Product Description
This eco-friendly power transformer utilizes natural ester (vegetable oil) as the insulating and cooling medium, specifically engineered to meet the rigorous demands of Vietnam’s tropical climate and grid conditions.
- Tropical Climate Adaptation: The high flash point of vegetable oil significantly reduces fire risks in hot environments, while the optimized cooling channels and radiators ensure stable operation even under Vietnam’s high ambient temperatures.
- Grid Compatibility (11kV/0.4kV): Designed strictly for the standard Vietnamese distribution voltage levels, ensuring seamless integration into local 11kV networks with reliable 0.4kV output.
- Moisture & Insulation Resistance: The specialized insulation paper and laminated boards offer superior moisture tolerance compared to mineral oil, protecting the core against humidity-related degradation common in Southeast Asia.
- Safety & Environmental Protection: Features a highly sealed tank to prevent leakage and contamination. The biodegradable oil minimizes environmental impact, making it ideal for urban or sensitive areas in Vietnam.
