Abstract
A load separable connection is provided, including a loadbreak elbow having a contact probe, and a bushing into which the contact probe is received in a tulip contact therein. An ablative insert, including a projecting lip extending over the outer circumference of the tulip contact at the end thereof, is provided within bushing. The insert helps extinguish arcs created during live connection of the elbow over the bushing, and also helps physically block the access of the arc to the bushing components surrounding the tulip contact.

A bushing for a high voltage connector, comprising;
- a housing;
- a substantially non-conducting tubular contact tube disposed within said housing and having an interior surface;
- a contact disposed in said contact tube and having at least one radially outwardly actuable contact finger, said finger being disposed radially inward from said interior surface of said contact tube;
- an arc sensitive insert portion disposed adjacent said contact finger and disposed between said contact and said contact tube.
A high voltage connection, comprising:
- an elbow connector having a probe therein;
- a bushing having a bore therein for receiving said probe;
- a contact disposed in said bore, said contact being sized to engage said probe upon insertion of said probe into said bore, said contact including an actuable portion which moves upon engagement of said probe therewith;
- said bore having a size sufficiently greater than the size of said contact to permit free movement of said actuable portion, said bore and said actuable portion defining a gap therebetween;
- an arc-sensitive insert disposed in said gap.
