A metal enclosed gas insulated switchgear is a common outdoor/Indoor electrical apparatus. The commonly used metal enclosed gas insulated switchgears include high voltage switchgear, tram switchgear and hybrid switchgear. Gas insulated switchgear is called GIS for short.
ZFW41-126/145 Outdoor/Indoor High Voltage Gas Insulated Switchgear
Our metal enclosed gas insulated switchgear ZFW41-126/145 is a mini gas insulated switchgear. It is jointly developed by our company and VEI-Longyuan Research Institute after they jointly introduced the technology of V. I. Lenin All-Russian Electro Technical Institute. It is an improved new high-tech product on the basis of digestion and absorption of Russian GIS/GCB advanced technology. This gas insulated switchgear is manufactured in accordance with the standards of IEC 62271-1-2007 and GB/T11022.
