Abstract
The utility model proposes smeared on the outside of a kind of novel high-pressure coiling film envelope curve, including the nonwoven polyester fabric layer of conductor layer, the laminated polyester film of conductor layer outer side covers, the film layer of laminated polyester film outer side covers, film layer outer side covers, nonwoven polyester fabric layer from haircuts layer；Described conductor layer outer surface is provided with some grooves being equally spaced.A kind of novel high-pressure coiling film envelope curve of the present utility model, be followed successively by from inside to outside conductor layer, laminated polyester film, film layer, nonwoven polyester fabric layer, from haircuts layer, film layer has good wear-resisting and resistance to cracking energy, stable chemical performance, it can improve the life-span of film envelope curve, outermost layer is provided with from haircuts, and the adhesive strength between adjacent wires can be improved after heated thawing, prevent wire from shifting, improve the life-span of film envelope curve.
Description
Technical field
It the utility model is related to a kind of film envelope curve, and in particular to a kind of novel high-pressure coiling film envelope curve.
Background technology
Outdoor use high voltage winding group is made using film envelope curve at present, i.e., outside exposed aluminum conductor, coats polyester film successively,
Nonwoven polyester fabric, the good insulating performance and high-melting-point of polyester film can ensure the insulating properties and heat resistance of film envelope curve
Can, and the nonwoven polyester fabric for being coated on outer layer has the ability that very strong extension covers resin glue so that film envelope curve is for twining
During around making winding, hang the resin glue covered and nonwoven polyester fabric layer bonding is firm.But existing film envelope curve by
During extruding, it is impossible to keep original shape well, be unfavorable for long-term use.
Utility model content
In order to solve the above problems, the utility model proposes a kind of novel high-pressure coiling film envelope curve.
The technical solution of the utility model is：Covered on the outside of a kind of novel high-pressure coiling film envelope curve, including conductor layer, conductor layer
The laminated polyester film of lid, the film layer of laminated polyester film outer side covers, the polyester of film layer outer side covers are fine
Tie up nonwoven fabric layer, smear on the outside of nonwoven polyester fabric layer from haircuts layer；Described conductor layer outer surface is provided with some etc.
Groove away from distribution.
Further, described conductor layer is circular aluminum wire.
Further, described laminated polyester film is Kapton.
Further, the thickness from haircuts layer is 0.1 millimeter.
Further, the depth of described groove is 0.05 millimeter.
Beneficial effect
A kind of novel high-pressure coiling film envelope curve of the present utility model, conductor layer, laminated polyester film are followed successively by from inside to outside, is gathered
Vinyl film layer, nonwoven polyester fabric layer, from haircuts layer, film layer has good wear-resisting and resistance to cracking energy,
Stable chemical performance, it is possible to increase the life-span of film envelope curve, outermost layer are provided with from haircuts, and adjacent lead can be improved after heated thawing
Adhesive strength between line, prevents wire from shifting, and improves the life-span of film envelope curve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1- conductor layers, 2- laminated polyester films, 3- film layers, 4- nonwoven polyester fabrics layer, 5- are from haircuts
Layer.
Embodiment
A kind of novel high-pressure coiling film envelope curve of the present utility model is elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of novel high-pressure coiling film envelope curve, including conductor layer 1, the polyester of the outer side covers of conductor layer 1
Film layer 2, the film layer 3 of the outer side covers of laminated polyester film 2, the polyester fiber of the outer side covers of film layer 3 is non-knits
Layer of cloth 4, the outside of nonwoven polyester fabric layer 4 smear from haircuts layer 5；The described outer surface of conductor layer 1 is provided with some equidistant
The groove of distribution；Described conductor layer 1 is circular aluminum wire；Described laminated polyester film 2 is Kapton；Described
It it is 0.1 millimeter from the thickness of haircuts layer 5；The depth of described groove is 0.05 millimeter.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, although the utility model is disclosed above with preferred embodiment, but be not limited to the utility model, it is any ripe
Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, any simple modification, equivalent change and modification made according to the technical essence of the utility model to above example, still
Belong to the scope of technical solutions of the utility model.
