Coastal Environment Solutions
High Humidity & Salt Corrosion
Enhanced anti-corrosion coating, reinforced sealing design, and high-quality gasket materials prevent moisture ingress and rusting. Strengthened tank welding avoids oil leakage.
Unstable Grid & Voltage Fluctuation
Strong overload capacity and stable voltage regulation performance. Tap changer options help adapt to voltage variation in island grids.
High Ambient Temperature
Optimized cooling design and sufficient oil volume ensure safe temperature rise control and long insulation life in 35-45°C tropical conditions.
Difficult Maintenance on Islands
Low-loss core design reduces heat stress. High-quality components extend service life and minimize maintenance frequency in remote locations.
Frequently Asked Questions
Is this transformer suitable for coastal or island environments?
Yes. It is specially designed with anti-corrosion coating and sealed structure for high humidity and salt spray conditions.
Can it operate under high ambient temperature?
Yes. The transformer is designed to operate safely up to 45°C ambient temperature.
Can voltage be customized?
Yes. Voltage ratio can be customized according to your local grid requirements (e.g., 22kV/0.4kV, 33kV/0.4kV).
What standards does it comply with?
We manufacture according to IEC standards. Other standards can also be customized upon request.
