Na 10kV (Tatu Circuits) Normal Pressure Sealed Air-Insulated Switchgear / Ring Main Unit shine high-performance medium-voltage power distribution solution engineered to support tatu independent power supply loops. Operating at a rated voltage of 10kV, it features a normal-pressure sealed enclosure that uses air as the primary insulating medium—eliminating the need for SF₆ gas or pressurized systems. This switchgear integrates switching, protection, and control functions, making it ideal for scenarios demanding robust multi-loop power distribution, such as industrial complexes, urban substations, commercial hubs, and critical infrastructure requiring redundant power supply.
