Abstract
The utility model provides a single-side film mica tape lapped copper flat wire, which comprises a copper flat conductor and an insulating layer for wrapping the copper flat conductor, wherein the insulating layer is formed by lapping a polyimide film reinforced little rubber powder mica tape on the copper flat conductor. The utility model also provides a making method of the single-side film mica tape lapped copper flat wire. The method comprises that the mica tape is lapped on the copper flat conductor to form the copper flat wire. The copper flat wire not only has the advantages of high temperature resistance, corona resistance, good insulating performance and the like, but also has higher mechanical strength; and an insulating paint does not need to be coated in the making method of the copper flat wire, so that the cost is saved, and pollution in the making process is reduced. The copper flat wire can be widely applied to windings of high-voltage motors, lifting motors and other electrical appliances.
Description
Technical field
the utility model relates to a kind of electromagnetic wire, relates more specifically to a kind of wrapped copper strap wire of single-sided film mica tape that can be used for high-voltage motor, specific type of electric machine etc.
Background technology
electromagnetic wire is mainly used in the winding of transformer, motor and various electric equipments; Electromagnetic wire of the prior art is a coated insulation layer on conductor; Insulating barrier is generally glass fiber layer and/or other thin layers etc.; Product need be coated with steps such as insulating varnish, oven dry usually, and cost is higher, and pollutes bigger in the manufacturing process; Also exist single-face polyester film reinforcement dry mica paper tape and carry out the electromagnetic wire that wrapped conductor forms, tolerable temperature is not high enough, the not high shortcoming of mechanical strength but this kind product exists.
Summary of the invention
are for overcoming the problems referred to above of the prior art, but the utility model provides the wrapped copper strap wire of single-sided film mica tape that is applicable to high-voltage motor, specific type of electric machine and electrical equipment winding coil of a kind of withstand high temperatures, anti-corona.
The technical scheme that
the utility model adopts is: the utility model provides a kind of single-sided film mica tape wrapped copper strap wire; Comprise copper flat conductor and the insulating barrier that coats this copper flat conductor, wherein insulating barrier is wrapped on the copper flat conductor and form by polyimide film reinforcement dry mica paper tape.
further, the width a of copper flat conductor longitudinal section is 1.00～5.60 mm, length b is 3.55～16.0 mm.
Further, the thickness A-a of insulating barrier does
Mm is preferably 0.50 mm.
further, the thickness A-a of insulating barrier is 0.40 ± 0.02 mm, is preferably 0.40 mm.
more further, the thickness A-a of insulating barrier is 0.43 ± 0.02 mm, is preferably 0.43 mm.
wherein, the thickness A-a of insulating barrier is the thickness of insulating barrier on short transverse.
further, the temperature that this copper strap wire can tolerate is 180～200 ℃.
compared with prior art; The utlity model has advantage: copper strap wire that the utility model provided adopts polyimide film reinforcement dry mica paper tape wrapped on the copper flat conductor and form; This kind copper strap wire has high temperature resistant, anti-corona and mechanical strength advantages of higher; This kind copper strap wire that the utility model provided need not be coated with insulating varnish on copper conductor; Cost-saved, reduce the pollution in the manufacturing process, in the winding of the wrapped copper strap wire of single-sided film mica tape applicable to high-voltage motor, specific type of electric machine and other electrical equipment etc. of the utility model.

Embodiment
Set forth the preferred embodiment of the utility model below in conjunction with accompanying drawing in detail
; Thereby, advantage of the utility model and characteristic more remove clear and definite defining so that being easier to it will be appreciated by those skilled in the art that the protection range of the utility model made.
Fig. 1 to Fig. 2 is consulted in
; The wrapped copper strap wire of a kind of single-sided film mica tape of the utility model; Comprise copper flat conductor 1 and the insulating barrier 2 that coats copper flat conductor 1, insulating barrier 2 forms on copper flat conductor 1 by polyimide film reinforcement dry mica paper tape is wrapped.The width a of copper flat conductor 1 longitudinal section is 2.24 mm, and length b is 7.10 mm, and the thickness A-a on the short transverse of insulating barrier 2 is 0.43 mm.The temperature that the wrapped copper strap wire of single-sided film mica tape of the utility model can tolerate is 180～200 ℃; And the temperature that the wrapped copper conductor of single-face polyester film reinforcement dry mica paper tape in the past can tolerate is about 150 ℃; Obviously the copper strap wire of the utility model can tolerate higher temperature; Simultaneously also have higher mechanical strength, more be applicable to high-voltage motor, lift and electrical equipment winding coil etc.
above specific embodiment to the utility model is illustrated; But the protection content of the utility model is not only limited to above embodiment; In the affiliated technical field of the utility model; The common knowledge of GPRS just can be carried out diversified change in its technological main idea scope.
