Abstract
The invention relates to a dual-core power cable which comprises two conductors; each conductor is externally provided with a conductor shielding layer; each conductor shielding layer is externally provided with an insulation layer; each insulation layer is externally provided with a copper band shielding layer; each copper band shielding layer is externally provided with an insulation shielding layer; the insulation shielding layer of each conductor is close to each other; each insulation shielding layer is externally provided with a filling layer; each filling layer is externally provided with a tapped covering layer; and each tapped covering layer is externally provided with an outer restrictive coating. The dual-core power cable provided by the invention is reasonable in structure arrangement, has good shielding and flame retardant effect, is high in strength, and is 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 twin-core in order to overcome deficiency of the prior art, and structure arrangement is reasonable, the shielding good flame retardation effect, and intensity is high, is suitable for the twin-core power cable that long distance is set up.
Technical scheme: in order to solve the problems of the technologies described above, a kind of twin-core power cable of the present invention, it comprises two conductors, outside every conductor, be provided with conductor shield, outside described conductor shield, be provided with insulating barrier, outside described insulating barrier, be provided with the copper strip shielding layer, outside described copper strip shielding layer, be provided with insulation screen, the insulation screen of every conductor abuts against together, outside described insulation screen, be provided with packed layer, outside described packed layer, be provided with lapping layer, outside described lapping layer, be provided with external sheath layer.
Described conductor is copper conductor or aluminium conductor.
Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.
Described lapping layer is the nonwoven fabrics 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, external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, has improved the overall flame effect of product.
