Vacuum circuit breaker WB series

medium-voltagefor nuclear applicationshigh-performance

Introduction of item Vacuum Circuit Breaker is a result of an optimal vacuum technology and structural design integrated with technologies accumulated while manufacturing vacuum interrupters for the first time in Korea, improving the breaking performance and stability. It is a premium product with a safer, more stable operation based on the user-centered design and its insulation improved with collective barriers and solid insulation by molding the vacuum interrupter. It stably supplied power to all industrial sectors including the power plants, chemical/steel plants and construction facilities. It is a new-conceptual circuit breaker with short arc time and interruption time due to short-circuits and ground failure, which aims for no maintenance. Product Features 1) It provides a product with an integrated technology, qualified atomic energy and various voltage ranges. - It is a product incorporated with an accumulated vacuum technology, operating device design and insulation design. - It is developed conforming to IEC international standards as well as IEEE(ANSI). - It is a product that can be used at various voltage settings including 7.2kV, 17.5kV, 24/25.8kV, 4.76kV, 8.25kV, 12/15kV, 27kV and 36/38kV. 2) It ensures the stability by self-manufacturing the vacuum interrupters. - We are manufacturing the vacuum interrupters for the first time in Korea, accumulating the technologies on vacuum and vacuum applications. - We provide the optimal arc extinguishing medium with high-vacuum, high arc extinguishing capability. - Based on our product quality and technology, we deliver our goods to many global firms including GE.
