Description

Our 110 kV oil-immersed power transformers are engineered with advanced design concepts and precision manufacturing, ensuring exceptional reliability, efficiency, and durability. With optimized winding structures, high-quality silicon steel cores, and enhanced mechanical reinforcement, these transformers deliver superior electrical performance and strong resistance to operational stresses.

They combine low loss, high efficiency, low partial discharge, and low noise operation, significantly reducing power grid losses and operating costs while supporting sustainable and long-term performance. Their compact, maintenance-free design makes them highly suitable for demanding environments where efficiency and stability are critical.

Applications

These transformers are widely deployed in power plants for stepping up generator voltages, in transmission and sub-transmission substations for stepping down high-voltage transmission to regional distribution levels, in renewable energy stations (wind and solar) to connect clean energy to the grid, and in large industrial enterprises such as steel, mining, petrochemical, and heavy manufacturing, where high-capacity and stable power supply is essential.

Advantages

• High Efficiency & Low Loss: Reduces grid losses and operating costs, maximizing economic benefits.

• Strong Short-Circuit Resistance: Optimized winding structures and robust mechanical design ensure stability under electrical and mechanical stresses.

• Durability in Harsh Environments: Advanced surface treatments (degreasing, sandblasting, anti-rust coating) extend service life.

• Compact & Space-Saving: Designed for efficient installation, ideal for plants, substations, and industrial sites with limited space.

• Low Noise & Low Partial Discharge: Improves operational reliability and ensures compliance with modern environmental standards.

• Maintenance-Free Operation: Built for long-term stable service with minimal maintenance requirements.

• Versatile Applications: Power plants, transmission substations, renewable energy stations, and energy-intensive industries.
