Abstract

The utility model discloses a solid polyvinyl chloride (PVC) insulating radio frequency cable, which comprises an aluminum alloy cable core, nickel cable cores, a PVC insulating layer, a copper tape shielding layer, an aluminum tape armored layer, a chlorobutadiene rubber sheath layer and copper cable cores. The PVC insulating layer is wrapped outside the aluminum alloy cable core. Four nickel cable cores and four copper cable cores are simultaneously extruded inside the PVC insulating layer, wherein the nickel cable cores and the copper cable cores are arranged at intervals. The copper tape shielding layer is extruded outside the PVC insulating layer and the aluminum tape armored layer is extruded outside the copper tape shielding layer. The solid PVC insulating radio frequency cable is flame-retardant, low in thermal expansion coefficient, stable, acid and alkali corrosion resistant and thermal-resistant.

Description

A kind of real core PVC insulated radio frequency cable

Technical field

The utility model belongs to field of cables, is 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 quality requirement of cable is also constantly improved, such as the cable using 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 all high especially.

Utility model content

For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of real core PVC insulated radio frequency cable high temperature resistant, acid and alkali-resistance characteristic that has.

The utility model technical solution problem adopts following technical scheme: 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 armour, chloroprene rubber sheath layer and copper core composition, described aluminium alloy core is wrapped with one deck polyvinyl chloride insulation layer, described polyvinyl chloride insulation layer inside is extruded with four nickel wire cores and four copper cores simultaneously, nickel wire core and copper core are spaced, described polyvinyl chloride insulation layer is extruded with one deck copper strips screen outward, described copper strip shielding layer is extruded with one deck aluminium strip armour outward.

Described aluminium alloy core by aluminium alloy conductor and the semiconductive shielding layer, butyronitrile insulating barrier and the steel-tape armouring pe sheath layer that are wrapped in successively outside aluminium alloy conductor form.

The beneficial effects of the utility model are embodied in: the utility model is widely used in the fields such as aviation, boats and ships, electric power, adopt polyvinyl chloride insulation layer, have fire-retardant, at the bottom of thermal coefficient of expansion, stable, difficult by acid, caustic corrosion, the advantage that ratio of specific heat is tolerated;

Steel-tape armouring pe sheath has lightweight, lays the advantage that is not subject to drop restriction.
