Natural disasters caused by extreme weather, including flooding, heat, and drought, continue to affect energy security and impact millions of people and businesses each year, costing billions. In response to these challenges and to meet customer demand for power safety and reliability, ABB has designed a next-generation extreme weather-resistant housing cabinet for its R-MAG magnetically actuated dead tank breaker for medium-voltage primary substations.
Available for 15-, 27-, and 38-kV units, the housing has been designed to the stringent NEMA 4 rating standards, offering unparalleled protection against even the most severe water and dust ingress. Featuring seamless roof-to-wall joints and external self-sealing bolts that prevent any gaps, the housing is completely secure and watertight. A new roof overhang also helps limit water exposure, plus the bushings-to-roof interface is secured by a superior aerospace-grade, UV-resistant, and more robust gasket.
