Abstract
The invention 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 packing layer is arranged outside the insulating layer, an inner sheath layer is arranged outside the packing layer, an armor layer is arranged outside the inner sheath layer, an outer sheath layer is arranged outside the armor layer, the thickness of the insulating layer is 1-1.2 mm, the thickness of the inner sheath layer is 0.6-1 mm, and the thickness of the outer sheath layer is 1.8-2.1 mm. The cross linked polyethylene insulated power cable is long in service life, good in insulation effect and high in overall strength.
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 most of cable all exists some problems, such as insulation effect is bad, bulk strength is poor, and useful life is short 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 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 of the present invention, 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 crosslinked polyethylene layer.
Described inner restrictive coating and external sheath layer are polyvinyl chloride layer.
Described armour is LWA light wire armoured 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 1-1.2mm, play good insulation effect, inner restrictive coating between employing 0.6-1mm and the external sheath layer between 1.8-2.1mm, make all to be protected inside and outside product, improve product useful life, adopt LWA light wire armoured layer, can play the bulk strength of product, in use, there is good toughness, adopt composite material of silicon carbide packed layer, can play good filling effect, improve the intensity of product simultaneously, the realistic instructions for use of this product.
