In the structural and technical aspects, the iron core is not perforated and built with 45-degree mitered joints, with the limbs tied with semi-dry unidirectional weftless fiberglass adhesive tapes, having the characteristics of low height and low loss. Especially, thanks to the automatic processing line of silicon steel sheet, the shearing burr is lower than 0.01 mm.
Low-loss small-and-medium sized oil-immersed transformers up to 35kV class are currently promoted by our company. The products, featuring leading technical parameters and structural design in China, have their unique features and are designed from the perspective of users.
The coil of each phase is subject to drying, compression, pressure test and height adjustment as per the process to ensure that the height of each coil meets the design requirements. The coils are dried with variable-pressure vacuum drying.
In order to reduce partial discharge and improve product reliability, the oil-filling process under vacuum, the vacuum requirement for oil filling, the evacuation time, and the oil filling speed are strictly controlled to ensure that the oil temperature is not lower than 60℃, and to avoid introducing gas during the oil filling process.
