Ang 10kV (Tres Circuitos) Normal Pressure Sealed Air-Insulated Switchgear / Ring Main Unit mao ang high-performance medium-voltage power distribution solution nga gine-engineer aron suportahan ang tres independente nga power supply loops. Operasyon sa rated voltage nga 10kV, adunay normal-pressure sealed enclosure nga gigamit ang hangin isip primary insulating medium—eliminating ang panginahanglan sa SF₆ gas o pressurized systems. Kini nga switchgear nag-integrate sa switching, protection, ug control functions, makabag-o kini para sa mga scenario nga nagkinahanglan og robust multi-loop power distribution sama sa industrial complexes, urban substations, commercial hubs, ug critical infrastructure nga nanginahanglan og redundant power supply.
