2024年11月1日 · Gas-insulated switchgear (GIS) is a piece of high voltage equipment that is being constantly developed day by day. The basics of GIS technology is more or less the same, but everything else under the hood is improved a lot comparing to just a few years ago. This article explains major GIS components and their characteristics.

Siemens Energy has been awarded the contract to deliver ten bays of Blue gas-insulated switchgear (GIS) to Fingrid, Finland’s transmission system operator. It will be the first GIS in Finland that replaces F-gases with clean air, a pure mixture of nitrogen and oxygen with zero potential for global warming.

Gas-insulated high-voltage switchgear (GIS) is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces.

Protect your transmission and distribution facilities worldwide with MEPPI's Gas Insulated Switchgear (GIS). Learn more about our compact, leak-free enclosure solution.

HICO America's GIS units feature a remarkably compact design, perfect for installations where space is tight. Our 245 kV and below series typically use a three-phase common-enclosure design, while higher voltage units employ an isolated design for optimal performance.

2016年2月8日 · zA GIS is the implementation, within a complete HV substation, of the remarkable sulphur hexafluoride (SF6) properties in terms of voltage withstand and current interruption

2023年6月18日 · Gas-insulated switchgear (GIS) is a type of electrical equipment that uses a gas, such as sulfur hexafluoride (SF6), to insulate and protect various components of a power system. It consists of metal-enclosed compartments that house circuit breakers, disconnectors, bus bars, transformers, earth switches, surge arresters, and other devices.

GE Vernova provides GIS solutions from 50 kV to 800 kV, along with secondary products to maximize switchgear and network operation. The portfolio includes a full range of SF6 GIS as well as g3 (SF6-free) GIS at 145 kV and 420 kV voltage levels for utilities and industries worldwide.

At HICO America, we offer an extensive selection of Gas Insulated Switchgear (GIS) products designed to meet diverse operational requirements. Our GIS solutions range from 13.8kV up to 800kV, covering both medium-voltage (MV) and high-voltage (HV) applications.

Gas insulated switchgear with solid dielectric busbar for applications up to 2000A at 38kV Customizable, standards compliant (UL listed to IEEE C37.20.9) CBGS-0 includes main (SF6 insulated) and MV cable compartments, LV cabinet, and a (factory-sealed) shielded bus design for reduced risk.
