Abstract
A cover for application to a top surface and adjacent portion of the sidewall of a distribution transformer to prevent electrical shorting across the top surface and sidewall portion. The cover comprises an electrically non-conductive material which electrically insulates the transformer top surface and sidewall portion. An aperture is provided in the cover to accommodate a terminal of the transformer.
Claims14
A cover for application to a transformer, said cover comprising:
- a discoidal lid sized for covering a top surface of said transformer, said lid comprising an electrically non-conductive material and having at least one aperture sized and positioned for accommodating a terminal of the transformer;
- a plurality of ventilating openings in said lid;
- a skirt extending downwardly from the periphery of said lid;
- and
- means for securing said skirt to the transformer, whereby said transformer top surface is electrically insulated to prevent electrical shorting across the top surface.
