Abstract
A generally disc-shaped polymeric insulating article (14) is in two parts to fit around the core (4) of an insulator (2). A first part (22) of the article (14) is substantially C-shaped to fit around the insulator core (4), and the second part comprises an insert (30) that slidably engages the first part (22) so as to secure the article in place. The article (14) projects a substantial distance radially from the insulator (2) to prevent animals and the like, bridging the length of, and thus electrically short circuiting, the insulator (2).
Claims12
A substantially planar electrically insulating article for protecting from being short-circuited electrical equipment that is of generally elongate configuration and that, in operation, has two longitudinally spaced apart portions at significantly different electrical potentials, the article comprising:
- a first part that is substantially planar and of generally C-shape, the first part having an aperture located substantially centrally thereof for receiving the electrical equipment therethrough, which aperture is elongated so as to form a slot that extends substantially unidirectionally to the perimeter of the first part;
- and
- a second part that forms an insert arranged to engage with the slot of the first part so as to complete the perimeter of the article and so as, in operation, to mount the article securely around the electrical equipment.
