Why Choose Our 200kVA Oil-Immersed Transformer

This overview breaks down the six pillars of excellence that define our Oil Immersed Transformer, moving beyond basic specifications to highlight the tangible benefits you receive.

Superior Efficiency & Reduced Operating Cost

At the heart of our 200KVA oil immersed transformer is a core built from high-grade, cold-rolled, grain-oriented silicon steel. This advanced material, combined with precisely wound low-resistance copper conductors, minimizes energy loss. The result is significantly lower no-load and load losses, which translates directly into reduced electricity bills and a lower total cost of ownership over the decades-long lifespan of the unit.

Unmatched Durability for Harsh Environments

We construct the main tank of our 200KVA oil immersed transformer from reinforced steel plate, protected by a robust, multi-layer anti-corrosion coating. This defense system is engineered to resist rust and degradation caused by moisture, salt spray, and industrial pollutants, ensuring the transformer’s structural integrity and long service life even when installed in challenging outdoor or coastal environments.

Reliable Insulation & Efficient Cooling System

The combination of high-grade dielectric oil and a meticulously designed radiator bank creates a highly effective closed-loop system. This ensures optimal heat dissipation from the core and windings, maintaining stable operating temperatures under full load. This efficient thermal management prevents premature aging of the insulation, directly contributing to the exceptional reliability and extended operational life of the 200KVA oil immersed transformer.

Integrated Safety & Monitoring Features

Your peace of mind is engineered into our design. Critical accessories like the Buchholz Relay provide immediate detection of internal faults, while the Oil Level Indicator allows for easy visual monitoring. The Druckentlastungsvorrichtung and Silica Gel Breather work in tandem to protect against over-pressure and maintain oil purity. These features make our 200KVA oil immersed transformer a safe and intelligent choice for your power network.
