380kV
Power ­Transformers

380kV transformers operate at the extra-high-voltage level, serving as critical nodes in national and cross-border transmission networks. We manage complete 380kV transformer projects from specification through commissioning, working directly with transmission system operators and power generators. Our engineering teams coordinate complex logistics, site preparation, and specialized installation requirements for extra-high-voltage equipment. Project management includes transport planning for heavy-load transports, crane coordination, and assembly supervision for multi-component transformer systems.

380kV Overview -
Critical Nodes in Transmission Networks

  • 380kV primary side with various secondary configurations
  • ONAN/ONAF/OFAF with redundant systems
  • IEC 60076 series, EN 50588, HD 428
  • Up to 1000 MVA
  • Full type testing at accredited laboratories

These units transmit bulk power between generation sites and regional grids. We supply single-phase and three-phase configurations up to 1000MVA, equipped with on-load tap changers and designed for long-distance transmission stability. Transport logistics and heavy-load routing support included.

Application Areas:

  • Transmission network substations
  • Cross-border interconnection lines
  • Large-scale power plant grid connections
  • Grid stability and load balancing
  • Complex Project Execution. Comprehensive engineering support for extra-high-voltage transformer projects including transport logistics, site coordination, and specialized installation requirements for transmission infrastructure.
  • Quality Assurance. Factory acceptance testing, independent laboratory verification, and comprehensive documentation packages meeting transmission operator requirements and international standards.
  • Operational Support. Long-term maintenance programs, condition monitoring systems, and technical support throughout multi-decade operational lifecycles typical of transmission equipment.
