Compact and Integrated AIS Voltage Transformer Solution: Overcoming Space Constraints, Empowering Retrofit of Legacy Sites
During the upgrade and renovation of power supply systems in urban cores and rail transit, legacy substations often face the critical bottleneck of cramped space. Especially for Air-Insulated Switchgear (AIS), the dispersed arrangement of traditional Voltage Transformers (VTs) and their associated equipment (surge arresters, disconnectors) severely consumes valuable space, becoming a "bottleneck constraint" hindering retrofits and upgrades. To address this, we introduce the Compact and Integrate
