Product descriptions from the supplier
Overview
The operating mechanism and the electrical part adopt a separated - compartment design. The main transmission mechanism and the high - voltage live parts are in mutually independent oil chambers.
Compact Structure: Small in size yet operates stably.
Occupies only 130mm under the transformer tank cover, yet ensures stable operation for 300,000 voltage regulation cycles.
Significantly reduces the transformer height. Without compromising performance, it cuts manufacturing costs and saves transformer oil.
Simplified structure: The fewest components ensure maximum reliability.
Strong Adaptability: High - quality, multi - mode product handles various harsh environments.
Stable operation within -25℃—60℃ and 100—260V voltage range.
Sudden power failure won’t affect switch gear - shifting operations, safer to use.
Three operation modes can be flexibly used to meet various special environments.
Vacuum arc extinction: Maintenance
free for more peace of mind. - The unique characteristics of vacuum arc extinction perfectly avoid contact burning and insulation oil carbonization.
Eliminate pollution from the source. It can ensure the cleanliness of the transformer oil without the need for an oil - filtering device, thus saving on such equipment.
Greatly reduce the daily maintenance workload during the use of the transformer.
The transformer oil can be used for a long time, achieving energy conservation and consumption reduction, and also saving maintenance costs during use.
Customized high - performance vacuum chambers with reliable performance.
