Active Part Insulation
The core is made of high quality cold rolled grain oriented high permeability silicon steel sheet, silicon steel sheet by the Swiss introduction of the shear line cutting, shear burr is not greater than 0.02mm. Advanced core stacking turntable, the domestic first-class non-stacking yoke process, reducing the silicon steel sheet excess handling process, fully guarantee the performance of cold-rolled silicon steel sheet, effectively reducing the transformer no-load loss. Reasonable design clip, pull the board, the beam, pad feet, making it a solid whole, to ensure that the core film in the best state of force. Not only reduces the no-load loss, but also greatly improves the transformer no-load performance. Core structure according to the design needs can be single-phase double column, single-phase three-column, single-phase four-post, three-phase three-column, three-phase five-column structure, at the same time according to the needs of the process, the core film stack can be used in general structure or frame structure.
Winding are wound on high-strength, ductile T4 cardboard tube. The high-voltage winding is made of high-density cable paper composite wire, which greatly reduces the eddy current loss of the wire. In the low-voltage winding using self-adhesive transposition wire wound, the inside of the auxiliary support to increase the wire support points, all winding have locking bars on the outside, and the winding are designed with “0” margin. All of the mats have been densely treated to greatly enhance the mechanical strength and short circuit resistance of the winding. In addition, the winding are equipped with oil-oriented structure, improve the oil flow path, reducing the warmest winding temperature rise, and slow down the aging of the insulation, extending the life of the transformer. Reasonable choice of winding form, high voltage winding with inner screen continuous winding, reduces the welding process in the welding point, so that the transformer operating failure rate greatly reduced. Reasonable distribution of the winding between the ampoule distributions, reducing the imbalance caused by the ampoule of the lateral magnetic flux leakage, improves short-circuit resistance of winding.

Active Part Insulation
The active part assembly and coil winding are completed in the fully enclosed purification plant. At the same time the use of kerosene gas drying process, drying process with kerosene vapor washed back to the transformer active part impurities, the product cleanliness effect is better, drying efficiency is also greatly improved.
Transformer active part using advanced integrated phase set technology, all the winding alone dry, separate the height and then bake, after all the coil assembly and then dry again, three times drying, three times to adjust the height, ensure uniform height of the winding, reducing short-circuit mechanical force.
The lower part of the active part pallet and the upper pressure plate all use a high mechanical strength and good electrical performance electrical laminate. Transformer stays, pads, etc. have two times pressure and rounding process, reducing the partial discharge. According to the result of dynamic stability calculation, the number and
position of the pressure plate are arranged reasonably, so as to press the active part as much as possible to improve the overall stability of the active part. The upper and lower active part is made of steel positioning, to ensure that the active part can withstand a variety of transport conditions under the impact of the test and the operation of the axial electric power without displacement. The active part is used up and down the use of steel positioning to ensure that the active part can withstand a variety of transport conditions under the impact of the test and the operation of the axial electric power without displacement, so that the scene is not hanging. Just do a simple transfer acceptance test, the product can be put into operation.
Reasonable layout of the transformer lead, take shape beautiful, to ensure adequate electrical strength and mechanical strength, widely used cold welding, all welding all metal shield, the effective control of the transformer partial discharge.
