Abstract
A gas cooled lightning arrester includes a plurality of zinc oxide blocks which are joined together to form serially connected non-linear resistors and capacitors. The blocks may be joined by clamps or metal plates may be bonded to the ends of the blocks. Cooling fins integral with the zinc oxide blocks or provided by the metal plates facilitate heat dissipation. The housing for the lightning arrester includes an inner wall which defines a channel for the convection flow of gas coolant.
