1. A method of producing a surge arrestor module, comprising:
providing a plurality of MOV blocks arranged in a stack;
wrapping a tape to surround the stack;
surrounding the stack with an epoxy-fiberglass layer;
placing the stack with the applied epoxy-fiberglass layer into a flexible bladder, the flexible bladder being located in an outer tube structure; and
while the epoxy-fiberglass layer is curing around the outer surface of the stack, applying pressure to the flexible bladder to generate a compressive force to the epoxy-fiberglass layer and the stack.
