Abstract: Loadbreak connectors which are modified to reduce the probability of flashover upon disassembly operation of a loadbreak bushing insert from a power cable elbow connector. The bushing insert is provided with vents to vent a cavity formed between the elbow cuff and the transition shoulder portion of the bushing insert with ambient air to avoid a decrease in pressure within the connection region and avoid a decrease in the dielectric strength of the air therein thus preventing flashover. The vents can be provided directly on the transition shoulder portion of the insert, an elbow seating indicator band or on a bushing insert interface shell. Additionally, the band and the shell may be formed of a bright contrasting color which serves to indicate whether the loadbreak connector is improperly assembled. The shell further reduces friction upon assembly of the connector.

Abstract: To control the direction of movement and prevent random scattering of fragments of MOV blocks resulting from the catastrophic failure of such blocks during overvoltage incidents, a stack of such MOV blocks with end fittings attached is placed within a rigid filament-wound epoxy-impregnated tube formed as one continuous tube or a tube made up of aligned tube segments positioned so as to establish a preferred failure direction; the interstices between the interior of such tube and the exterior of said blocks and end fittings are filled with a dielectric insulative material which extends beyond and engulfs said tube and said end fittings to seal and further rigidify said component stack and provide an air-free non-electrically ionizable environment about said component stack.

Abstract: This invention is directed to electrical connectors for joining components of high voltage electrical systems, such as splices and elbows for joining high voltage cables and high voltage cables to transformers and the like. Each connector has at least one extendable conductor to which a high voltage cable may be coupled outside of the housing and then returned to the protection of the housing. Typically the elbow has one while the splice has two extendable conductors. Removable fasteners may be used to hold the extendable conductors out of or adjacent the housing ends and lockable fasteners hold the completed joints within the housing.
