Small 3phase oil immersed distribution transformers

Low power three-phase oil distribution transformers are used for power supply in the distribution network and mainly in places with low load or low load density.

Small Power Transformers

All transformers which are in our range of product could be order as single phase or triple phase transformer according to requirement of customers. Single phase transformers that are taking to operation in transformers bank system (including three or four single phase transformers), has advantages than triple phase transformers according to shipping weight and dimensions limits, site location limits and network stabilities.

Special Cast Resin Transformers

These transformer types can be designed and manufactured for special purposes and upon customer request. The designing and manufacturing of this type of transformers is a complicated process.

Traction transformers

Traction transformers are always design and manufactured according to a specific railway system and based on detailed parameters which are applicable in electrical transportation industry to electrify the power lines stationary.

Transformer bushing insulators

For outdoor and indoor use, low voltage bushing insulator (250 to 6300 amps), medium voltage bushing insulator (10 to 45 kV), different creepage distances (16 to 31 mmkV)

Transformer Oil

Zangan Industrial Oil Re­fining Co. was founded in 2006 aiming at manufacturing insulating oil for transformer industries with current capacity of more than 12000 tons per year which can be increased to 16000 tons per year.
