High-temperature 2

Environmentally friendly: Made from renewable, biodegradable vegetable oil that degrades over 98% within 21 days, posing no risk to the environment or human health.
High fire safety: With an ignition point of 360°C and flash point of 330°C, it far outperforms traditional mineral oil transformers, which can ignite at just 150–200°C.
High overload capacity: Temperature rise is increased by 10K to meet distribution network overload demands without compromising normal service life.
Low noise: Operates at least 2dB quieter than mineral oil transformers and approximately 10dB quieter than dry-type transformers.
Extended service life: Vegetable oil slows insulating paper aging by 5–8 times compared to mineral oil, extending transformer lifespan by 33% — up to 30–40 years.
Superior moisture resistance: Voltage withstand levels remain unaffected until water content exceeds 800mg/kg, far higher than the 40mg/kg critical threshold of mineral insulating oil.

Ideal use cases:
- High environmental protection zones such as water sources and scenic areas
- High-safety requirements areas such as streets, urban villages, and densely populated locations
- High load rate environments such as industrial facilities and commercial plazas
- Areas prone to frequent overload
Installation environment: Suitable for indoor or outdoor installation at elevations up to 1,000m.
Temperature range:
- Maximum ambient temperature: +40°C
- Maximum daily mean temperature: +30°C
- Maximum annual average temperature: +20°C
- Minimum temperature: -25°C
Custom configurations are available for special operating conditions upon request.
