Abstract: A mounting bracket for mounting a high voltage surge arrester to a power distribution system including a main body with a first end securable to the high voltage surge arrester and an opposite second end securable to a power distribution system bracket and a plurality of laterally extending weathersheds located between the first and second ends, the second end including a fastening hole that receives a fastener for attaching the second end to the power distribution system bracket, and the main body being formed of polymer plastic blend.

Abstract: An arrester includes a dielectric housing that has a body portion that includes a substantially cylindrical wall with opposing first and second ends that form inner cavity therebetween. A support mounting bracket portion is formed as a unitary, one-piece extension of the body portion and extends laterally from said second end. The housing has sufficient rigidity to maintain the bracket portion in a position substantially perpendicular to the body portion. At least one varistor element is received in the inner cavity of the housing.

Abstract: An assembly is provided having a core and a housing. The housing has an internal passageway extending from a first housing end to a second housing end for receiving the core. A coating of an uncured moisture activated material is disposed between the housing and the core. The coating cures upon reacting with moisture penetrating the housing to reseal the housing at a point of moisture penetration. The material cross-links in the presence of the moisture, thereby bonding with the moisture to prevent the moisture from contacting the core. The cured material is a rubber-like substance that adheres to the housing and to the core, thereby resealing the housing at the point of moisture penetration.

Abstract: An insulator in the form of suspension insulator or pin type insulator has an elongated load sustaining body with a plurality of weathersheds extending radially relative to the longitudinal axis of the body on the outer surface of the body. The body and weathersheds are unitarily formed as one piece of rigid dielectric plastic polymer which are molded together. Clevis and eye coupling means are provided on the ends of the body to facilitate connection to support structures and high voltage lines.

Abstract: 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.
