380kV Power Transformers
Extra High-Voltage Transmission Infrastructure
High-capacity three-phase transformers engineered for 380kV transmission networks and grid interconnection applications. Our 380kV transformer solutions serve transmission substations, power generation facilities, and cross-border interconnection points, delivering reliable voltage transformation for critical grid infrastructure across central Europe.
Transmission Substations
Network transformers for 380kV/110kV voltage transformation in regional and national transmission infrastructure. Designed for high power capacity with advanced monitoring and protection systems for continuous grid stability.
Power Generation
Generator step-up transformers connecting power plants to 380kV transmission networks. Engineered for thermal power stations, combined-cycle facilities, and large-scale renewable generation with demanding overload requirements.
Grid Interconnection
Phase-shifting and interconnection transformers for power flow management between national grids. Critical components for DACH region cross-border electricity markets and grid balancing operations.
KAD manages complete 380kV transformer projects from specification through commissioning, working directly with transmission 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 oversized loads, crane coordination, and assembly supervision for multi-component transformer systems.
Installation oversight covers foundation verification, positioning accuracy, bushing assembly, cooling system integration, and protection equipment coordination. Commissioning protocols follow rigorous testing sequences including insulation verification, partial discharge testing, frequency response analysis, and load testing under operational conditions. All procedures follow IEC 60076 series standards and transmission operator specifications.
Long-term operational support includes condition monitoring systems, dissolved gas analysis programs, and predictive maintenance planning. Service agreements provide regular inspection schedules, oil processing services, and emergency response protocols. Technical documentation integrates with operator asset management systems for lifecycle tracking and regulatory reporting requirements.
