Abstract

The utility model relates to a fire-resistant power cable. The fire-resistant power cable comprises a conductor, wherein a fire-resistant layer is arranged outside the conductor, an insulating layer is arranged outside the fire-resistant layer, a filling layer is arranged outside the insulating layer, a belting layer is arranged outside the filling layer, and an outer sheath layer is arranged outside the belting layer; and the thickness of the insulating layer ranges from 0.5 to 2 mm, and the thickness of the outer sheath layer ranges from 0.8 to 1.2 mm. The fire-resistant power cable disclosed by the utility model is long in service life, fire-resistant, high in overall strength, and capable of ensuring normal working.

Description

A kind of fireproof 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 the market is various, and they are applied in various different occasions.But all there are some problems in most of cable, such as when the breaking out of fire, and the easy heat damage of cable, thus affect the overall operation of cable, can not long-time continual work 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 is fire-resistant, and bulk strength is high, can guarantee the fireproof power cable of normal operation.

Technical scheme: in order to solve the problems of the technologies described above, a kind of fireproof power cable described in the utility model, it comprises conductor, be provided with flame retardant coating in described conductor outside, be provided with insulating barrier in described flame retardant coating outside, be provided with packed layer in described insulating barrier outside, be provided with belting layer in described packed layer outside, be provided with external sheath layer in described belting layer outside, the thickness of described insulating barrier is between 0.5-2mm, and the thickness of described external sheath layer is between 0.8-1.2mm.

Described conductor is copper core conductor or aluminium core conductor, totally two.

Described insulating barrier and external sheath layer are polyvinyl chloride layer.

Described flame retardant coating is inorganic short fiber adhesive-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 0.5-2mm, play good insulating effect; adopt the external sheath layer between the 0.8-1.2mm; play a very good protection, so that integral body is not fragile, improved whole service life; adopt inorganic short fiber adhesive-layer as flame retardant coating; have good fire-resistant effect, when fiery residence occurs, the normal operation that can keep cable; adopt the composite material of silicon carbide packed layer; play good filling effect, strengthened the intensity of product, the realistic instructions for use of this product.
