Abstract

The invention discloses an armoured sheath flexible cable with aluminum alloy conductor cable cores. The cable consists of the aluminum alloy cable cores, a galvanized copper strap armoured layer, a polyvinyl chloride insulated layer, a tinned nickel strap armoured layer, a nickel strap shield layer and a low-smoke halogen-free polyolefin sheath layer. Seven groups of aluminum alloy conductor cable cores are arranged, and are wrapped by the galvanized copper strap armoured layer which is wrapped by the polyvinyl chloride insulated layer, the polyvinyl chloride insulated layer is wrapped by the tinned nickel strap armoured layer which is wrapped by the nickel strap shielding layer. The cable is low in weight, convenient to convey, strong in wear-resistance, cold-resistant and high-temperature resistant, strong in inoxidizability, and strong in tensile stress, the allowable highest temperature of the working environment of the cable is 95 DEG C, and the allowable bending radius of the cable is 12 times of the outer diameter of the cable.

Description

A kind of aluminium alloy conductor core armouring sheath soft cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of aluminium alloy conductor core armouring sheath soft 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.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of pull resistance strong, convenient transport, the aluminium alloy conductor core armouring sheath soft cable cold-resistant high temperature resistant, non-oxidizability is strong.

The present invention takes following technical scheme to realize: a kind of aluminium alloy conductor core armouring sheath soft cable, it is by aluminium alloy conductor core, zinc-plated copper strips armour, polyvinyl chloride insulation layer, zinc-plated nickel strap armour, nickel strap screen and low-smoke halogen-free polyolefin restrictive coating composition, described aluminium alloy conductor core has seven groups, outside seven group aluminum alloy conductor thread cores, wrap up the zinc-plated copper strips armour of one deck, outside described zinc-plated copper strips armour, wrap up one deck polyvinyl chloride insulation layer, outside described polyvinyl chloride insulation layer, wrap up the zinc-plated nickel strap armour of one deck, outside described zinc-plated nickel strap armour, wrap up one deck nickel strap screen.

Described aluminium alloy conductor core inside is extruded with an aluminum metal flexible pipe.

The present invention has following beneficial effect in sum: this kind of cable is lightweight, convenient transport, and 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.
