The interlocking armored aluminum alloy cable has the advantages of low cost, light weight, good electrical conductivity, good connection performance, corrosion prevention, creepage resistance, security and environmental protection.

Description

A kind of lock armo aluminium alloy cable

Technical field

The utility model relates to a kind of cable, particularly a kind of lock armo aluminium alloy cable.

Background technology

Along with the development of power industry, people are also more and more for the demand of cable, and traditional cable adopts copper core and aluminium core mostly.Deficiency of the prior art is that the cost of copper core uprises because the present situation of the rich aluminium of current poor copper is more and more serious, and economic benefit reduces; Although aluminium cable price is low, its bad mechanical property, connect unstable, the bad same economic benefit that affects of security performance.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, and a kind of lock armo aluminium alloy cable is provided, and it adopts aluminium alloy to replace copper core and aluminium core, has improved mechanical performance, the security performance of cable, has promoted economic benefit.

In order to reach above object, the technical solution adopted in the utility model is: a kind of lock armo aluminium alloy cable, and it includes conductor (1), packed layer (6), twining package tape (7), inner covering (8), lock armo layer (9); It is characterized in that, described conductor (1) forms by aluminum-alloy wire is stranded, and the outside of conductor (1) is from inside to outside provided with conductor shield (2), insulating barrier (3), insulation screen (4), metal screen layer (5) successively; Described packed layer (6) is wrapped in metal screen layer (5) outside; Described twining package tape (7) is coated on packed layer (6) outside; Described inner covering (8) is coated on twining package tape (7) outside; Described lock armo layer (9) is coated on inner covering (8) outside.

Under better enforcement state, described insulating barrier (3) is made by cross-linking polyethylene materials.

Under better enforcement state, described lock armo layer (9) is made by aluminum alloy strip.

The beneficial effects of the utility model be to provide a kind of cost low, lightweight, conduct electricity very well, switching performance is good, the lock armo aluminium alloy cable of anticorrosion, creep resistant, safety and environmental protection.
