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 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 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.

摘要： An end fitting with stress distribution for supporting an end of a device, such as an insulator, placed tension. The end fitting has a mounting hole for receiving a cylindrical mounting pin therethrough. The mounting hole has a pair of contacting points spaced laterally relative to the vector line of force to redirect the tensile load applied to the end fitting by a mounting pin located in the mounting hole. The end fitting is especially useful in insulators subjected to tensile loads.

摘要： An end fitting with optimized weight for supporting an end of a device, such as an insulator, placed under tension. The end fitting has a mounting sleeve for coupling the end fitting to a core member, a mounting hole for receiving a cylindrical mounting pin therethrough and a cutout or removed portion positioned between the mounting hole and the mounting sleeve for optimizing the weight of the end fitting. The mounting hole can optionally be provided with a pair of contacting points spaced laterally relative to the vector line of force to redirect the tensile load applied to the end fitting by a mounting pin located in the mounting hole. The end fitting is especially useful in insulators subjected to tensile loads.
