Abstract
The utility model relates to a color-separating cable core with double insulation layers, comprising a conductor and an insulation layer extruded and coated outside the conductor. The utility model is characterized in that the insulation layer is composed of two layers of insulation materials, namely, an inner insulation layer and an outer bepainting insulation layer. The inner layer of the insulation cable core structure of the utility model adopts natural-color insulation material, while the outer layer adopts bepainting insulation material; therefore, the paint using amount can be obviously reduced in the production process so as to effectively reduce the production cost of the cables.
Description
Technical field
The utility model relates to a kind of color separation cable core that has double insulating layer.
Background technology
Regulation according to GB6995.4～GB6995.5 (electric wire distinguishing mark): electrical equipment wire cable insulating core, the following cable of five cores generally should adopt color identification, and the insulation of cable core should be adopted painted Insulation Material or adopt other suitable method painted on the surface of insulation; Crosslinked polyetylene insulated or polyethylene insulation or polyvinyl chloride insulation power cable, insulated wire cores should adopt color identification, and polyvinyl chloride cable generally should adopt painted Insulation Material, and the insulated wire cores of easy coloring allows to adopt sign yarn or tracer stripe.
Polyvinyl chloride cable, the general employing of insulated wire cores extrudes the painted Insulation Material of one deck, and this color separation cable is wasted pigment in process of production.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can significantly reduce the pigment use amount, effectively reduces the cable production cost and the double insulating layer color separation cable core that has dyed layer that be easy to discern.
The utility model adopts following technical scheme:
The utility model comprises conductor and is extruded in the outer insulating barrier formation of conductor, it is characterized in that described insulating barrier is made of inner insulating layer and extrinsic color insulating barrier two layers of insulation material.
The utility model good effect is as follows: the utility model insulated wire cores structure internal layer adopts true qualities Insulation Material, the painted Insulation Material of outer employing, clearly can significantly reduce the use amount of pigment in process of production, can effectively reduce the cable production cost.
The utility model is applicable to following cable insulation core:
1, rated voltage 1.8/3kV and following plastic insulation power cable;
2, electrical equipment electric wire;
3, rated voltage 450/750V plastic insulation control cable.
Description of drawings
Accompanying drawing 1,2 adopts fan-shaped and round cable structural representation for the utility model
Accompanying drawing 3,4 adopts fan-shaped and round cable user mode figure for the utility model
In the accompanying drawings: 1 conductor, 2 inner insulating layers, 3 painted insulating barriers, 4 gasket for packings, the tight band of 5 strandings, 6 inner sheaths, 7 steel-tape armourings, 8 oversheaths, 9 fillers
Embodiment
Shown in accompanying drawing 1,2, the utility model comprises conductor 1 and is extruded in conductor 1 insulating barrier formation outward, it is characterized in that described insulating barrier is made of inner insulating layer 2 and extrinsic color insulating barrier 3 two layers of insulation material.
Cable adopts 4 the utility model sector cable cores as shown in Figure 3, is respectively arranged with gasket for packing 4, the tight band 5 of stranding, inner sheath 6, steel-tape armouring 7, oversheath 8 and makes finished cable outside the utility model cable core.
Cable adopts 4 the utility model round cable cores as shown in Figure 4, is respectively arranged with the tight band 5 of stranding, inner sheath 6, steel-tape armouring 7, oversheath 8, filler 9 and makes finished cable outside the utility model cable core.
The utility model insulated wire cores structure is that internal layer adopts true qualities Insulation Material, the painted Insulation Material of outer employing, clearly can significantly reduce the use amount of pigment in process of production, effectively reduces the cable production cost.
