Abstract
A method produces a hollow electrical insulator. The method includes: winding first wound layers of a first fiber element onto a core; and winding second wound layers of a second fiber element onto an end region of the core. The first wound layers have turns of the first fiber element which enclose a first winding angle with a main direction of extension of the core. The second wound layers have turns of the second fiber element which enclose a second winding angle with the main direction of extension of the core which is larger than the first winding angle. An inner region of the core remains free of second wound layers.
