摘要： An insulator assembly for a polymeric cutout assembly has a core with first and second ends and an outer surface. First and second end caps are attached at the first and second core ends. The end caps have outer surfaces. A sleeve is disposed on the outer surface of the core. A projection extends laterally outwardly from an outer surface of the sleeve. An insulator is molded around the outer surface of the core, the sleeve and the first and second end caps. A center pin is attached to the projection to secure the cutout assembly to a support.

摘要： A disconnector assembly connects and then isolates and disconnects an arrestor between a power line and ground. The disconnector assembly has a bracket that has a base and a wall. The wall extends substantially perpendicularly from the base and defines a cavity. An isolator assembly is disposed within the cavity. A cap is connected to the wall remote from the base to close the cavity. A blind bore extends into the cap from a surface thereof remote from the cavity. A stud is partially disposed in the bore. An adhesive between the cap and the wall secures the cap to the wall.

摘要： A device for connecting, and then isolating and disconnecting an arrester includes a non-conductive housing with two electrical terminals. The housing has opposite ends separated by an internal chamber. The terminals are mounted at the housing ends. A resistor engages and extends between the terminals in the housing internal chamber. A cartridge with an explosive charge is mounted in the internal chamber adjacent the resistor. A gap spacer surrounds the cartridge, is adjacent one of the terminals and is spaced from the other terminal.

摘要： An electrical insulator in the form of a pintype insulator has a load sustaining mechanical core and a dielectric sheath overlying the mechanical core to protect the mechanical core from the weather. The mechanical core is constructed of a load sustaining dielectric material which is different from the dielectric material of the sheath. The mechanical core has a profiled outer surface with a top groove, two side grooves, an annular rib and an axially extending threaded bore. The dielectric sheath is applied over the mechanical core as thin as practical to minimize the amount of sheath material being used. However, the dielectrical sheath is molded on the mechanical core to form a pair of weathersheds which can either extend radially outwardly therefrom or substantially downwardly therefrom in the form of vertical sheds.

摘要： An electrical surge arrester includes an arrester block stack with a plurality of cylindrical surge arrester components arranged substantially coaxially to form a cylindrical stack of components having a longitudinal axis. First and second electrical conductive terminals are disposed at each end of the block stack and electrically coupled to the components. A spacer is disposed between each of the terminals and the plurality of cylindrical surge arrester components. A crimp pin is disposed in each of the metal terminals to plastically deform the terminals to compress the block stack. Rubber sheds can be directly molded around the device.

摘要： A disconnector assembly for an arrester includes a housing having first and second opposite ends. A cavity is disposed within the housing. A first electrical terminal is disposed at the first end of the housing, and a second electrical terminal is disposed at the second end of the housing. A cartridge with an explosive charge disposed in the cavity between the first and second electrical terminals. The cartridge has a powder load greater than 0 grams and not greater than approximately 0.15 grams. The powder load is sufficient to separate said second electrical terminal from said first electrical terminal upon cartridge detonation while minimizing the intensity of the explosive separation upon unintended cartridge detonation.

摘要： An electrical insulator for supporting an electrical conductor includes a load sustaining molded core, a mounting on the core, an dielectric sheath, and a metal cap. The molded core is formed of a dielectric polymer with opposite longitudinal ends and a profiled lateral outer surface between the ends. The dielectric outer sheath overlies the core outer surface and has a weathershed extending laterally outwardly relative to the core. A metal cap is secured to one end of the core by the metal cap having a portion directly molded to the core. The mounting is located on the end of the core opposite the metal cap.

摘要： An electrical connector, such as a bushing insert, includes a housing with an inner bore, opposite ends. One end has an opening providing access to the inner bore. A piston-contact element is movable between first and second axially spaced positions within the inner bore. During fault closure or short circuit conditions, the piston-contact element accelerates connection with a male contact of an electrical connector, such as a cable connector, thereby inhibiting the formation of flashover or electrical arc.
