Abstract: Surge arrester with a module 1, 3, 9, 25, which comprises a stack of varistor blocks 1, two end armatures, between which the stack of varistor blocks 1 is held, a plurality of reinforcing elements 9, which extend between the end armatures 3 and are fixed to said end armatures, the reinforcing elements 9 surrounding the stack of varistor blocks, and at least one stabilizing disc 25, which is arranged between two varistor blocks 1 in the stack and guides the at least one reinforcing element 9, and with an outer housing 5 with screens, in which outer housing the module is at least partially accommodated. In the case of the surge arrester according to the invention, the outer housing is designed in such a way that the module is accommodated without any gas, liquid or volumes or cavities therebetween. Furthermore, each of the stabilizing discs 25 is arranged in the region of one of the screens 7.
