Abstract: The present invention relates to a transformer includes a housing, a bushing, a core-and-coil unit, an electrical connector, and a connecting rod. The bushing is located in an opening in the housing and comprises a conductive tube surrounded at least partially by an insulating layer. The electrical connector is coupled to the core-and-coil unit in the housing. The connecting rod extends through at least a portion of the conductive tube with one end of the rod being connected to the electrical connector. The connecting rod and the bushing can be moved with respect to each other to electrically couple the electrical connector the conductive tube.

Abstract: A mount for securing a load, for example a strut insulator, to a stationary support has a pair of end parts one of which is fixed to the load and the other of which is fixed to the support and a pair of respective intermediate parts. Respective end pivots connect the intermediate parts to the end parts for pivoting thereon about respective axes that are perpendicular to each other and a central pivot connects the intermediate parts to each other for relative pivoting about a center axis lying substantially perpendicular to the end axes. One of these end axes is at least generally horizontal and at least generally aligned with the load.

Abstract: A high voltage composite member, such as a support insulator or a bushing, comprises a core and a sheath of elastomeric material vulcanized to the core and at least one module of elastomeric material having an external shed and an inner cylindrical surface of predetermined normal diameter. The sheath has circumferentially continuous external bulges overlapping and engaging the ends of the inner surface to hold the module permanently in a desired location on the sheath, the module being substantially free of deforming stress. A sealing material provides a sealed interface between the module and sheath.
