Abstract

The utility model relates to a novel steel-cored aluminum strand wire cable, which comprises a steel-cored layer; an aluminum conductor layer is arranged outside the steel-cored layer; an insulating layer is arranged outside each aluminum conductor; a filling layer is arranged outside the insulating layer; an inner sheath layer is arranged outside the fill layer; a steel wire armor layer is arranged outside the inner sheath layer; a wrapping layer is arranged outside the steel wire armor layer; and an outer sheath layer is arranged outside the wrapping layer. The novel steel-cored aluminum strand wire cable provided by the utility model has multiple functions and good effects in use, and is good in flame resistance and high in strength.

Description

A kind of Novel steel core aluminum stranded wire cable

Technical field

The utility model relates to a kind of cable, is specifically related to a kind of steel reinforced aluminium conductor cable.

Background technology

Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.

The common cable of existing market can not satisfy instructions for use at some special occasions, and structure is more single, and function is also fewer.And unreasonable owing to arranging between the conductor in the multicore cable, can exert an influence each other, the shielding texts is bad, and the packed layer materials in the multicore cable are general, result of use is undesirable.

Summary of the invention

Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of multi-functional, and result of use is good, and is fire-retardant good, the Novel steel core aluminum stranded wire cable that intensity is high.

Technical scheme: in order to solve the problems of the technologies described above, a kind of Novel steel core aluminum stranded wire cable described in the utility model, it comprises the steel core layer, outside described steel core layer, be provided with the aluminium conductor layer, outside every aluminium conductor, be provided with insulating barrier, outside described insulating barrier, be provided with packed layer, outside described packed layer, be provided with inner restrictive coating, outside described inner restrictive coating, be provided with the wire armoring layer, outside described wire armoring layer, be provided with lapping layer, outside described lapping layer, be provided with external sheath layer.

Described steel core layer is comprised of steel wire.

Described insulating barrier is black crosslinkable polyethylene layer or weatherability black PVC layer.

Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.

Described inner restrictive coating is the pvc sheath layer.

Described lapping layer is the polyester belt lapping layer.

Described external sheath layer is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.

Beneficial effect: the utility model compared with prior art, its remarkable advantage is: insulating barrier of the present utility model adopts weatherability black PVC layer, improved insulation effect, packed layer adopts the composite material of silicon carbide packed layer, has greatly improved filling effect, adopts armour, greatly improved the intensity of product, external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, has improved the flame retardant effect of product, and whole usage comparison is desirable.
