Features
Excellent Safety & Fire Resistance: Free of flammable oil, it significantly reduces the risks of fire and explosion, making it a safe choice for indoor installation scenarios close to personnel and sensitive equipment.
Environmentally Friendly: It contains no hazardous oils, completely eliminating the risk of soil or water contamination, and is a clean and sustainable electrical equipment.
Low Maintenance Cost & High Reliability: The solid insulation system does not require regular oil testing or replacement, which not only reduces the whole-life maintenance cost but also maximizes the equipment's operational uptime.
Robust & Durable Structure: The windings adopt Vacuum Pressure Encapsulation (VPE) technology, combined with high-quality insulation materials such as epoxy resin. This effectively resists the impact of moisture, dust, and corrosive environments, extending the equipment's service life.
Compact Design & Easy Installation: Compared with oil-immersed transformers of the same capacity, it is usually smaller in size and lighter in weight, offering higher flexibility in placement and convenient deployment even in confined spaces.
☆Ambient temperature: -25℃-40℃(can be customized according to the customer's environment)
☆Altitude: less than 1000 meters.(High altitude products can be customized)
☆Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
Here are some key points about dry type transformers:
Insulation technique: Dry type transformers employ insulation materials like polyester varnish or epoxy to insulate windings and the core and also to seal the core & coils and keep moisture out.
Cooling mechanism: Cooling fans regulate temperatures to prevent overheating. They use natural convection and forced air cooling to manage thermal conditions.
Fire safety: An inherent advantage of dry type transformers is their superior fire safety compared to oil-filled transformers. The absence of flammable oil significantly minimizes the risk of fire.
Indoor installation suitability: Dry type transformers are particularly suitable for indoor installations since there are no containment requirements like there are for oil-filled transformers.
Maintenance: There’s no need to monitor or replace oil levels, simplifying maintenance procedures.
Environmental considerations: Dry type transformers are more eco-friendly since there is no chance of oil contaminating the soil or water.
Applications: Dry type transformers find extensive utility in commercial structures, industrial complexes, medical institutions, educational establishments and other settings where prioritizing fire safety and environmental integrity is imperative.
Voltage and power ratings: Dry type transformers are available in various voltage and power classifications, rendering them adaptable for diverse application scenarios.
