Along with electrical equipment and electrical advance by leaps and bounds development needs, the requirement for the properties of winding wire is also more and more higher.Such as in order to meet the needs of frequency control specific type of electric machine, improve stability and the useful life of electrical equipment and electrical performance further, we are once from Japan's a large amount of import composite bed electromagnetic wire, for the specific type of electric machine such as oil field, mine.
As everyone knows, there are many kinds although domestic at present with regard to enamelled wire, do not have one to be out of this world, always have its weak point.Even if QXY enamelled wire is described as all-round enamelled wire, but enamelling process amplitude is less, require high to conductive surface, the careless slightly properties that will have a strong impact on it in lacquering process, and this product price is more expensive, all these limits its extensive use.Therefore, how to meet the needs of specific type of electric machine, the winding wire that a kind of water resistance is good, insulation thickness is thin, withstand voltage height, cost are low is provided, has become the problem that industry is anxious to be resolved.
Utility model content
The utility model for the problems referred to above, object be to provide a kind of there is superior function F level water proof type polyester film sintering enamel-cover PET winding wire and.
The technical solution adopted in the utility model is for this reason: the utility model comprises the qzy180 level enamelled wire of bottom, and skin is hot melt adhesive mylar tape.
Described qzy180 level enameled wire coat insulation thickness is 0.07 ~ 0.10mm, and polyester film insulation thickness is 0.09-0.12mm.
The wrapped degree of overlapping 47-49% of described hot melt adhesive polyester film.
The wrapped number of plies of described hot melt adhesive polyester film is layer 2-3, degree of overlapping 47-49%, 1/3 bandwidth and seam staggers.
The preparation technology of F level water proof type polyester film sintering enamel-cover PET winding wire, carries out according to following steps:
1) polyester film is inside with the one side of hot melt adhesive, and 47-49% is overlapping wrapped to qzy180 level enamelled wire, Transposed wind and film joint smooth, seam staggers 1/3 bandwidth;
2) on vertical type enamelling machine, with softening furnace, wrapped good film envelope curve is carried out heat-sealing sintering, sintering temperature is 160-180 DEG C, speed of a motor vehicle 3.5-4.5 m/min.
The utility model is according to the technical requirement of design of electrical motor, and single coating can't resolve problem, can only select composite bed.Because composite bed then can reach the object of comprehensive properties of learning from other's strong points to offset one's weaknesses.High and use under high temperature, high humidity mal-condition according to requirement of withstand voltage, certainly will to design the electromagnetic wire that a kind of enamelled wire and film carry out composite insulation structure like this, just can meet the demands.Therefore through repeatedly Technological Experiment Scheme, a kind of F level water proof type polyester film sintering enamel-cover PET winding wire is obtained; Following performance is possessed: the performances such as 1) heat punching, flexibility and tack all reach the requirement of GB standard and technical protocol, and have certain nargin through experiment; 2) puncture voltage in water, technical protocol requirement >=3.0kv, reality can reach about 6.0kv.
