Abstract

The utility model relates to a cross-linked polyethylene insulated power cable. The cross-linked polyethylene insulated power cable comprises a conductor, wherein an insulating layer is arranged outside the conductor, a filling layer is arranged outside the insulating layer, an inner sheath layer is arranged outside the filling layer, an armouring layer is arranged outside the inner sheath layer, and an outer sheath layer is arranged outside the armouring layer; and the thickness of the insulating layer ranges from 1 to 1.2 mm, the thickness of the inner sheath layer ranges from 0.6 to 1 mm, and the thickness of the outer sheath layer ranges from 1.8 to 2.1 mm. The cross-linked polyethylene insulated power cable disclosed by the utility model is long in service life, good in insulating effect, and high in overall strength.

Description

A kind of power cable with cross-linked polyethylene insulation

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 the market is various, and they are applied in various different occasions.But all there are some problems in most of cable, and is bad such as insulation effect, and bulk strength is relatively poor, and useful life is short etc.

Summary of the invention

Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, a kind of long service life to be provided, and insulation effect is good, the power cable with cross-linked polyethylene insulation that bulk strength is high.

Technical scheme: in order to solve the problems of the technologies described above, a kind of power cable with cross-linked polyethylene insulation described in the utility model, it comprises conductor, be provided with insulating barrier in described conductor outside, be provided with packed layer in described insulating barrier outside, be provided with inner restrictive coating in described packed layer outside, be provided with armour in described inner restrictive coating outside, be provided with external sheath layer in described armour outside, the thickness of described insulating barrier is between 1-1.2mm, the thickness of described inner restrictive coating is between 0.6-1mm, and the thickness of described external sheath layer is between 1.8-2.1mm.

Described conductor is copper core conductor or aluminium core conductor.

Described conductor is sector conductor, totally two.

Described insulating barrier is the crosslinked polyethylene layer.

Described inner restrictive coating and external sheath layer are polyvinyl chloride layer.

Described armour is the LWA light wire armoured layer.

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

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 the 1-1.2mm, play good insulation effect, the inner restrictive coating between the employing 0.6-1mm and the external sheath layer between the 1.8-2.1mm; so that all be protected inside and outside the product; improve product useful life, adopt the LWA light wire armoured layer, can play the bulk strength of product; in use; have good toughness, adopt the composite material of silicon carbide packed layer, can play good filling effect; improve simultaneously the intensity of product, the realistic instructions for use of this product.
