This dry-type transformer series (30KVA to 100KVA) utilizes vacuum-cast epoxy resin technology, delivering exceptional insulation, moisture resistance, and fire safety. Its oil-free design eliminates leakage risks, making it eco-friendly and ideal for indoor applications like malls, schools, and high-rise buildings. The fully enclosed structure resists corrosion and dust, paired with Class F/H insulation for high-temperature tolerance and low energy loss. Low-noise operation (≤55dB), long-term overload capacity, and minimal maintenance ensure 30+ years of service life. Compliant with IEC standards, customizable voltage ratios, and optional IP55 protection rating adapt to harsh environments. A safe, energy-efficient, and maintenance-free power solution for modern infrastructure.

1. Extreme Fire/Explosion Resistance, Zero Oil Pollution Risk

Technical Breakthrough: The Epoxy Resin Cast Dry-type Transformer uses full epoxy resin casting insulation technology, completely replacing the insulating oil in traditional oil-immersed transformers. This eliminates risks of oil leakage, combustion, or explosion.

Competitive Edge: Compared to oil-immersed transformers, it requires no oil circuit maintenance and complies with the global UL 94 V-0 fire safety standard. It is ideal for high-fire-risk environments like subways, data centers, and hospitals.

2. Fully Sealed Structure, Corrosion & High-Humidity Resistance

Material Characteristics: The transformer's epoxy resin and flame-retardant filler composite creates a fully sealed insulation layer, blocking moisture, salt fog, and chemical gas penetration.

Application Value: Outperforming ordinary dry-type transformers, it withstands 95% high humidity (non-condensing) and chlorine corrosion, making it suitable for coastal industrial zones, petrochemical plants, or tropical regions with extreme humidity. It reduces the failure rate by over 70%.

3. Wide-Temperature Range Adaptability, No External Cooling Required

Temperature Stability: The epoxy resin material maintains mechanical and electrical performance stability between -40°C and 130°C, eliminating the need for fan or cooling systems.

Competitive Edge: Unlike conventional dry-type transformers (which rely on forced air cooling), it operates continuously in extreme conditions such as sub-zero environments (e.g., northern wind farms) or high-temperature settings (e.g., steel mills), reducing downtime caused by temperature fluctuations.

4. Superb Vibration & Mechanical Shock Resistance

Structural Design: Windings and cores are cast into an integrated "one-piece" structure via epoxy resin, enhancing vibration resistance by 300%. It withstands seismic activity, heavy machinery vibrations, or transportation shocks.

Application Scenarios: Outperforming the looser structure of ordinary dry-type transformers, it is ideal for mining sites, construction zones, or mobile equipment (e.g., emergency power vehicles), minimizing contact failure or component loosening due to vibration.

5. Environmentally Friendly, Zero Pollution, Green Certification Compliance

Environmental Benefits: The oil-free design eliminates soil/water pollution risks. Epoxy resin materials comply with RoHS and REACH standards, containing no heavy metals or hazardous substances.

Market Advantage: Compared to traditional oil-immersed transformers, it easily meets global green certification requirements (e.g., ISO 14001), making it suitable for cleanliness-critical facilities like food processing plants and hospitals.

6. Compact Design, Space & Installation Cost Savings

Size Efficiency: The dry-type structure eliminates the need for oil tanks, reducing volume by 30% and weight by 20% compared to oil-immersed transformers. This simplifies installation in space-constrained areas like underground parking lots or skyscrapers.

Cost Efficiency: No need for oil replacement or cleanup, resulting in a 40% reduction in lifecycle maintenance costs.
