Gas Insulated Switchgear
Gas Insulated Switchgear
Adopting a three-phase common tank structure, the GIS is composed of modular standard components. This design facilitates high-quality production organization and installation, and meets the design and layout requirements of various substations.
The circuit breaker adopts the self-energy arc-extinguishing principle, providing high short-circuit breaking and closing capabilities.
The disconnector can meet the requirements of switching bus transfer current and bus charging current; the quick earthing switch can meet the requirements of closing short-circuit current and switching induced current.
The circuit breaker has a full-capacity electrical life of 22 operations and a mechanical life of 10,000 operations; the disconnector/earthing combination switch has a mechanical life of 10,000 operations and a partial discharge magnitude of only 3 pC, fully meeting user application requirements.
"There is always a ring main unit suitable for you!" Juhonkia continues to introduce new products in the field of ring main units. The ring main unit series products achieve full coverage of voltage levels and different insulation media products. It is the first domestic enterprise to simultaneously complete the R&D, manufacturing, network access testing and batch supply of standardized and customized SF6 gas insulation, solid insulation, environmentally friendly gas insulation, atmospheric air insulated ring main switchgear primary and secondary integrated ring main switchgear.
