Abstract
An electrical module assembly used in a surge arrester is manufactured by wrapping an electrical module assembly including at least one metal oxide varistor (MOV) disk to which a reinforcing structure including a pre-impregnated epoxy/glass-fiber composite has been applied with shrink film and compacting the wrapped electrical module assembly by heating the shrink film such that the shrink film shrinks and applies a radially compressive force to the electrical module assembly. The wrapped electrical module assembly then is cured at a temperature at which the shrink film no longer applies a compressive force.
Claims22
A method for manufacturing an electrical module assembly, the method comprising:
- providing an electrical module assembly including at least one MOV disk to which a reinforcing structure has been applied;
- wrapping the electrical module assembly with shrink film;
- compacting the wrapped electrical module assembly by heating the shrink film such that the shrink film shrinks and applies a compressive force to the electrical module assembly;
- and
- curing reinforcing structure of the wrapped electrical module assembly at a temperature at which the shrink film no longer applies a compressive force.
