Dry Type Transformer – ATS Power Ltd
A Dry Type Transformer is an electrical transformer that uses air instead of liquid coolant (like oil) to dissipate heat. The windings are insulated with epoxy resin or other dry insulating materials, making it safe, reliable, and environmentally friendly. Dry type transformers are ideal for indoor applications where fire safety and low maintenance are critical.
At ATS Power Ltd., we provide high-quality dry type transformers designed to meet industrial, commercial, and utility requirements with maximum efficiency and durability.
Advanced Features of Dry Type Transformers
Oil-Free Design
Dry type transformers do not use any oil or liquid coolant. This eliminates the risks associated with flammable liquids such as fire hazards, spills, and environmental damage. It’s a safer and cleaner alternative to traditional oil-filled transformers.
Enhanced Safety
Constructed using fire-retardant materials and fully enclosed windings, these transformers offer superior resistance to fire and thermal stress. The chances of explosions or toxic leaks are drastically reduced, making them ideal for indoor and high-risk environments.
Low Maintenance
With no moving parts or oil that needs testing and replacing, dry type transformers require very little maintenance. This significantly reduces operational costs and downtime, while ensuring continued performance over the years.
Environmentally Friendly
Free from oil and harmful coolants, dry type transformers are environmentally safe. There is zero risk of groundwater contamination or toxic emissions, supporting your organization’s sustainability goals and green initiatives.
Lightweight & Compact Design
Dry type transformers are more compact and easier to transport or install. Their smaller footprint makes them perfect for urban facilities, tight electrical rooms, or space-limited installations.
Excellent Heat Dissipation
Thanks to advanced epoxy resin insulation and optimized air-cooling systems, these transformers manage internal temperatures effectively. The result is reliable operation even under continuous or high-load conditions, extending equipment life.
High Reliability in Harsh Conditions
Designed to perform reliably in extreme operating environments — including dust, moisture, vibration, and fluctuating temperatures — dry type transformers ensure uninterrupted power for critical operations.
