Abstract

The utility model discloses an aluminum-alloy drainage-wire cable with a metal flexible pipe. The cable includes an aluminum metal flexible pipe, a polyester fiber layer, a tinned-aluminum-strip armor layer, a nickel-strip shielding layer, a fluorinated ethylene propylene insulating layer, a butyronitrile insulating layer and copper conductors. The aluminum metal flexible pipe is wrapped with a layer of polyester fiber layer at the outside. The polyester fiber layer is wrapped with a layer of tinned-aluminum-strip armor layer at the outside. The tinned-aluminum-strip armor layer is wrapped with a layer of nickel-strip shielding layer at the outside. The nickel-strip shielding layer is wrapped with a layer of fluorinated ethylene propylene insulating layer at the outside. The cable is light in weight, convenient to transport and high in wear resistance, tear resistance and aging resistance. The cable allows the highest temperature of a work environment to be 90 DEG C. The allowed bending radius of the cable is 12 times of the outer diameter of the cable.

Description

A kind of band metal hose aluminium alloy drainage thread cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of band metal hose aluminium alloy drainage thread cable.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, and the quality requirement of cable is also constantly improved, such as the cable using in the fields such as mining site, power plant and metallurgy, the resistance to wear to cable, anti-tear drawing property, ageing resistance aspect require all high especially.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of lightweight, convenient transport, the band metal hose aluminium alloy drainage thread cable that anti-tear drawing property is strong, ageing resistance is strong.

The utility model takes following technical scheme to realize: a kind of band metal hose aluminium alloy drainage thread cable, it is by aluminum metal flexible pipe, layer of polyester fiber, zinc-plated aluminium strip armour, nickel strap screen, polytetrafluoroethyl-ne propylene insulating barrier, butyronitrile insulating barrier and copper conductor composition, outside described aluminum metal flexible pipe, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up the zinc-plated aluminium strip armour of one deck, outside described zinc-plated aluminium strip armour, wrap up one deck nickel strap screen, outside described nickel strap screen, wrap up one deck polytetrafluoroethyl-ne propylene insulating barrier, described copper conductor is extruded in zinc-plated aluminium strip armour inside.

Between described polytetrafluoroethyl-ne propylene insulating barrier and butyronitrile insulating barrier, be extruded with two aluminum-alloy wire drainage threads.

The utlity model has in sum following beneficial effect: this kind of cable is lightweight, convenient transport, resistance to wear is strong, and anti-tear drawing property is strong, ageing resistance is strong, it is 90 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.
