A Chinese company has installed a world-first 765 kV auto-transformer in Pakistan. The project marks a major step in the country’s power transmission development.
Landmark Installation in Mansehra
POWERCHINA completed the installation at the Mansehra substation. The transformer introduces advanced technology to Pakistan’s energy infrastructure.
This is the first transformer of its kind in the world. It uses constant-flux voltage regulation to improve efficiency and performance.
Advanced Technology and Features
The transformer weighs 225 tonnes. It operates as a single-phase, auto-coupled unit. It also includes an on-load tap-changing system.
A three-stage cooling mechanism supports stable performance. The system achieves the highest step-voltage and a wide tap range for its class.
Boost to Power Transmission System
The installation fills a key gap in Pakistan’s 765 kV extra-high voltage network. It also marks progress toward operating the country’s first substation at this level.
Officials say the project will improve grid stability. It will also help reduce regional power shortages once operational.
Future Expansion Plans
The next phase of the project will add six more main transformers. This step will further strengthen the transmission system.
The project forms part of Pakistan’s broader plan to modernize its energy infrastructure. It also aims to improve efficiency and reliability.
Long-Term Impact
Once completed, the Mansehra substation will support stable electricity supply. It will also contribute to long-term economic growth.
The project highlights growing cooperation between Pakistan and China in the energy sector.
