Three phase oil immersed power transformer

The 110kV power transformer developed and produced by GE Transformer draws on advanced technology at home and abroad. Its reliability and performance have reached the international advanced level. It has the characteristics of environmental protection, economy, and strong stability. It is suitable for substations, power plants, large industrial and mining enterprises, etc. GE Transformer has the development and production capacity of 110kV power transformers, traction transformers, split transformers, and other standard and non-standard products. These excellent products have reached the international advanced level and have been widely used in the State Grid, China Southern Power Grid, and overseas power systems. We have won high recognition from market users and industry experts. With years of rich manufacturing and operation experience, we are committed to providing high-quality products and services for power systems.

1. Low loss
   The no-load loss is 15%-20% lower than the national standard GB64511, and the load loss is 5% lower than the national standard GB6451-2008.
   2. Low noise
   The self-cooling noise level will reach below 60dB, which is nearly 20dB lower than the national standard and can be specially designed and manufactured with lower noise levels if users have special requirements.
2. Low local discharge
   The whole process of 110kV products will be dust-free, and all metal and insulating parts inside the body will be rounded so that the amount of local discharge will be controlled below 100pc.
3. High short-circuit resistance
   110kV transformers are certified to have strong short-circuit resistance and reliability.
4. Beautiful appearance
   Full polishing and grinding to remove rust, powder electric spray paint can reach the effect of appliance spray paint, wide piece radiator.
5. No leakage
   All seals are made of acrylate material and adopt one-time molding technology, with no interface.

• Insulation
  High-temperature resistant hybrid insulation system winding.
• Coils
  High-voltage coils of small and medium capacity are tangled one by one continuous type, and large easy for the inner screen one by one continuous type, in order to improve the longitudinal capacitance distribution of the coil under the shock voltage; coils are guided oil circulation structure, reduce the temperature rise of the winding, product design life of 30 years.
• Iron core
  High permeability voltage-oriented cold-rolled silicon steel sheet will be used, non-porous tying, frame structure, D-shaped iron yoke structure for the coil to provide a large area platform, step-level seam. Swiss imported automatic shearing and stacking robots ensure that the burr of the core is less than 20µm, and the multi-stage seam of the core reduces the no-load loss and lowers the no-load current and noise level.
• Oil tank
  Minute cover type and barrel type structure. All seals are stop-hole limit seals; all metal parts inside and outside the tank are rounded and deburred, welds and seals are leak tested three times (fluorescent, positive pressure, and negative pressure leak tests); paint is made according to the rust-proof requirements of home appliances.
