Fig. 2 is a schematic view of the utility model of still spirally winding or cladding between the outside of the cable body and the insulating sheath with a layer of flame retardant material (when peeling off the insulating sheath and the ultraviolet-proof coating condensation layer, or when not coating the insulating coating and the ultraviolet-proof coating).
Fig. 3 is a schematic view of the insulating sheath of the present invention.
Wherein: 1. the cable comprises a cable main body 2, an insulating protective layer 3, an ultraviolet-proof paint condensation layer 4, a flame retardant material layer 5 and an insulating sleeve.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, a cable coated with an insulating layer comprises a conductive cable body 1 and a sheath outside the cable body; the method is characterized in that: the coating is a coating in which an insulating coating is sprayed and condensed, and this coating is the insulating coating 2.
The utility model discloses because the insulating sheath of cable body outside is insulating coating spraying and condenses and form, have production simple process, reduction in production cost's advantage.
The insulating paint is the insulating paint in the prior art.
Particularly, for the cable installed on the wire pole, there is no way to form the insulating sheath by thermal cladding, because the cable is on the wire pole, and the cable with the insulating sheath can be formed by adopting a spraying method, so that the purpose of the utility model is realized.
Preferably, the thickness of the insulating sheath is 1 to 3 mm.
Furthermore, the outer surface of the insulating protective layer is also provided with an ultraviolet-proof paint condensation layer 3 formed by spraying and condensation.
The utility model discloses set up like this, the cable of formation still has better anti ultraviolet's advantage.
Preferably, the thickness of the ultraviolet-proof paint condensation layer is 1-2 mm.
Furthermore, a flame retardant material layer 4 is spirally wound or coated between the outside of the cable body and the insulating sheath.
The utility model discloses set up like this, the cable of formation still has better flame retardant efficiency.
The coating can be formed by, for example, cutting the side surface of a cylindrical flame retardant material to form a structure with a C-shaped section and clamping the cable body.
Furthermore, the insulating protective layer or/and the ultraviolet-proof paint condensation layer also has a structure that one side is thick and the other layer is thin.
As shown in fig. 1, the cable has a thick insulating sheath and/or ultraviolet-screening paint condensation layer on the upper left side and a thin insulating sheath and/or ultraviolet-screening paint condensation layer on the lower right side.
Further, as shown in fig. 3, an insulating sleeve 5 is clamped outside the ultraviolet-proof paint condensation layer, and the section of the insulating sleeve is in a C-shaped structure.
On one hand, one side (the side facing the sun) of the cable body requires that the insulating protective layer or/and the ultraviolet-proof paint condensation layer is thin, so that the insulating protective layer or/and the ultraviolet-proof paint condensation layer on the side has a better insulating effect and a stronger ultraviolet-proof function, and the insulating protective layer or/and the ultraviolet-proof paint condensation layer on the side can be designed to be thicker; on the other hand, the insulating sheath and the ultraviolet blocking paint condensation layer formed by spraying also cause unevenness around the cable, and for example, a thicker structure of the insulating sheath and the ultraviolet blocking paint condensation layer is more likely to be formed at a portion facing the head.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art can make some changes or modifications to equivalent embodiments by utilizing the above-mentioned technical contents without departing from the technical scope of the present invention, but all those persons do not depart from the technical scope of the present invention.
