Abstract
A new elbow canister fuseholder is provided that includes an electrically insulated and shielded housing for placing a fuse in-line between a cable and an electrical apparatus for underground distribution application. An insulating tube is contained within the housing for easy sliding removal of the fuse through an end plug such that the elbow is reusable when a fuse is replaced.
Claims17
An elbow fuseholder, comprising:
- a housing including a generally elongate insulative sleeve defining at one end thereof a cable entrance for receipt of a cable therein and at the opposing end a fuse entrance opening;
- an elbow interface joined to said sleeve at an angle and defining a mating interface for electrical connection with an external bushing insert;
- a fuse electrically connected at one end to a conductor of said cable received in said sleeve and electrically connected at another end to said elbow mating interface;
- an insulating tube disposed interiorly of said insulative sleeve, said fuse being slidably supported interiorly therein, said tube being elongate and of length to extend substantially from the cable conductor connection to the elbow interface;
- and
- a plug removably supported by said insulative sleeve at said fuse entrance opening and affixed to said fuse adjacent said elbow mating interface, said plug and said fuse being jointly removable from said sleeve through said fuse opening upon removal of said plug from said sleeve.
