Iron Core
The iron core is made of high quality cold silicon steel sheet with 45°sloping seam, its barrel is strapped with insulated tape, and it is sealed with resin to be safeguard ed an against corruption and moisture, the clamping parts and fastener are corruption-proof followed by superficial treatment.
In addition GanDian have exploited multi-steeping laminated core technology, the core is self-stackes by shearing line, the iron molding adopts non-laminated upper yoke to reduce the no-load loss, no-load current and iron noise.Characteristics
It is safe, non-pollute, and flame proof which can be installed directly on the load center with the merits of free maintenance, easy installation, low combined operationcost, low loss and excellent humidity resistance. The transformer can be operated normally under 100% humidity and put into motion without dry in advance when out of use it shares the properties of low partial electricity local discharge, low noise and large heat dispel capability, it can be operated with the rated load of 150% under the forced air cooling conditions. With perfect temperature protect control system to ensure safety operation of the transformer referring to the operation research of 10 thousand transformers have been put to use, their reliability norm have reached advanced intemational standard.HV Casted Winding Main material and characteristics:
The coil adopt copper wire as the windings conductor, glass fibre and epoxy resin composite as insulation, whose coefficient of expansion is close to the copper conductor with the merits of excellent shock resistance, high temperature adaptive faculty and nice shattering resistance. The compositions of glass fibre and epoxresin have the best properties of high fire resistance, which will never outcome poisonous pollution.LV Foiled Winding
For LV and heavy current winding, its short-current stress is very large and low voltage turn is small at the same time, the heavier the low voltage current is the more prominent the problem of non-stability yon ampere-turn which adopting wire-wound will be, and moreover, the heat dispersion should be considered, but the above problem can be better solved by adopting foil winding, at first, there has been no axial turns and axial winding helix angle for foil products, the ampere-turn of high/low voltage winding is equal and the axial shortcurrent stress is small. Secondly, due to the laminated insulation, it is easy to set up multi-level air passage as per its technology, so is the problem of heat diversion, Our foil winding auto wound on the auto foil winding machine, which supplied by France STOLLBERG Coporation,adopts protective internal welding with argon, with the excellent propertines of high accuracy, low welding resistance and non extemal welding process. The interlayer of winding in sulateDMD, the extreme end is sealed and soildified by resin.
