Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. According to the way of cooling, it can be divided into: Dry-Type Transformer and Oil-Immersed Transformer. For Dry-Type Transformer it is relying on air convection for natural cooling or add fan cooling. For Oil-Immersed Transformer it is means oil is used as cooling medium, such as oil-immersed self-cooled, oil-immersed air-cooled, oil-immersed water-cooled, forced circulation oil cooling, etc.

The LSF series, LSS series and LSX series combined oil-cooling devices provided by Joule Tech for transformers can meet the cooling requirements of various voltage levels and different types of oil-immersed transformers, and can be specially designed according to the requirements of clients.
