Abstract

The utility model relates to a polyvinyl chloride insulation power cable. The power cable comprises conductor(s). Each conductor is externally provided with an insulation layer. The insulation layer(s) is (are) externally provided with a filling layer. The filling layer is externally provided with a wrapping belt layer. The wrapping belt layer is externally provided with an outer sheath layer. The thickness of the insulation layer is between 0.8 mm and 2.4 mm; the thickness of the outer sheath layer is between 1.8 mm and 2.7 mm; and the diameter of each conductor is between 1.38 mm and 20.5 mm. The polyvinyl chloride insulation power cable is compact in structure, long in service life, high in overall strength, and uneasy to damage.

Description

A kind of PVC insulated power cable

Technical field

The utility model relates to a kind of cable, is specifically related to a kind of power 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.

At present, the cable on market is various, and they are applied in various different occasions.But all there are some problems in most of cable, such as layer of structure arranges unreasonable, compact not between layers, conductor shape is more single, and packed layer is solid not firmly, and filling effect is not good, the insulating barrier insulation effect is undesirable, and restrictive coating is fragile, and whole service life is shorter.

Summary of the invention

Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of compact conformation is provided, long service life, and bulk strength is high, non-damageable PVC insulated power cable.

Technical scheme: in order to solve the problems of the technologies described above, a kind of PVC insulated power cable described in the utility model, it comprises conductor, be provided with insulating barrier in described conductor outside, in described insulating barrier outside, be provided with packed layer, in described packed layer outside, be provided with belting layer, be provided with external sheath layer in described belting layer outside, the thickness of described insulating barrier is between 0.8-2.4mm, and the thickness of described external sheath layer is between 1.8-2.7mm, and the diameter of described conductor is between 1.38-20.5mm.

Described conductor is for pressing circular stranded conductor or pressing sector conductor, and is at least one.

Described conductor is copper conductor or aluminium conductor.

Described insulating barrier is the polyvinyl chloride insulation layer.

Described packed layer is the composite material of silicon carbide packed layer.

Described belting layer is the polyester belt lapping layer.

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

When conductor described in the utility model is one, do not need to use packed layer.

Conductor described in the utility model can all use and press circular stranded conductor, also can all use and press sector conductor, can also press circular stranded conductor and press sector conductor to be used in conjunction with, and is used for meeting different instructions for uses.

beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model compact overall structure, be connected between each layer, reliable, adopt the insulating barrier between 0.8-2.4mm, can effectively guarantee insulation effect, adopt the external sheath layer between 1.8-2.7mm, can guarantee that the cable outside is more solid firmly, not fragile, adopt the composite material of silicon carbide packed layer, can effectively improve filling effect, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can improve the cable result of use, integral product is longer useful life, realistic instructions for use.
