Abstract
The utility model discloses a kind of new PVC power cords, including conductor, the first PVC sets, the 2nd PVC sets and inner sheath, the outer surface of the conductor is coated with insulating layer, the outer surface of insulating layer is coated with inner sheath, inner sheath is located at the inside of the first PVC sets, the inner wall fixed bonding of first PVC sets has the 2nd PVC sets, and glass fibre is filled in the 2nd PVC sets；Due to being provided with the first PVC sets and the 2nd PVC sets; multiple-protection; when the first PVC covers breakage; internal inner sheath is protected by the 2nd PVC sets; it avoids due to the situation that power cord makes external PVC sets damaged for a long time and conductor is caused to leak out; and filled with glass fibre in the 2nd PVC sets, therefore increase its insulation performance, heat resistance, corrosion resistance and mechanical strength, improve the security performance and service life of power supply.
Description
Technical field
The utility model is related to power cord technical fields, are specifically a kind of new PVC power cords.
Background technology
Power cord is the electric wire for transmitting electric current.The mode of usual electric current transmission is point-to-point transmission.Power cord is according to purposes
Can be divided into AC AC power cords and DC direct current supply lines, usual ac power cable be by the wire rod of the higher alternating current of voltage,
This kind of wire rod needs unified standard acquisition safety certification side that can formally produce since voltage is higher.And DC lines substantially pass through electricity
Relatively low direct current is pressed, therefore AC lines are not stringent for requirement in safety, but for the sake of safety, various countries still require to unite at present
One safety certification.
For some chemical enterprises, since its internal environment is severe, needing requirement for the selection of power cord, its is corrosion-resistant
Property, mechanical strength and insulating capacity will height, and it is existing meet its requirement power cord cost it is higher, brought to enterprise in cost
Burden.
Utility model content
The purpose of this utility model is to provide a kind of new PVC power cords, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical solution：
A kind of new PVC power cords, including conductor, the first PVC sets, the 2nd PVC covers and inner sheath, outside the conductor
Surface is coated with insulating layer, and the outer surface of insulating layer is coated with inner sheath, and inner sheath is located at the inside of the first PVC sets, the
The inner wall fixed bonding of one PVC sets has the 2nd PVC sets, and glass fibre is filled in the 2nd PVC sets.
As further program of the utility model：If the conductor is woven by carried interest filament.
As the utility model further scheme：The conductor is copper core or the wire of aluminium material.
As the utility model further scheme：The material of the inner sheath is igelite or polyethylene
Plastics.
Compared with prior art, the beneficial effects of the utility model are：Due to being provided with the first PVC sets and the 2nd PVC sets,
Multiple-protection when the first PVC covers breakage, is protected internal inner sheath by the 2nd PVC sets, is avoided due to power supply line length
The situation that time makes external PVC sets damaged and conductor is caused to leak out, and it is filled with glass fibers in the 2nd PVC sets
Dimension, therefore increase its insulation performance, heat resistance, corrosion resistance and mechanical strength, improve the security performance of power supply and use the longevity
Life.
Description of the drawings
Fig. 1 is a kind of schematic cross-section of new PVC power cords.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, sheet
Field those of ordinary skill all other embodiments obtained without making creative work, belong to this practicality
Novel protected scope.
, it is necessary to explanation in the description of the utility model, term " " center ", " on ", " under ", it is "left", "right", " perpendicular
Directly ", the orientation of the instructions such as " level ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position relationship, are only
The utility model must have specific with the device or element for simplifying description rather than instruction or hint meaning for ease of description
Orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.In addition, term " the
One ", " second ", " the 3rd " are only used for description purpose, and it is not intended that instruction or hint relative importance.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integrally
Connection；Can be mechanical connection or electrical connection；It can be directly connected, can also be indirectly connected by intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, can above-mentioned art be understood with concrete condition
Concrete meaning of the language in the utility model.
Referring to Fig. 1, a kind of new PVC power cords, cover the 3, the 2nd PVC sets 4 and inner sheath including conductor 1, the first PVC
2, coated with insulating layer, the outer surface of insulating layer is coated with inner sheath 2 for the outer surface of the conductor 1, and inner sheath 2 is located at described the
The inside of one PVC sets 3, the inner wall fixed bonding of the first PVC sets 3 have the 2nd PVC to cover 4, glass are filled in the 2nd PVC sets 4
Glass fiber；Due to being provided with the first PVC sets 3 and the 2nd PVC sets 4, multiple-protection, when the first PVC sets 3 are damaged, by the 2nd PVC
The inner sheath 2 of 4 pairs of inside of set is protected, and avoids causing to lead since power cord makes external PVC sets damaged for a long time
The situation that body drain goes out, and filled with glass fibre in the 2nd PVC sets 4, therefore increase its insulation performance, heat resistance, anti-corruption
Corrosion and mechanical strength improve the security performance and service life of power supply.
If the conductor 1 is woven by carried interest filament.
The conductor 1 is copper core or the wire of aluminium material.
The material of the inner sheath 2 is igelite or vinyon.
The operation principle of the utility model is：Due to being provided with the first PVC sets 3 and the 2nd PVC sets 4, multiple-protection, when the
When one PVC sets 3 are damaged, the inner sheath 2 that 4 pairs of inside is covered by the 2nd PVC is protected, and avoids making due to power cord use for a long time
The situation that external PVC sets are damaged and conductor is caused to leak out, and filled with glass fibre in the 2nd PVC sets 4, therefore increase
Its insulation performance, heat resistance, corrosion resistance and mechanical strength improve the security performance and service life of power supply.
