4.Iron core

Core alignment with high-quality cold-rolled silicon steel material, 45 °miter joints structure, stem withinsulation tape binding, the core surface is sealed with insulating resin paint rust proof, clamps andfasteners surface treated with prevent corrosion.
In addition, the company also developed a multi-stage step-stack core technology, the core stackautomatically by the shear line, forming the core does not use the stack of yoke program, effectivelyreducing the load loss, load loss, no-load current and the core noise.

5.Lv fooled winding
For low voltage, high current coil, short circuit stress short-circuit its larger, while less low pressure turns,the greater the use of low-voltage electric current ampere-turns wound type whose more prominentissue is not stable, heat issues also need to focus on to consider, at this time use low-voltage foilwinding can better solve the problem, first of all there is no axial foil product axially winding turns anda helix angle, high and low voltage winding ampere-turns balance, axial stress is small transformershort circuit,Second, because the insulation is thin, the process can be easily set up multi-duct, coolingproblems are better solved. l plant low-voltage foil coils are produced on STOLLBERG automatic foilwinding machine automatic winding,Internal welding using the winding machine argon arc welding, highprecision, small resistance welding, no external welding process. DMD insulation layer using inter-winding, winding complete rear end portion sealed with a resin cured.

6.Hv casted winding
●Main material and characteristics:
Class F coil insulated copper wire as conductor, glass fiber and epoxy resin composite materials forinsulation, its coefficient of expansion similar to the copper conductor, with good impact resistancetemperature changes, crack resistance. Glass fiber and epoxy resin constituent all have self-extinguishing, it does not continue to burn, it does not produce toxic gases and pollute the environment.Epoxy resin has good insulating properties, particularly suitable for the production of high-voltage coillevel.
●Manufacturing process:
The windings wound on the high-accuracy winding machine, when windingpave cast grass fibre aroundthe external and internal of the windings, there be armed air passage for transformer of large capacity,Then dry it invacuum.The whole casting and olidifying process is performed according to the processcurve of casting control terminal, which transferred through computer network by process department,every process can be monitored momentarily and adjusted for the various surroundings. The preciseprocess ensures free bubble and free hole of winding.

7.Temperature control device and air cooling system

The shell makes further protection for transformer. For users option, the grade of protection has IP20、IP23, ect.and the material has sort of cold-rolled steel plates and stdainless steel plates, ect.
The low-voltage outgoing line can adopt the method of standard bus bar group outgoing line, outgoing onthe transverse side and upper part as well as the very method that designed by the users.
