Abstract
The utility model discloses a kind of environment-friendly type special cable, comprise cable core, be coated on lapping layer and the restrictive coating of described cable core outside, described cable core is formed by four soft structure conductor strand, and described soft structure conductor outside is coated with insulating barrier, be filled with asbestos filler in space between described soft structure conductor and lapping layer, between described lapping layer and restrictive coating, be also coated with armour.A kind of environment-friendly type special cable that the utility model discloses, sheath adopts low smoke and zero halogen material, after making cable discarded can recycling or bury, burning can not to environmental danger.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of environment-friendly type special cable.
Background technology
Along with the development of society, and the demand of people to electric power constantly increases, and the demand as the electric wire of electric power transfer main carriers also gets more and more.The most important electric property of electric wire is that realization decay is low, impedance is even, return loss is high, most important mechanical performance is bending property (especially under low temperature), tensile strength, compression strength and anti-wear performance, and electric wire also should be able to bear transport, storage, installation and the environmental stress in using.If electric wire is arranged on the high place of fire safety demands, its fire protecting performance is also very important, and wherein three most important factors are: flame-retarding power, smoke density and halogen gas burst size.
Now mostly adopt pvc material to make insulating barrier and the restrictive coating of cable in the cable, containing noxious substances such as lead, cadmium, mercury in polyvinyl chloride, these materials all create serious pollution to nature, are not suitable for a large amount of production.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of environment-friendly type special cable, and sheath adopts low smoke and zero halogen material, after making cable discarded can recycling or bury, burning can not to environmental danger.
For achieving the above object, the utility model proposes following technical scheme:
A kind of environment-friendly type special cable, comprise cable core, be coated on lapping layer and the restrictive coating of described cable core outside, described cable core is formed by four soft structure conductor strand, and described soft structure conductor outside is coated with insulating barrier, be filled with asbestos filler in space between described soft structure conductor and lapping layer, between described lapping layer and restrictive coating, be also coated with armour.
Described insulating barrier is low smoke and zero halogen insulating barrier.
Described lapping layer is polypropylene fire retardant twining package tape.
Described restrictive coating is low smoke and zero halogen sheath.
Described armour is LWA light wire armoured layer.
Compared with prior art, a kind of environment-friendly type special cable that the utility model discloses, sheath adopts low smoke and zero halogen material, after making cable discarded can recycling or bury, burning can not to environmental danger, the asbestos that simultaneously have employed environment-friendly type are as filler, and due to conductor employing is soft structure conductor, in order to ensure its tensile property, add armour, while not reducing cable flexibility, increase tensile property.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model flexible cable.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical scheme of the utility model embodiment.
As shown in Figure 1, a kind of environment-friendly type special cable that the utility model discloses, comprise cable core, be coated on lapping layer 1 and the restrictive coating 2 of described cable core outside, described cable core forms by four soft structure conductors 3 are stranded, and described soft structure conductor outside is coated with insulating barrier 4, is filled with asbestos filler 5 in the space between described soft structure conductor 3 and lapping layer 1, is also coated with armour 6 between described lapping layer 1 and restrictive coating 2.
Wherein, described insulating barrier is low smoke and zero halogen insulating barrier, and described lapping layer is polypropylene fire retardant twining package tape, and described restrictive coating is low smoke and zero halogen sheath, and described armour is LWA light wire armoured layer.
Technology contents of the present utility model and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on teaching of the present invention and announcement; therefore; the utility model protection range should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
