Product Overview
The 600kVA / 800kVA / 1000kVA corrosion-resistant oil-immersed transformer is designed for medium-power distribution in environments with coastal humidity, salt spray exposure, and outdoor climate challenges.
Built with a reinforced tank structure, protective surface coating, and copper winding system, this transformer supports stable voltage output, reduced loss, and long-term operational reliability.
It is well-suited for coastal regions, ports, island power systems, industrial zones, and outdoor installations where corrosion resistance and environmental durability are essential.
Corrosion-Resistant Tank Design
Anti-corrosion coating and reinforced steel tank support long-term use in coastal and high-humidity environments.
Sealed Structure for Moisture Protection
Sealed oil tank construction helps limit moisture ingress and supports internal insulation stability.
Copper Winding Configuration
High-conductivity copper windings improve load handling capability and thermal stability.
Low-Loss Core Performance
Grain-oriented silicon steel core reduces energy loss and supports efficient operation.
Outdoor Durability
Designed for continuous outdoor use under salt spray, humidity, and temperature variation.
