flexible cable; Enough dielectric strengths are arranged between the core; Be difficult for outside the failed because, simultaneously, be provided with elastic threads between cable cover(ing) layer and the cable core; The tensile property of cable is risen to new height, and this outer cable also has resistance to compression, wear-resisting and fire resistance; Screen adopts and extrudes or wrapped structure, makes electric field balanced, the better effects if of shielding, and the volume resistance of semi-conductive layer is controlled at 10
2～10
4In the Ω cm scope, outer conducting layer is prone to peel off, and is convenient to make cable joint.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The tensile type rubber sleeve flexible cable is used in the colliery; Comprise three power line core conductors 1, earth connection core conductor 2; Three power line core conductor 1 outer insulating barrier 3, screens 4 of being enclosed with successively respectively; Earth connection core conductor 2 is wrapped with insulating barrier 3, and three power line core conductors 1 of parcel screen 4 are the parallel formation cable core of putting of central longitudinal with the earth connection core conductor 2 of wrap insulate layer 3 with filled core 5, and cable core extrusion moulding outward has restrictive coating 6; Be provided with the cross section between restrictive coating 6 and the cable core and be the elastic threads 7 of fan-shaped elastomeric material, it is fan-shaped cordage 8 that elastic threads 7 centers are provided with the cross section.
