Abstract

A transformer bushing (3) and cooperating surge arrestor are provided wherein an insulating body (6, 44) has a foot (2) for securing the bushing to a transformer housing (1 ) and an input conductor (5, 35, 43) passing generally axially through at least a major part of the length of the insulating body. The input conductor terminates in an internal output terminal (8) at its operatively inner end and is electrically connected, in its operative condition, to an external input terminal (7, 34, 46) at or towards the operatively outer end of the transformer bushing remote from the foot. The external input terminal has a laterally extending conductor (9) electrically connected to it and having at its end region remote from the bushing a releasable terminal assembly (10) for cooperation with a coope.rant releasable contact (11 ) at one end of a surge arrestor (4, 32). The foot (2) has a bracket (12) with a terminal assembly (14) for operative association with a contact (15) at the grounded end of a surge arrestor such that, when the surge arrestor fails, it drops out of the operative position to a hanging inoperative position.
