Abstract
The utility model provides a kind of PVC insulated wires, including core, fibrous layer and protective layer, fibrous layer wraps up core, protective layer wraps up fibrous layer, six stiffeners that protective layer has sheath and is connected with sheath, each stiffener is circumferentially evenly distributed on the outside of sheath, filled PVC resin between adjacent stiffener, and the cross section of protective layer is made to form a regular hexagon.The utility model has many advantages, such as that tensile strength, bend resistance intensity are higher.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, is related to a kind of PVC insulated wires.
Background technology
One layer of non electrically conductive material is hermetically uniformly wrapped up in conducting wire periphery, such as PVC forms insulating layer, prevents conduction
Body contacts the electric wire accidents such as cause electric leakage, short circuit, get an electric shock occur with the external world and is referred to as PVC insulated conductors.
PVC insulated wires are common electrified wires, the insulated wire used under construction or complex environment, typically just
A kind of conducting wire of outsourcing insulation, is arranged fibrous layer between core and insulating layer, for providing tensile strength, since environment is multiple
Miscellaneous, insulated wire is pressurized or bending, be easy to cause local damage, to cause electric leakage unexpected, that is, existing insulated wire bend resistance energy
Power, it is anti-trample, compressive property it is poor, be unfavorable for using under complex environment.
Utility model content
The purpose of this utility model is the existing above problem in view of the prior art, provides a kind of PVC insulated wires, this reality
The technical problem to be solved is that the bend resistances and compressive property that how to improve insulated wire with novel.
The purpose of this utility model can be realized by following technical proposal：A kind of PVC insulated wires, which is characterized in that packet
Core, fibrous layer and protective layer are included, the fibrous layer wraps up core, and the protective layer wraps up fibrous layer, and the protective layer has
Sheath and six stiffeners being connected with sheath, each stiffener are circumferentially evenly distributed on the outside of sheath, adjacent stiffener
Between filled PVC resin, and make protective layer cross section formed a regular hexagon.
In the present solution, by the way that protective layer is arranged, it can be with the bend resistance ability of reinforced insulation line, and can keep certain soft
Softness, six equally distributed structures of stiffener, can cope with the pressure of different directions, make core maintain basic configuration without by
Ectocine.
The insulated wire of regular hexagon can be overlapped neatly in coiling, and insulated wire distorts when to prevent coiling, to
It ensures that the core in insulated wire is not influenced in process of production by bad operation, maloperation etc., and is damaged.
Core has the fabulous performance for preventing pressure from concentrating, uses, pacify under complex environment under the action of protective layer
Quan Xinggao.
In a kind of above-mentioned PVC insulated wires, there is the casing of package core between the fibrous layer and core.
The effect of spool is wrapped to core, and core play is prevented, furthermore, spool is also used for the fixation of limit layer.
In a kind of above-mentioned PVC insulated wires, described sleeve pipe is silastic material.
In a kind of above-mentioned PVC insulated wires, the protective layer is pvc material.
Strength for polyvinyl chloride is moderate, and high temperature resistant, the coefficient of expansion are small.
In a kind of above-mentioned PVC insulated wires, the core is more aluminum steels.
Description of the drawings
Fig. 1 is the sectional view of this PVC insulated wires.
In figure, 1, core；2, fibrous layer；3, protective layer；31, sheath；32, stiffener；4, casing.
Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this insulated wire includes core 1, fibrous layer 2 and protective layer 3, fibrous layer 2 wraps up core 1, protective layer 3
Package fibrous layer 2, six stiffeners 32 that protective layer 3 has sheath 31 and is connected with sheath 31, each stiffener 32 are circumferential uniformly
It is distributed in the outside of sheath 31, filled PVC resin between adjacent stiffener 32, and the cross section of protective layer 3 is made to form one positive six
Side shape.
In the present solution, by the way that protective layer 3 is arranged, it can be with the bend resistance ability of reinforced insulation line, and can keep certain
Pliability, six 32 equally distributed structures of stiffener, can cope with the pressure of different directions, and core 1 is made to maintain basic configuration
Without by ectocine.
The insulated wire of regular hexagon can be overlapped neatly in coiling, and insulated wire distorts when to prevent coiling, to
It ensures that the core 1 in insulated wire is not influenced in process of production by bad operation, maloperation etc., and is damaged.
Core 1 has the fabulous performance for preventing pressure from concentrating, is used under complex environment under the action of protective layer 3,
It is safe.
There is the casing 4 of package core 1 between fibrous layer 2 and core 1；The effect of spool is wrapped to core 1, is prevented
Only 1 play of core, furthermore, spool is also used for the fixation of limit layer.
Casing 4 is silastic material；Protective layer 3 is pvc material；Strength for polyvinyl chloride is moderate, high temperature resistant, expansion
Coefficient is small.
Preferably, core 1 is more aluminum steels.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
