Historical information

Insulates electrical wire/cable which is attached between narrow and wide ends of the 'bell' shape (in a groove). Screwed onto the cross arm of a power pole. Non conductive so electricity doesn't short out to the ground.

Significance

Used on power poles in the Kiewa Valley.

Physical description

White porcelain bell shaped insulator with an indent between the wide open end and the narrow closed end (for cable to be attached). The wide end is open with a white porcelain cylinder inside narrowing to thread for screwing in the narrow section.
