Abstract
The invention relates to a surge arrester comprising two opposing end fittings 3, one or more varistors 5 arranged between the end fittings 3, a winding layer 9 provided at least on the at least one varistor 5, wherein the winding layer 9 is a closed layer 9, and a reinforcement element 7 which extends between the end fittings 3 and keeps the end fittings 3 under tension, wherein the reinforcement element 7 is an open cross winding 13. Moreover, the invention relates to a method for producing this surge arrester.

2 more elements
Method for producing a surge arrester, including the steps of:
- providing a stack with two opposing end fittings and at least one varistor arranged therebetween;
- wrapping the stack with a resin-impregnated fibreglass thread to form an at least partly closed winding layer;
- and
- partially axially wrapping the stack to form an open cross winding by way of the relative rotation of the stack with a simultaneous back and forth movement in the longitudinal direction while the resin-impregnated fibreglass thread is supplied.
