Abstract

The utility model discloses an aluminum-alloy-conductor-wire-core armor sheath flexible cable which includes seven aluminum-alloy conductor wire cores, a zinc-coated copper-strap armor layer, a polyvinyl chloride insulating layer, a tin-plated nickel-strap armor layer, a nickel-strap shielding layer and a low-smoke halogen-free polyolefin sheath layer. The seven aluminum-alloy conductor wire cores are wrapped with a layer of zinc-coated copper-strap armor layer at the outside. The zinc-coated copper-strap armor layer is wrapped with a layer of polyvinyl chloride insulating layer at the outside. The polyvinyl chloride insulating layer is wrapped with a layer of tin-plated nickel-strap armor layer at the outside. The tin-plated nickel-strap armor layer is wrapped with a layer of nickel-strap shielding layer at the outside. 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 aluminium alloy conductor core armouring sheath soft cable

Technical field

The utility model belongs to field of cables, relates 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 fields such as computer, machine room, to the high and low temperature resistance of 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 transportation, the aluminium alloy conductor core armouring sheath soft 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 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 form, 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 utlity model has in sum following beneficial effect: this kind of cable is lightweight, convenient transportation, resistance to wear is strong, cold-resistant high temperature resistant, non-oxidizability is strong, and pull resistance is strong, it is 95 ℃ that this cable allows operational environment maximum temperature, the permission bending radius of this cable is the outside diameter of cable 12 times.
