Abstract

Disclosed is a mobile rubber flexible cable for coal mine, comprising a tinning soft copper conductor, a conductor shielding layer, an insulating layer, an insulation shielding layer, a semi-conductive band taped covering, a tin-coated copper filament braid ply, a cable core, an inner sheath, an internal layer semi-conductive strap, a supervision wire core, an external layer semi-conductive strap, and an oversheath, wherein the tinning soft copper conductor is evenly extruded with a conductor shielding layer, an insulating layer, and an insulating shield layer in a three-layer co-extrusion manner; the exterior of the insulation shielding layer is coated with a semi-conductive band taped covering; the semi-conductive band taped covering is coated with a tin-coated copper filament braid ply via braiding to form the wire core; multiple wire cores are twisted to form a cable core; the cable core is provided with an inner sheath via extrusion; the inner sheath is wrapped by the internal layer semi-conduction strap and an external layer semi-conduction strap; the supervision wire core is vertically arranged between the internal layer semi-conductive strap and the external layer semi-conductive strap; and the external layer semi-conductive strap is provided with the oversheath via extrusion.

Description

The coal mine moving rubber sleeve flexible cable
Technical field
The utility model relates to technical field of electric wires and cables, and particularly the Coal Electricity cable is specially a kind of coal mine moving rubber sleeve flexible cable.
Background technology
At present, cloth shape second the third Insulation Material is all adopted in the insulation of coal mine moving Plastic-sheathed Cable.Such Insulation Material is too much because of the interleaving agent that uses in the insulating material course of processing, and insulation extrudes and is difficult in the process mixing, and causes electrical property, bad mechanical property, can not satisfy high electrical, jumbo requirement.
Summary of the invention
The purpose of this utility model provides a kind of high electrical performance, high-mechanical property, high flame resistance and the large capacity rubber sleeve flexible cable of 8.7/10kV coal mine moving capacious, is specially a kind of coal mine moving rubber sleeve flexible cable.
The technical solution of the utility model is: a kind of coal mine moving rubber sleeve flexible cable.It comprises zinc-plated soft copper conductor, conductor shield, insulating barrier, insulation screen, semi-conductive tape lapping layer, tincopper fuse wire braided armor, core, cable core, inner sheath, internal layer semi-conductive cloth tape, supervision core and outer semi-conductive cloth tape, oversheath.
Adopt three-layer co-extruded mode evenly to extrude conductor shield, insulating barrier and insulation screen at zinc-plated soft copper conductor.At the peripheral wrapped one deck semi-conductive tape lapping layer of insulation screen.Form core at semi-conductive tape lapping layer braiding one deck tincopper fuse wire braided armor.Many cores are twisted into cable core.Extrude inner sheath at cable core.Wrapped internal layer semi-conductive cloth tape and outer semi-conductive cloth tape on inner sheath.Between internal layer semi-conductive cloth tape and outer semi-conductive cloth tape, vertically place and monitor core.Extrude oversheath at outer semi-conductive cloth tape.
Described conductor shield and insulation screen are all selected cross-linking type EVA material, and this insulated with material resistance is little.Insulating barrier is selected and is pressed the ethylene-propylene rubber granular materials in the high electrical performance, and this material has high electrical performance and high-mechanical property.Press the ethylene-propylene rubber granular materials in conjunction with tight in cross-linking type EVA material and the high electrical performance.Wherein insulation screen is peelable insulation shielding material.
Described inner sheath and oversheath are all selected high flame retardant rubber material, and this material has high flame resistance.
The utility model has the advantages that provides a kind of high electrical performance, high-mechanical property, high flame resistance and the large capacity rubber sleeve flexible cable of 8.7/10kV coal mine moving capacious.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of coal mine moving rubber sleeve flexible cable.
Among the figure: 1, zinc-plated soft copper conductor; 2, conductor shield; 3, insulating barrier; 4, insulation screen; 5, semi-conductive tape lapping layer; 6, tincopper fuse wire braided armor; 7, core; 8, cable core; 9, inner sheath; 10, internal layer semi-conductive cloth tape; 11, monitor core; 12, outer semi-conductive cloth tape; 13, oversheath.
