The metal plates of EBW shunt resistors are manufactured by precision stamping dies. One typical model has one through-hole for mounting and three teeth for welding lead wires. The plates, which serve as semi-finished products, can be integrated with multi-strand wires in customers’ plants. The resistance value, rated power can be specified by customers from a wide range.
