Varelen manufactures cast resin dry type transformers power up to 25 MVA and with voltage up to 36 kV.
Our factory has both technology “cast resin ” and “vacuum pressure impregnation” which are used in manufacturing. offers a cast resin transformers production with copper and aluminium windings and the option of embedding with a Class F or Class H (180°C) system.
The partial discharge parameter that specifies the transformer lifetime is <5 pC in our dry type transformers.
As an advanced power equipment, dry-type transformer has many advantages in the context of energy transformation, and provides important support for sustainable energy development and stable operation of power system.
