Description
Technical field
The present invention relates to a kind of power cable more particularly to a kind of mine coal cutter power cables.
Background technique
Cable for the higher occasion of explosion-proof, waterproof performance requirement can normal transmission electric energy in the case where special become occurs
Be it is particularly important, since Sefe antiexplosion circuit distributing system and automatic detection control system use occasion are special, this
Require cable that must have resistance waterproof anti-explosion and interference free performance, requirement, which is otherwise not achieved, will make equipment generate malfunction
Or cause fire explosion, heavy losses are caused to the lives and properties of the country and people.
Summary of the invention
The present invention provide in order to solve problem above a kind of structure is simple, production cost is low, long service life, block water it is anti-
Damp, corrosion-resistant, good mechanical property mine coal cutter power cable.
The technical scheme is that the power cable includes three electric power cores, the electric power core includes
Shielded layer is arranged outside the conductor for conductor, shielded layer, insulating layer, is arranged insulating layer outside the shielded layer, and described three
It is equipped with insulation filling between electric power core, extrudes fire-retardant twining package tape outside three electric power cores jointly and constitutes cable core, it is described
Cable core outside inner sheath is set, metal armor layers are set outside the inner sheath, oversheath is set outside the metal armor layers.
The shielded layer is alloy-steel wire woven shield.
The insulating layer is crosslinked polyetylene insulated layer.
The insulation filling is ceramic insulating layer.
The inner sheath and oversheath is pvc sheath.
The metal armor layers are two-sided steel-tape armouring layer.
The configuration of the present invention is simple, production cost be low, long service life, water-blocking moistureproof, corrosion-resistant, good mechanical property.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is conductor in figure, and 2 be shielded layer, and 3 be insulating layer, and 4 be insulation filling, and 5 be fire-retardant twining package tape, and 6 be inner sheath, 7
It is metal armor layers, 8 be oversheath.
Specific embodiment
A kind of mine coal cutter power cable, the power cable include three electric power cores, the electric power core
Including conductor 1, shielded layer 2, insulating layer 3, shielded layer 2 is set outside the conductor 1, insulating layer is set outside the shielded layer 2
3, it is equipped with insulation filling 4 between three electric power cores, extrudes fire-retardant twining package tape 5 outside three electric power cores jointly
Cable core is constituted, inner sheath 6 is set outside the cable core, metal armor layers 7, the metal armour are set outside the inner sheath 6
It fills and oversheath 8 is set outside layer 7.
The shielded layer 2 is alloy-steel wire woven shield.
The insulating layer 3 is crosslinked polyetylene insulated layer.
The insulation filling 4 is ceramic insulating layer.
The inner sheath 6 and oversheath 8 is pvc sheath.
The metal armor layers 7 are two-sided steel-tape armouring layer.
