Abstract
The invention discloses a solid polyvinyl chloride insulation radio frequency cable. The solid polyvinyl chloride insulation radio frequency cable is composed of aluminum alloy cable cores, nickel cable cores, a polyvinyl chloride insulation layer, a copper strip shielding layer, an aluminum strip armor layer, a chloroprene rubber sheath and copper cable cores. The aluminum alloy cable cores are wrapped by the polyvinyl chloride insulation layer, the four nickel cable cores and the four copper cables cores are arranged in the polyvinyl chloride insulation layer at the same time in an extruded mode, the nickel cable cores and the copper cable cores are arranged at intervals, the copper strip shielding layer is arranged outside the polyvinyl chloride insulation layer in an extruded mode and the aluminum strip armor layer is arranged outside the copper strip shielding layer in an extruded mode. The solid polyvinyl chloride insulation radio frequency cable has the advantages of being resistant to flames, low in heat expansion coefficient, stable, not prone to being corroded by acid and alkali and resistant to heat.
Description
Technical field
The invention belongs to field of cables, be specifically related to a kind of real core PVC insulated radio frequency cable.
Background technology
At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the prescription of cable is the most constantly improved, the cable such as used in the fields such as aviation, boats and ships, electric power, fire-retardant, high temperature resistant, acid and alkali-resistance, environmental protection aspect and security reliability aspect to cable require the highest.
Summary of the invention
For overcoming the defect of prior art, it is an object of the invention to provide and a kind of there is high temperature resistant, the real core PVC insulated radio frequency cable of acid and alkali-resistance characteristic.
The present invention solves technical problem and adopts the following technical scheme that a kind of real core PVC insulated radio frequency cable, it is by aluminium alloy core, nickel wire core, polyvinyl chloride insulation layer, copper strip shielding layer, aluminium strip armor, chloroprene rubber sheath layer and copper core composition, described aluminium alloy core is wrapped with a strata vinyl chloride insulation layer, it is extruded with four nickel wire cores and four copper cores inside described polyvinyl chloride insulation layer simultaneously, nickel wire core is spaced with copper core, one layer of copper strip shielding layer it is extruded with outside described polyvinyl chloride insulation layer, one layer of aluminium strip armor it is extruded with outside described copper strip shielding layer.
Described aluminium alloy core is made up of aluminium alloy conductor and semiconductive shielding layer, butyronitrile insulating barrier and steel-tape armouring pe sheath layer outside being wrapped in aluminium alloy conductor successively.
Beneficial effects of the present invention is embodied in: the present invention is widely used in the fields such as aviation, boats and ships, electric power, uses polyvinyl chloride insulation layer, has fire-retardant, at the bottom of thermal coefficient of expansion, stable, is difficult to by acid, caustic corrosion, the advantage relatively tolerated ratio of specific heat；
Steel-tape armouring pe sheath has lightweight, lays the advantage not limited by drop.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, aluminium alloy core；2, nickel wire core；3, polyvinyl chloride insulation layer；4, copper strip shielding layer；5, aluminium strip armor；6, chloroprene rubber sheath layer；7, copper core.
Detailed description of the invention
As shown in Figure 1, a kind of real core PVC insulated radio frequency cable, it is by aluminium alloy core 1, nickel wire core 2, polyvinyl chloride insulation layer 3, copper strip shielding layer 4, aluminium strip armor 5, chloroprene rubber sheath layer 6 and copper core 7 form, described aluminium alloy core 1 is wrapped with a strata vinyl chloride insulation layer 3, described polyvinyl chloride insulation layer 3 is internal is extruded with four nickel wire cores 2 and four copper cores 7 simultaneously, nickel wire core 2 is spaced with copper core 7, one layer of copper strip shielding layer 4 it is extruded with outside described polyvinyl chloride insulation layer 3, one layer of aluminium strip armor 5 it is extruded with outside described copper strip shielding layer 4.
Detailed description of the invention: aluminium alloy core 1 is made up of aluminium alloy conductor and semiconductive shielding layer, butyronitrile insulating barrier and steel-tape armouring pe sheath layer outside being wrapped in aluminium alloy conductor successively.
This cable allows working environment maximum temperature to be 70 DEG C；Shielding rejection coefficient is less than 0.8.
The above is embodiments of the invention, therefore all equivalence changes done according to structure, feature and the principle described in the present patent application scope or modification, in the range of being all included in present patent application.
