Abstract

The utility model discloses a nickel-conductor-wire-core armored insulating flexible cable which includes three nickel-conductor wire cores, a fluorinated ethylene propylene insulating layer, a low-smoke halogen-free polyolefin sheath layer, a polyvinyl chloride insulating layer and an aluminum-strap armor layer. The three nickel-conductor wire cores are wrapped with a layer of fluorinated ethylene propylene insulating layer at the outside. The fluorinated ethylene propylene insulating layer is wrapped with a layer of low-smoke halogen-free polyolefin sheath layer at the outside. The low-smoke halogen-free polyolefin sheath layer is wrapped with a layer of polyvinyl chloride insulating layer at the outside. Each nickel-conductor wire core includes a nickel conductor, an aluminum-strap armor layer and a butyronitrile insulating layer. The cable is light in weight, convenient to transport, high in wear resistance, cold resistant and high-temperature resistant, high in inoxidizability and high in tensile strength; the cable allows the highest temperature of a work environment to reach 95 DEG C; and the allowed bending radius of the cable is 12 times of the outer diameter of the cable.

Description

A kind of nickel conductor thread core armouring insulated cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of nickel conductor thread core armouring 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 nickel conductor thread core armouring insulated cable cold-resistant high temperature resistant, non-oxidizability is strong.

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

Between described aluminium strip armour and butyronitrile insulating barrier, be extruded with an aluminum metal flexible pipe.

Described aluminium strip armour inside is extruded with an aluminium 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.
