China is the world's largest producer of high-voltage switches,the user requires more than 20 years for the effective life of the high-voltage switch.Grease has a very important influence on the safety, reliability, durability and environmental adaptability of medium and high voltage switch.Mainly reflected in operating mechanism lubrication, electrical contact lubrication, GIS sealing lubrication.
Since 2016, VNOVO has participated in the research and development of localized replacement of high-voltage switch grease together with China Xidian Group and Pinggao Electric, and successfully developed a variety of grease products.Through a variety of simulation tests, it meets of the different structures’ requirements of long-life lubrication, load resistance, anti-aging, material compatibility, low volatility, and low oil content.
