Abstract
A surge arrester includes a stack of components having at least one varistor. Each component has end faces, at least one of which is mechanically bonded to an end face of another component such that the combined components of the stack define a single, monolithic structure that serves as both an electrically-active element and a mechanical support element of the surge arrester. The surge arrester also includes an insulative housing surrounding the stack of components. The stack of components is capable of withstanding current pulses having magnitudes of 65 kA and durations of 4/10 microseconds without significant degradation in operating performance of the stack of components.
