Abstract
The utility model discloses a high fire -retardant polyvinyl chloride insulated wire, the interior protective layer, external insulation layer and the fire -retardant external coating that set gradually including from interior to exterior each group's copper strands outside parcel is equipped with multiunit copper strands in the interior protective layer and having the inner insulating layer, fire -retardant external coating is made by the polyvinyl chloride material. The utility model discloses a high fire -retardant polyvinyl chloride insulated wire simple structure is and fire behaviour is good.
Description
Technical field
This utility model relates to a kind of cable and wire, particularly to a kind of high flame retardant polyvinyl chloride insulated cable electric wire.
Background technology
At present, traditional cable electric wire pattern is more, multifarious, but, traditional cable fire resistance is comparatively general.How to solve above-mentioned technical barrier, become the technical barrier needing to be captured.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of high flame retardant polyvinyl chloride insulated electric conductor, and this high flame retardant polyvinyl chloride insulated electric conductor simple in construction and fire resistance are good.
For solving the problems referred to above, this utility model adopts the technical scheme that
A kind of high flame retardant polyvinyl chloride insulated electric conductor, including the inner protective layer set gradually from the inside to the outside, external insulation layer and fire-retardant external protection, is provided with outside many group copper stranded conductors and each group of copper stranded conductor in described inner protective layer and is enclosed with inner insulating layer；Described fire-retardant external protection is made up of pvc material.
Gap between described many group copper stranded conductors be provided with filling plastic layer and respectively group copper stranded conductor form the many groups of structures that are circular layout.
One layer of fire-retardant copper stranded conductor protective layer being made up of pvc material also it is enclosed with outside each inner insulating layer.
After adopting said structure, this utility model achieves following beneficial effect:
This utility model inner protective layer, external insulation layer and fire-retardant external protection by setting gradually from the inside to the outside, is provided with outside many group copper stranded conductors and each group of copper stranded conductor in described inner protective layer and is enclosed with inner insulating layer；Described fire-retardant external protection is made up of pvc material, and pvc material has high flame resistance.High flame retardant polyvinyl chloride insulated electric conductor simple in construction of the present utility model and fire resistance are good.
After the detailed description reading in conjunction with the accompanying embodiment of the present utility model, feature of the present utility model and advantage will become clearer from.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In one embodiment this utility model being described in further detail below, but it should illustrate, protection domain of the present utility model is not limited only to this.
Consult Fig. 1; a kind of high flame retardant polyvinyl chloride insulated electric conductor; including the inner protective layer 3 set gradually from the inside to the outside, external insulation layer 2 and fire-retardant external protection 1, it is provided with outside many group copper stranded conductors 5 and each group of copper stranded conductor 5 in described inner protective layer 3 and is enclosed with inner insulating layer 4；Described fire-retardant external protection 1 is made up of pvc material.
Gap between described many group copper stranded conductors 5 be provided with filling plastic layer 7 and respectively group copper stranded conductor 5 form the many groups of structures that are circular layout, make structure between copper stranded conductor 5 compacter and more make full use of the space in inner protective layer 3.
Outside each inner insulating layer 4, also it is enclosed with one layer of fire-retardant copper stranded conductor protective layer 6 being made up of pvc material, also further increases fire resistance of the present utility model.
Although being described in conjunction with the accompanying embodiment of the present utility model; but those skilled in the art can make various deformation or amendment within the scope of the appended claims; as long as less than the protection domain described by claim of the present utility model, all should within protection domain of the present utility model.
