ABSTRACT:
A stack of nonlinear resistors of sintered zinc oxide superposing one another is connected across a bottom of a grounded cylindrical housing and a high voltage conductor insulatingly supported by the housing. Within the housing a shielding conductor slantingly hangs from the connection of the stack and conductor. Alternatively, the shielding electrode may extend from the high voltage conductor to run along the longitudinal axis of the housing. A plurality of nonlinear resistors are divided in several stacks and serially interconnected between the shielding conductor and the inside of the housing to be radially outward inclined to the shielding electrode. Such stacks may be disposed close to the free end portion of the shielding electrode.
