Copper Busbar Jointing Methods

Bolted JointsClamped JointsRiveted JointsSoldered Or Brazed JointsWelded JointsClamped joints are formed by overlapping the bars and applying an external clamp around the overlap. Since there are no bolt holes, the current flow is not disturbed resulting in lower joint resistance. The extra mass at the joint helps to reduce temperature excursions under cyclic loads. Well-designed clamps give an even contact pressure and are e...See more on electrical-engineering-portal Storm Power Components
