Powering Cities, Empowering Global Rail Projects
Urban rail transit demands the highest standards of safety, stability, and continuity in power supply. As a key partner of Hefei Rail Transit Project, Anhui Changda Electric Equipment Co., Ltd. has supplied reliable oil‑immersed three‑phase transformers to support the safe and efficient operation of Hefei’s metro lines. This case demonstrates our capability to deliver industrial‑grade power equipment for critical infrastructure worldwide.
Why Rail Transit Chooses Oil‑Immersed Three‑Phase Transformers
For subway stations, traction substations, and distribution networks, transformers must operate continuously under heavy loads, harsh environments, and strict safety rules. Our oil‑immersed three‑phase transformers are widely used in rail projects for these core strengths:
- Excellent insulation and heat dissipation
Transformer oil provides reliable insulation and efficient cooling, ensuring stable performance under long‑term full load.
- Strong short‑circuit and overload resistance
Meets rail transit’s strict requirements for impulse current, voltage fluctuation, and continuous operation.
- Fully sealed structure for long service life
Leak‑proof, dust‑proof, and moisture‑proof, adapting to underground, humid, and high‑intensity operating environments.
- Low loss & energy saving
Reduces operating cost and supports green, low‑carbon urban transit development.
- Compliance with international standards
Designed and tested in accordance with IEC standards and rail transit specifications for global use.
Our Contribution to Hefei Rail Transit
We are proud to participate in the construction of Hefei Rail Transit, a landmark urban infrastructure project in Anhui Province, China. Our customized oil‑immersed three‑phase transformers are applied in station power distribution systems to:
- Provide stable voltage conversion for lighting, ventilation, escalators, and control systems
- Ensure 24/7 uninterrupted power supply for daily operation
- Support high safety, low noise, and environmental protection requirements
- Withstand long‑term heavy load and frequent load fluctuations
This project proves that Changda Electric’s transformers can meet the strict demands of key rail transit projects and operate reliably in real urban scenarios.
