Abstract
The utility model relates to an insulating material for an electromagnetic wire. The insulating material comprises a mica insulating layer, a first gluing layer, a second gluing layer, a first polyester film and a second polyester film, wherein the first gluing layer, the first polyester film, the mica insulating layer, the second polyester film and the second gluing layer are sequentially laminated, and the thickness of the mica insulating layer is 0.04 to 0.07 mm. Conducting wires wrapped by the insulating material provided by the utility model have the advantage that the corona resistance capability, the insulation performance, the heat insulation performance and the chemical stability are respectively and obviously improved.
Description
Technical field
The utility model relates to a kind of power equipment and holds material, relates in particular to a kind of electromagnetic wire and uses insulating material.
Background technology
Electromagnetic wire is in order to the coil in the manufacturing electric product or the insulated electric conductor of winding, claims winding wire again.By its basic composition classification, electromagnetic wire can be divided into conducting wire center and electric insulation layer.Usually be divided into enamelled wire, lapped wire, enamel-cover lapped wire and inorganic insulated wire according to electric insulation layer used insulating material and manufacture.
Paper covered wire; Belong to lapped wire; It is the lead of handling through the mould extruding or the drawing after annealing of certain specification by oxygen-free copper bar or round aluminum rod; The winding wire of wrapped two-layer or two-layer above insulating paper (comprising telephone paper, cable paper, high-tension cable paper, turn-to-turn insulation paper etc.) on copper (aluminium) conductor again is applicable to that oil-filled transformer coil and other similar electrical equipment winding use line.Wherein, NOMEX paper covered wire is electromagnetic wire comparatively commonly used; It by the wrapped winding wire that forms of the NOMEX insulating paper of du pont company production, is mainly used in transformer again by oxygen-free copper bar or the round aluminum rod lead through the mould extruding of certain specification; Electric welding machine, electromagnet or other similar electric equipment product winding.The film lapped wire is more a kind of electromagnetic wire of development in recent years, mainly contains polyester film and polyimide film lapped wire.
For using the electromagnetic wire that electric product is made, its tolerance under high voltage to corona and puncture, and chemical resistance etc. is also most important under particular surroundings.
The utility model content
The purpose of the utility model is to provide a kind of electromagnetic wire to use insulating material, improves insulation, thermal insulation and the chemical stability of insulating material.
A kind of electromagnetic wire that the utility model provides is used insulating material, comprises mica insulation layer, first adhesive layer, second adhesive layer, first polyester film and second polyester film.First adhesive layer, first polyester film, mica insulation layer, second polyester film and second adhesive layer stack gradually.
The utility model insulating material is provided with the mica insulation layer between laminated polyester film, improved insulating material to the corona tolerance, has also improved caking property and agglutinating property.Its thickness is generally 0.02-0.03mm.
The thickness of first polyester film and second polyester film is respectively 0.01mm.
First adhesive layer makes the utility model insulating material be bonded in metallic conductor, is beneficial to film band thermally equivalent.First adhesive layer is related to the loss of conductor to the heat transfer rate and the heat of thin layer, and its thickness is 0.007-0.02mm.
Second adhesive layer is related to each and holds the bonding between the lead, and to avoid slippage, its thickness is generally 0.004-0.01mm.
The insulating material that provides through the utility model holds the lead of processing, and it is significantly increased to corona tolerance, insulating properties, thermal insulation and chemical stability.
In addition, laminated polyester film provides effective protection to the mica insulation layer, has improved the bending and the intensity of insulating material.First adhesive layer makes film band bonding earlier and fits in metallic conductor fully, and it is more even that thin layer is heated, and effectively improved the effect that holds of conductor, reduces the breakage that holds material greatly, has strengthened the homogeneity of wire insulation.It is bonded to each other that second adhesive layer makes each hold lead, avoided slippage and mutually between the generation of slide relative, help protection to thin layer.
Description of drawings
Fig. 1 is the structural representation of the utility model electromagnetic wire with insulating material one embodiment.
Embodiment
Describe the technical scheme of the utility model in detail below in conjunction with accompanying drawing.The utility model embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of utility model, and not break away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the claim scope of the utility model.
Fig. 1 is used for the structural representation of electromagnetic wire with insulating material one embodiment for the utility model.As shown in Figure 1, the utility model comprises mica insulation layer 1, first adhesive layer 2, second adhesive layer, 3, the first polyester films 4 and second polyester film 5.First adhesive layer 2, first polyester film 4, mica insulation layer 1, second polyester film 5 and second adhesive layer 3 stack gradually.The thickness of mica insulation layer is 0.02mm, and the thickness of first adhesive layer is 0.007mm, and the thickness of second adhesive layer is 0.01mm.
The mica insulation layer has improved insulating material to the corona tolerance, has also improved caking property and agglutinating property.Laminated polyester film provides effective protection to the mica insulation layer, has improved the bending and the intensity of insulating material.
Conductor is because of after switching on; Than the first thin adhesive layer conductor energising back evolution of heat is also evenly passed to thin layer fast; Effectively improve the effect that holds of conductor, made the thin layer metallic conductor of fitting fully reduce the breakage that holds material greatly, strengthened the homogeneity of wire insulation.Relatively to make each hold lead bonded to each other for the second thicker adhesive layer, avoided slippage and mutually between the generation of slide relative, help protection to thin layer.
