Abstract
The invention relates to a multicore combined power cable. The multicore combined power cable comprises a conductor, wherein a conductor shielding layer is arranged outside the conductor, an insulating layer is arranged outside the conductor shielding layer, an insulating and shielding layer is arranged outside the insulating layer, a copper belt shielding layer is arranged outside the insulating and shielding layer, a packing layer is arranged outside the copper belt shielding layer, a non-woven layer is arranged outside the packing layer, an inner sheath layer is arranged outside the non-woven layer, a steel tape armored layer is arranged outside the inner sheath layer, and an outer sheath layer is arranged outside the steel tape armored layer. The multicore combined power cable has the flame retardant effect, and simultaneously is higher in product strength and good in shielding and insulating effects.
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 develop rapidly of China's modernization construction, 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.Power cable refers to each or a plurality of conductor outer wrap one deck annular insulating barrier, and conductor and insulating barrier share the electric wire in same axle center, and then whole cable is encased by the sheath of polyvinyl chloride or other materials, carries out the conduction instrument of electric energy transmitting.
The single-core power cables of existing market can not satisfy instructions for use at some special occasions, and structure is more single, and function is also fewer.And unreasonable owing to arranging between the conductor in the multicore cable, can exert an influence each other, the shielding texts is bad, and the packed layer materials in the multicore cable are general, result of use is undesirable.In addition, the bulk strength of cable is inadequate, when built on stilts the use, can not grow distance and set up.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of flame retardant effect that has in order to overcome deficiency of the prior art, and product strength is higher simultaneously, the multicore combination of power cable that shielding insulation is effective.
Technical scheme: in order to solve the problems of the technologies described above, a kind of multicore combination of power cable of the present invention, it comprises conductor, outside described conductor, be provided with conductor shield, outside described conductor shield, be provided with insulating barrier, outside described insulating barrier, be provided with insulation screen, outside described insulation screen, be provided with the copper strip shielding layer, outside described copper strip shielding layer, be provided with packed layer, at described packed layer peripheral hardware nonwoven layer is arranged, outside described nonwoven layer, be provided with inner restrictive coating, outside described inner restrictive coating, be provided with the steel-tape armouring layer, outside described steel-tape armouring layer, be provided with external sheath layer.
Described conductor is copper conductor or tinned copper conductor.
Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.
Described external sheath layer is flexible polyvinyl chloride restrictive coating or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
The thickness of described steel-tape armouring layer is 0.5-1mm.
Described conductor is at least two.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: structure arrangement of the present invention is reasonable, can not interact between the conductor and affect the cable result of use, adopt multilayer screen, improved shield effectiveness, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer to improve the flame retardant effect of product, and packed layer and armour have strengthened the intensity of product.
