The present invention proposes a kind of electromagnetic wire that water resistance is good, including the metal wire of several Spiral distributions, be wrapped in it is several with and metal wire on the outside of the second protective layer, the polyimide layer being arranged between the first protective layer, the first protective layer and the second protective layer that wrap up on the outside of the second protective layer, the nonwoven layer wrapped up on the outside of the first protective layer.A kind of good electromagnetic wire of water resistance of the invention; it is simple in structure; a strata imide layer is provided between the protective layer of two layers of rubber material; improve the insulation performance of conducting wire; it is coated with hydrophobic layer on the outside of first protective layer; the water resistance of conducting wire is improved, outermost is provided with nonwoven layer, is convenient for printed mark.
Description
Technical field
The present invention relates to a kind of electromagnetic wires, and in particular to a kind of electromagnetic wire that water resistance is good.
Background technology
Common winding wire can only coiling routine transformer, reactor and electrical-coil, it is by wrapped mode general
Insulating paper, film, braid over braid etc. are directly coated on conductive surface, and firm cohesive force, institute are not set up between conductor and insulating layer
With common winding wire is more open in structure, and insulation withstanding voltage ability is relatively low, especially insulate in wet condition
Humidity influence, which cannot be resisted, so that insulation performance is declined rapidly.Electrical-coil longtime running and when being used under some particular surroundings
It is higher to the water resistance of coil, high withstanding voltage Capability Requirement, the mechanical performance and electric property of product are improved, lightweight is selected
Quality material, researching and developing a kind of compound inslation, water proof wire just becomes the main problem that should currently solve.
Invention content
To solve the above-mentioned problems, the present invention proposes a kind of electromagnetic wire that water resistance is good.
The technical scheme is that：A kind of electromagnetic wire that water resistance is good, including the metal wire of several Spiral distributions,
Be wrapped in it is several with and metal wire on the outside of the second protective layer, wrap up on the outside of the second protective layer the first protective layer, the first protection
The nonwoven layer of the polyimide layer, the first protective layer outside package that are arranged between layer and the second protective layer.
Further, first protective layer is rubber material, and hydrophobic layer is coated on the outside of the rubber material.
Further, second protective layer is rubber material.
Further, the thickness of the polyimide layer is 0.2-0.3 millimeters.
Further, the metal wire is copper wire.
Advantageous effect
A kind of good electromagnetic wire of water resistance of the invention, it is simple in structure, it is provided between the protective layer of two layers of rubber material
One strata imide layer improves the insulation performance of conducting wire, is coated with hydrophobic layer on the outside of the first protective layer, improves the water proofing property of conducting wire
Can, outermost is provided with nonwoven layer, is convenient for printed mark.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
In figure, 1- metal wires, the first protective layers of 2-, the second protective layers of 3-, 4- polyimide layers, 5- nonwoven layers.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the present invention.
As shown in Figure 1, the electromagnetic wire that a kind of water resistance is good, if including several Spiral distributions metal wire 1, be wrapped in
It is dry with and second protective layer 3 in 1 outside of metal wire, 3 outside of the second protective layer the first protective layer 2,2 and of the first protective layer that wrap up
The nonwoven layer 5 of the polyimide layer 4,2 outside package of the first protective layer that are arranged between second protective layer 3；Described first protects
Sheath 2 is rubber material, and hydrophobic layer is coated on the outside of the rubber material；Second protective layer 3 is rubber material；It is described
Polyimide layer 4 thickness be 0.2-0.3 millimeters；The metal wire 1 is copper wire.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, according to the technical essence of the invention
To any simple modification, equivalent change and modification made by above example, in the range of still falling within technical solution of the present invention.
