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
An apparatus comprising:
- a disk assembly including at least a first MOV disk defining a first surface and a second MOV disk defining a second surface, the first surface in direct contact with the second surface;
- a reinforcing structure applied to at least a portion of one of the first MOV disk and the second MOV disk;
- and
- a removable film applied to the disk assembly and the reinforcing structure, the film being configured to compress the disk assembly.
An apparatus comprising:
- a disk assembly including at least a first MOV disk and a second MOV disk;
- a reinforcing structure applied to at least a portion of one of the first MOV disk and the second MOV disk;
- and
- a film applied to the disk assembly and the reinforcing structure, the film being configured to compress the disk assembly such that a portion of the first MOV disk and a portion of the second MOV disk are coupled directly together along an axial direction.
An apparatus comprising:
- a disk assembly including at least a first MOV disk defining a first surface and a second MOV disk defining a second surface, the first surface in direct contact with the second surface;
- a reinforcing structure applied to at least a portion of one of the first MOV disk and the second MOV disk;
- and
- a film applied to the disk assembly and the reinforcing structure, the film being configured to compress the disk assembly, wherein the film being configured to compress the assembly comprises the film being configured to shrink in response to being heated to a first temperature.
