6. FAQ (Frequently Asked Questions)

Q1: What is the difference between 10kV 440V transformers and conventional 10kV 400V transformers?

The core difference lies in low-voltage output standard and application scenarios. Conventional 10kV 400V oil immersed transformers are suitable for domestic civilian and ordinary industrial equipment with 400V voltage standard, while this 10kV 440V dedicated transformer adopts customized winding ratio to stably output 440V voltage, which is specially tailored for imported equipment and international standard electrical devices. Using a 400V transformer for 440V equipment will cause long-term under-voltage operation, resulting in reduced equipment efficiency, frequent failure and even burnout. This 440V dedicated model can perfectly match international industrial power standards and ensure normal and efficient operation of special equipment.

Q2: How to choose capacity from 125kVA, 160kVA and 200kVA for industrial projects?

Capacity selection needs to be based on actual continuous operating load and future expansion plan. The 125kVA model is suitable for small workshops and light-load industrial scenarios with low total power consumption, featuring lower no-load loss and better energy-saving effect under light-load operation. The 160kVA capacity is the most cost-effective universal model, which can meet the power demand of most conventional medium-small industrial projects and is the most widely used specification in industrial transformation projects. The 200kVA high-capacity version is recommended for production lines with frequent peak load surges and projects with later capacity expansion demands, reserving sufficient overload margin to avoid equipment overload tripping and later replacement.

Q3: Is the oil immersed structure suitable for long-term outdoor industrial operation?

Absolutely suitable. This series of 10kV 440V three-phase oil immersed transformers is optimized for long-term unattended outdoor industrial scenarios. The fully sealed corrugated oil tank structure effectively prevents moisture and dust from entering the interior, avoiding insulation aging and oil deterioration caused by long-term outdoor exposure. The ONAN natural oil circulation cooling system provides more stable heat dissipation than dry-type transformers, supporting long-term full-load continuous operation without overheating. In addition, the overall anti-corrosion and weather-resistant structure can adapt to high temperature, low temperature, humid and dusty industrial environments, with low failure rate and service life up to 25 years under standardized operation and maintenance.
