Description

A kind of light-duty light conduits in underground
Technical field
The present invention relates to the light-duty light conduits of a kind of cable more particularly to a kind of underground.
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, light-weight, convenient in carrying the light-duty light conduits in underground.
The technical scheme is that the cable includes power transmission core, signal transmssion line core and control conductor, The power transmission core includes copper conductor, insulating layer, and the signal transmssion line core includes aluminium conductor, insulating layer, described Control conductor include tinned copper conductor, insulating layer, the power transmission core, signal transmssion line core, between control conductor It is provided with insulation filling, extrudes proof copper-wire braided shielding outside the power transmission core, signal transmssion line core, control conductor jointly Layer, the proof copper-wire braided shielded layer are provided with oversheath outside.
The insulating layer is crosslinked polyetylene insulated layer.
The insulation filling is ceramic insulating layer.
The oversheath is pe sheath.
The configuration of the present invention is simple, production cost be low, long service life, water-blocking moistureproof, corrosion-resistant, good mechanical property, weight Gently, convenient in carrying.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is conductor in figure, and 2 be insulating layer, and 3 be insulation filling, and 4 be proof copper-wire braided shielded layer, and 5 be oversheath.
Specific embodiment
