Abstract
The invention relates to a fireproof power cable which comprises a conductor. A fireproof layer is arranged outside the conductor, an insulating layer is arranged outside the fireproof layer, a filling layer is arranged outside the insulating layer, a wrapping tape layer is arranged outside the filling layer, an outer sheath layer is arranged outside the wrapping tape layer, the thickness of the insulating layer is between 0.5mm and 2mm, and the thickness of the outer sheath layer is between 0.8mm and 1.2mm. The fireproof power cable is long in service life, good in fire resistance, high in whole strength and capable of guaranteeing normal work.
Description
Technical field
The present invention relates to a kind of cable, be 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 when the breaking out of fire, 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 object of the invention is, in order to overcome deficiency of the prior art, provides a kind of long service life, and fire-resistant, bulk strength is high, can guarantee normal fireproof power cable of working.
Technical scheme: in order to solve the problems of the technologies described above, a kind of fireproof power cable of the present invention, it comprises conductor, in described conductor outside, be provided with flame retardant coating, in described flame retardant coating outside, be provided with insulating barrier, in described insulating barrier outside, be provided with packed layer, in described packed layer outside, be provided with belting layer, in described belting layer outside, be provided with external sheath layer, 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 composite material of silicon carbide packed layer.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: compact overall structure of the present invention, between each layer, be connected, reliable, adopt the insulating barrier between 0.5-2mm, play good insulating effect, adopt the external sheath layer between 0.8-1.2mm, play a very good protection, make integral body not fragile, improved whole service life, adopt inorganic short fiber adhesive-layer as flame retardant coating, there is good fire-resistant effect, when fiery residence occurs, the normal work that can keep cable, adopt composite material of silicon carbide packed layer, play good filling effect, strengthened the intensity of product, the realistic instructions for use of this product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein:
1, conductor; 2, flame retardant coating; 3, insulating barrier; 4, packed layer; 5, belting layer; 6, external sheath layer
