Ang 10kV (Tatlong Circuit) Normal Pressure Sealed Air-Insulated Switchgear / Ring Main Unit ay isang high-performance medium-voltage power distribution solution na inihanda upang suportahan ang tatlong independenteng power supply loops. Nag-ooperate ito sa rated voltage ng 10kV, at may normal-pressure sealed enclosure na gumagamit ng hangin bilang pangunahing insulating medium—na nagpapawala ng pangangailangan para sa SF₆ gas o pressurized systems. Ang switchgear na ito ay naglalaman ng switching, protection, at control functions, kaya ito ay ideal para sa mga scenario na nangangailangan ng robust multi-loop power distribution, tulad ng industrial complexes, urban substations, commercial hubs, at critical infrastructure na nangangailangan ng redundant power supply.
