Abstract

The utility model discloses an aluminum alloy conductor wire core insulated flexible cable, which is composed of aluminum alloy conductor wire cores, a polyperfluorinated ethylene propylene insulating layer, a low-smoke halogen-free polyolefin sheath layer, a polyvinyl chloride insulating layer and a nickel belt armor layer. The aluminum alloy conductor wire cores can be divided into three groups, the three groups of aluminum alloy conductor wire cores are coated with the polyperfluorinated ethylene propylene insulating layer, the polyperfluorinated ethylene propylene insulating layer is coated with the low-smoke halogen-free polyolefin sheath layer, the low-smoke halogen-free polyolefin sheath layer is coated with a polyvinyl chloride insulating layer, and each aluminum alloy conductor wire core is composed of an aluminum alloy conductor, an aluminum belt armor layer and a butyronitrile insulating layer. The aluminum alloy conductor wire core insulated flexible cable is light in weight and convenient in transportation, has high abrasion resistance, cold resistance, high temperature resistance, high oxidation resistance and high tensile strength, the maximum allowable operating environment temperature of the aluminum alloy conductor wire core insulated flexible cable is 95 DEG C, and the allowable bending radius of the aluminum alloy conductor wire core insulated flexible cable is 12 times the outer diameter of the cable.

Description

A kind of aluminium alloy conductor core insulated cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of aluminium alloy conductor core insulated 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 field such as computer, machine room, high and low temperature resistance to cable, pull resistance, cold-resistant high temperature resistant, non-oxidizability aspect require all high especially.

Utility model content

In order to overcome the defect of above-mentioned prior art, it is strong that the purpose of this utility model is to provide a kind of pull resistance, convenient transport, the aluminium alloy conductor core insulated cable cold-resistant high temperature resistant, non-oxidizability is strong.

The utility model takes following technical scheme to realize: a kind of aluminium alloy conductor core insulated cable, it is by aluminium alloy conductor core, perfluoroethylene-propylene insulating barrier, low-smoke halogen-free polyolefin restrictive coating, polyvinyl chloride insulation layer and nickel strap armour composition, described aluminium alloy conductor core has three groups, outside three group aluminum alloy conductor thread cores, wrap up one deck perfluoroethylene-propylene insulating barrier, outside described perfluoroethylene-propylene insulating barrier, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, outside described low-smoke halogen-free polyolefin restrictive coating, wrap up one deck polyvinyl chloride insulation layer, described aluminium alloy conductor core is by aluminium alloy conductor, aluminium strip armour and butyronitrile insulating barrier composition.

Between described aluminium strip armour and butyronitrile insulating barrier, be extruded with a copper metal hose.

Described nickel strap armour inside is extruded with a copper wire drainage thread.

The utlity model has in sum following beneficial effect: this kind of cable is lightweight, convenient transport, resistance to wear is strong, cold-resistant high temperature resistant, non-oxidizability is strong, and pull resistance is strong, it is 95 DEG C that this cable allows operational environment maximum temperature, the permission bending radius of this cable is the outside diameter of cable 12 times.
