An elastomeric surge arrester housing includes a sleeve having a tubular core and radiating sheds. The sleeve is molded in a first configuration and, when the core is radially stretched, assumes a second configuration in which the sheds assume a downwardly extending configuration. The sheds, in the second configuration, include an upper surface having a generally frustoconical shape. The housing may be made using conventional molding techniques, but requires substantially less material than if the housing were molded directly into the second configuration.

An encapsulation (10) for an interrupter includes a main body that includes an internal cavity (14), the internal cavity (14) including a space at a first end thereof for the interrupter (12), a second end of the main body including a surface for mounting the encapsulation (10), an insert assembly (28) mounted in the second end for facilitating mounting the encapsulation (10), the insert assembly including a rigid connector (30, 32) and a plurality of fasteners (26) fixed to the rigid connector (30, 32).
摘要:
A transformer is disclosed, including a tank housing a transformer core/coil assembly, a dielectric insulating fluid surrounding said core/coil assembly, said fluid comprising a vegetable oil, an antioxidant dissolved in said oil, and a low temperature additive blended into said oil, said fluid defining a headspace above said fluid. The preferred embodiment includes an oxygen absorbing material contained in said tank and in contact with gases in said tank but isolated from contact with said dielectric fluid, said tank including an opening and a sealed plug in said opening, such that said oxygen absorbing material can be replaced through said opening upon removal of said sealed plug, and further includes a gas permeable polymer container sealed against said opening for supporting said oxygen absorbing material and an indicator in gas contact with said headspace and visible from outside the tank for indicating the presence of oxygen in said headspace.
摘要:
A windshield wiper blade (10) connector may be used in connecting a windshield wiper blade to pin-type and hookslot wiper arms. The connector includes two side walls (20) that defines a hole (95) sized to receive a pin of a pin-type wiper arm. A movable beam (60) is positioned relative to the hole (95) in the side walls so that the beam (60) engages the pin of the pin-type wiper arm when the pin is received in the hole to secure the connector to the pin-type wiper arm. A tab (70) extends from the movable beam (60) and is positioned so that the tab engages a slot of a hookslot wiper arm when the hookslot wiper arm is attached to the connector to secure the connector to the hookslot wiper arm.
