Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.
At present, the cable on market is various, and they are applied in various different occasion.But most of cable all exists some problems, and such as insulation effect is poor, and useful life is short, and manufacturing cost is high, bulk strength is not high.
Summary of the invention
Goal of the invention: the purpose of this utility model is that provide one to conduct electricity very well, bulk strength is high in order to overcome deficiency of the prior art, can constantly work for a long time, safe and reliable, the reinforced polyvinyl chloride insulation control cables of long service life.
Technical scheme: in order to solve the problems of the technologies described above, the reinforced polyvinyl chloride insulation control cables of one described in the utility model, it comprises the conductor be combined into by oxygen-free copper wire harness and aramid fiber skein silk, insulating barrier is provided with in described conductor outside, screen is provided with in described insulating barrier outside, described conductor, insulating barrier and screen composition conductive unit, described conductive unit is provided with two, described in two, conductive unit is outside tangent is provided with strengthening core, packed layer is provided with at described conductive unit and strengthening core outside, the first lapping layer is provided with in described packed layer outside, proof copper-wire braided layer is provided with in described first lapping layer outside, the second lapping layer is provided with in described proof copper-wire braided layer outside, external sheath layer is provided with in described second lapping layer outside, they form cable body, described conductive unit diameter accounts for 1/3 of cable body diameter.
Described insulating barrier and external sheath layer are all polyvinyl chloride layer.
Described packed layer is composite material of silicon carbide packed layer.
Described first lapping layer and the second lapping layer are all nonwoven fabrics lapping layer.
Described proof copper-wire braided layer forms according to 11 vertical woven that changes.
The thickness of described insulating barrier is between 0.6-1.0mm.
The thickness of described external sheath layer is between 1.2-1.8mm.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure arranges rationally, adopt oxygen-free copper wire harness and aramid fiber silk composition conductor, allow aramid fiber silk to carry some power, the stressed of conductor copper wire can be reduced, improve tension and the bending resistance of conductor, and oxygen-free copper wire harness, compare fine copper, fine aluminium cable is more stable, conductivity is higher, adopt the insulating barrier between 0.6-1.0mm, good insulation effect can be played, adopt strengthening core, the intensity of effective raising cable, adopt proof copper-wire braided layer, the bulk strength of further raising cable, adopt composite material of silicon carbide packed layer, filling effect is good, the external sheath layer between 1.2-1.8mm is adopted to play a very good protection, improve product useful life, make it not fragile, adopt two-layer lapping layer, make integrated connection tightr, described conductive unit diameter accounts for 1/3 of cable body diameter, again by each layer with the use of, conductive unit runs the most reliable, result of use is the most desirable, this cable can constantly work for a long time, whole service life is longer, realistic instructions for use.
