110kV Class Power Transformer

The 110kV class oil-immersed energy-saving transformers produced by our company feature low losses, low noise, low temperature rise, high reliability, as well as core-hanging-free and leakage-free design. All performance indicators have reached the advanced level of the industry. These transformers can significantly reduce grid losses and operating costs, delivering substantial economic benefits. They are suitable for power plants, substations, new energy wind power and photovoltaic power stations, as well as large industrial enterprises such as mines and petrochemical plants.
The 110kV class product series covers a full range of products including various insulation levels, various frequencies, tie transformers, and testing transformers, both for domestic and international applications.

The high-voltage winding adopts an inner-screen continuous or continuous structure, improving the impulse distribution of the winding.

The low-voltage winding for capacity range of 6300~80000kVA adopts a cylindrical or helical structure, featuring high mechanical strength, balanced ampere-turn distribution, and strong short-circuit withstand capability.

The active part is equipped with a positioning mechanism to prevent displacement during transportation. At the same time, locking nuts are added to all fasteners to ensure they do not loosen during long-term operation, meeting the requirement of core-hanging-free design.

The core adopts a full-miter step-lap stacking method using high-quality cold-rolled grain-oriented silicon steel sheets.

The product surface is treated by degreasing, derusting, and sandblasting, followed by the application of primer and topcoat, meeting the special requirements for use in metallurgical, petrochemical systems, and damp, polluted areas. The product features excellent appearance, small size, and small installation footprint, making it an ideal maintenance-free product.
