Abstract
A lightning arrester comprises a plurality of column blocks disposed in parallel each of which has groups of a number of stacked nonlinear resistance elements and spacers interposed between the element groups, in which the element groups of the blocks are electrically connected in series by jumper conductors so as to form a series resistance and the spacers are formed of nonlinear resistance elements which can absorb energy, so that the arrester, as a whole, can absorb a larger amount of energy.
