Abstract
The invention relates to a three-core power cable which comprises three conductors. A conductor shielding layer is arranged outside each conductor, insulating layers are arranged outside the conductor shielding layers, insulation shielding layers are arranged outside the insulating layers, copper strip shielding layers are arranged outside the insulation shielding layers, the copper strip shielding layers of the three conductors are arranged in adjoining mode, a packing layer is arranged outside the copper strip shielding layers, a wrapping layer is arranged outside the packing layer, an inner sheath layer is arranged outside the wrapping layer, a steel wire armoring layer is arranged outside the inner sheath layer, and an outer sheath layer is arranged outside the steel wire armoring layer. The three-core power cable is good in shielding effect and flame-retarding effect, high in strength and suitable for long-distance erection.
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.
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 some multicore cables, 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 three cores in order to overcome deficiency of the prior art, and shield effectiveness is good, good flame retardation effect, and intensity is high, is suitable for three core power cables that long distance is set up.
Technical scheme: in order to solve the problems of the technologies described above, a kind of three core power cables of the present invention, it comprises three conductors, outside every conductor, all 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, the copper strip shielding layer of three conductors is near setting, outside described copper strip shielding layer, be provided with packed layer, outside described packed layer, be provided with lapping layer, outside described lapping layer, be provided with inner restrictive coating, outside described inner restrictive coating, be provided with the wire armoring layer, outside described wire armoring layer, be provided with external sheath layer.
Described conductor is copper conductor or aluminium conductor or tinned copper conductor.
Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.
Described lapping layer is the polyester belt lapping layer.
Described external sheath layer is pvc sheath layer or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: hierarchical structure arrangement of the present invention is reasonable, adopt multilayer screen, improved shield effectiveness, packed layer adopts composite material to fill layer, can the Effective Raise filling effect, adopt the wire armoring layer, greatly improved bulk strength, external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, has improved flame retardant effect.
