Core Technologies & R&D Strength

Low-Loss Design

Optimized magnetic circuit design and high-performance silicon steel sheets enable oil-immersed and dry-type transformers to reduce no-load losses by 15–20% and load losses by 10–15% , resulting in higher operating efficiency.
High Reliability Design

Oil-immersed, dry-type, and pad-mounted transformers have passed short-circuit, overload, and vibration tests. With an annual product failure rate of less than 0.05% , they ensure long-term stable and reliable operation.
High-Temperature Tolerance

The windings and insulation systems of dry-type and prefabricated box-type transformers have undergone 1,000 hours of continuous operation testing at 95°C , ensuring stable and reliable performance under high-temperature conditions.
Integrated Smart Monitoring

Transformers with intelligent measurement and control systems monitor voltage, current, and temperature in real time, with remote diagnostics responding in under 1 second to ensure optimal efficiency.
Material Innovation

High-quality silicon steel sheets and advanced insulation materials significantly enhance oil-immersed and dry-type transformer performance, extending service life by 20–30% and increasing efficiency by 5–8%.
