During the critical period of China's 15th Five-Year Plan (2026–2030) power grid development, every newly built substation plays an essential role in ensuring regional energy security and grid stability.

Recently, Sansion Power successfully launched an on-site testing project for a 110kV substation, providing professional testing services for two main transformer bushings and transformer high-voltage riser CT (Current Transformer).

Facing the challenges of Xinjiang’s complex geographical environment, long-distance transportation, and demanding construction conditions, the Sansion Power technical team overcame multiple difficulties and delivered accurate test data and reliable technical support, helping customers achieve safer, more efficient, and higher-quality substation commissioning.

The project is a modular intelligent 110kV substation designed with an unmanned operation concept.

The entire station adopts a highly integrated design, with only one secondary equipment room, representing an important step in the modernization and intelligent development of the Xinjiang power grid.

Through professional testing and commissioning support, Sansion Power helped ensure:

• Reliable operation of transformer primary equipment
• Accurate performance verification of bushings and CT systems
• Improved safety and efficiency during substation commissioning

For this 110kV substation project, Sansion Power conducted key high-voltage testing tasks, including:

1. Transformer Bushing Testing

   Comprehensive inspection of transformer bushings to verify insulation performance, electrical reliability, and safe operation under high-voltage conditions.

2. Riser CT (Current Transformer) Testing

   Accurate testing of CT performance parameters to ensure measurement accuracy, protection system reliability, and stable operation of the power system.

With advanced testing equipment and experienced engineers, Sansion Power provided customers with precise test results and professional technical solutions.

From the Tianfu South 1000kV UHV Substation Project to high-voltage projects in Xinjiang, Sansion Power continues to build trust through professional expertise and engineering capabilities.

• Extensive Project Experience
• Professional Technical Team
• Reliable Quality Assurance

Moving Forward: Supporting More Power Grid Projects Worldwide

The successful completion of this stage marks another milestone in Sansion Power’s high-voltage testing services.

The technical team will continue participating in subsequent commissioning and construction work in Xinjiang, delivering professional solutions with advanced technology, strict standards, and reliable service.

With expertise in high voltage testing, transformer testing, substation commissioning, and power equipment diagnostics, Sansion Power is committed to contributing to the development of safer and smarter power grids worldwide.
