Product Overview

QMG-12 SF6 gas-insulated ring main unit features fully enclosed, maintenance-free, compact size, excellent performance, and high reliability, making it highly popular among users. The ring main unit has evolved from the initial air-insulated ring main unit to a compact SF6 gas-insulated unit and recently has advanced to an expandable SF6 fully insulated ring main unit or multi-circuit distribution cabinet. This development has led to significant progress in SF6 fully insulated switch technology. The application of various technologies, such as computer technology, electronic technology, sensor technology, and fiber-optic communication technology, in ring main units and multi-circuit distribution cabinets has further enhanced the product's miniaturization and intelligence.
