ADB Double Break Disconnect
MindCore Technologies ADB is a station class double break switch, designed to utilize the high strength and lightweight characteristics of aluminum alloys, combined with time-tested silver brazed copper contacts that are highly visible and easily replaceable. The center stack supports the blade and rotates to operate the switch. The blade swings through 65˚, either clockwise or counter-clockwise in a plane parallel to the switch base.
Aluminum conducting joints are protected with an oxide inhibitor to prevent the formation of aluminum oxide. Copper contacts are tinned at attach point to aluminum surfaces to prevent galvanic corrosion and are further protected by an inhibitor on the aluminum surfaces. The ADB switch is a proven design and has been installed within the North American substations for the past 35 years.
