Oil immersed transformers are voltage conversion devices that use oil to keep the transformer cool. This type of transformer structure is mounted in a welded steel oil tank filled with oil. Due to the liquid’s inflammability, oil-filled transformers are mostly used in outdoor installations. Oil-type transformers can be put on the ground, on a pad, or on a pole. They function well in various environments, including transmission and distribution lines, renewable energy generation, and small businesses.

 

S-35kV series oil immersed transformer produced by the company is suitable for three-phase AC 50 / 60Hz, rated voltage 35kV distribution grid, and plays an important role in high-voltage transmission and low-voltage power supply.

A dry type transformer is a motionless piece of equipment that uses environmentally acceptable temperature insulation systems. They are also known as “cast resin type transformers.” The transformer is housed in a case with adequate ventilation, Because of the cooling constraints, dry type transformers’ maximum voltage is restricted to 35kV. 
The scientific and reasonable design and casting process make the product have less partial discharge, lower noise and stronger heat dissipation capacity. Under the condition of forced air cooling, it can operate for a long time under 125% rated load. Dry type transformers have a wide range of commercial, industrial, and utility applications. They are commonly utilized in small and medium-voltage applications in electric equipment.
