Abstract
A method and apparatus for protecting electrical power transmissions systems that may or may not be energized. A protector and method for protecting a component of an electrical power transmission system. A dielectric cover is molded to fit around the component. The dielectric cover has a peripheral edge including portions with cooperating mating surfaces that, in use, mate together to secure the dielectric cover on the component. A grip portion, for example the mating surfaces, of the dielectric cover is preferably shaped to receive a hot stick. The dielectric cover may be provided with ventilation openings, and a friction enhancing interior surface, such as a weak adhesive on an interior surface of the dielectric cover.
Claims27
A protector for a component of an electrical power transmission system, the protector comprising:
- a dielectric cover spray molded to fit around the component by spraying a mixed two part resin composition in multiple layers onto a mold using an applicator, the two part resin composition being formed from resin components that react and begin setting upon exit from the applicator and set sufficiently upon impact with the mold to allow a continuous build up of coating thickness during spray molding of the dielectric cover;
- and
- the dielectric cover having a peripheral edge including portions with surfaces that, in use, secure the dielectric cover on the component after removal of the dielectric cover from the mold.
A method of protecting a component of an electrical power transmission system from damage, the method comprising:
- placing a dielectric cover over the component, the dielectric cover having been spray molded to have a shape that fits around the component by spraying a mixed two part resin composition in multiple layers onto a mold using an applicator, the two part resin composition being formed from resin components that react and begin setting upon exit from the applicator and set sufficiently upon impact with the mold to allow a continuous build up of coating thickness during spray molding of the dielectric cover;
- and
- securing the dielectric cover on the component after removal of the dielectric cover from the mold.
A method of preparing a dielectric cover for protecting a component of an electrical power transmission system from damage, the method comprising:
- spray molding a mixed two part resin composition onto a mold to form a dielectric cover having a shape that fits around the component by spraying the mixed two part resin composition in multiple layers onto the mold using an applicator, the two part resin composition being formed from resin components that react and begin setting upon exit from the applicator and set sufficiently upon impact with the mold to allow a continuous build up of coating thickness during spray molding of the dielectric cover, the dielectric cover being adapted to be placed over and secured to the component after removal of the dielectric cover from the mold.
