POWERCHINA completes installation of seven transformers at Pakistan’s highest-voltage substation

Mansehra: China’s POWERCHINA has successfully positioned all seven 765-kilovolt (kV) main transformers at its Mansehra Substation Project in Pakistan, marking a major milestone in the construction of the country’s highest-voltage substation.

The achievement signals a significant breakthrough in the development of Pakistan’s power transmission infrastructure, with the project now entering the comprehensive equipment installation phase.

Following the successful positioning of the first transformer on April 17, the project team has completed the positioning of all seven main transformers, each weighing 225 tonnes, marking substantial progress in the construction of the strategically important facility.

The massive transformers were transported to the project site in phases beginning in November 2025, with all seven units successfully delivered over a period of 344 days. Their transportation and positioning involved considerable logistical coordination and technical expertise to ensure the safe handling of the heavy electrical equipment.

To ensure the safe and efficient positioning of the transformers, POWERCHINA’s project team conducted multiple technical coordination sessions with supervision experts and completed the necessary reviews and approvals of technical documentation and testing plans.

The operation was undertaken through close coordination between Chinese technical specialists, who provided remote technical guidance, and Pakistani personnel, who carried out the work on site. The collaborative arrangement enabled real-time communication and coordination between the teams, ensuring the smooth execution of the complex operation.

Upon completion and commissioning, the Mansehra Substation is expected to play a crucial role in facilitating the integration and transmission of clean hydropower generated by the Dasu Hydropower Project, supporting Pakistan’s efforts to strengthen its electricity transmission network and expand the utilisation of renewable energy.

The substation is also expected to contribute to improving grid stability and enhancing the reliability of Pakistan’s power transmission system, helping accommodate additional electricity generated through major hydropower investments.

The latest development underscores POWERCHINA’s continued contribution to Pakistan’s energy infrastructure and highlights the growing cooperation between Pakistan and China in the development of modern power transmission facilities.

Through projects aimed at strengthening electricity generation and transmission capacity, Chinese enterprises continue to support Pakistan’s efforts to improve energy security, enhance grid performance and advance sustainable development.
