An insulation system without transformer oil
Dry-type transformers use air and solid insulation systems rather than an insulating-liquid tank. This removes oil-handling tasks and the risk of insulating-oil leakage associated with liquid-filled equipment.
Common applications
Typical locations include commercial buildings, industrial facilities, schools, hospitals and transport infrastructure. Dry-type equipment can also be considered for renewable energy installations where its configuration meets the duty.
Environment and maintenance
Suitable ventilation, temperature monitoring and attention to contamination are important. The required insulation system, cooling arrangement and environmental rating should be agreed for the actual installation conditions.
