High voltage insulators are disclosed, along with related methods of manufacture and use. The disclosed high voltage insulators include a core strength member joined to one or more end fittings and secured with one or more elastomeric members. A plastic body surrounds the core strength member, the elastomeric member, and at least a portion of the end fitting. In particular, the plastic body is molded over the elastomeric member(s) and, upon cooling, the plastic body exerts a radial compressive force on the underlying elastomeric member(s) to seal the joint of the high voltage insulator and protect it from moisture, even throughout temperature fluctuations in the field.

An electrical insulator apparatus and method of manufacturing an electrical insulator apparatus includes a core strength member which is positioned at least partially within at least one end-fitting. A thermoplastic exterior body having a plurality of spaced fins is injection-molded over the core strength member and at least partially over the at least one end-fitting. The core strength member is attached to the at least one end-fitting without a mechanical compression to the at least one end-fitting and without an adhesive between the core strength member and the at least one end-fitting. One or more mechanical upset structures formed on the at least one end-fitting prevent movements of the injection molded thermoplastic exterior body relative to the at least one end-fitting.

A conductor cover apparatus for use with an overhead electrical transmission and distribution system and related methods is provided. The conductor cover apparatus has a center cover member. At least one arm connector is formed on the center cover member, the at least one arm connector having an opening and a first hole positioned between a first external side and a second external side of the at least one arm connector. An extension arm is positioned at least partially interior of the first and second external sides of the at least one arm connector. At least one pin is removably connecting the extension arm to the at least one arm connector, wherein the at least one pin is positioned through the first hole of the at least one arm connector and a first arm hole within the extension arm.

A new cross linked polyolefin material combination that is designed to replace current high-density polyethylene ('HDPE') materials for use with molded or over-molded electrical transmission products. Such molded or over-molded electrical transmission products include, for example, vise-top pin insulators, line post insulators, F-neck, C-neck, and J-neck pin insulators of classes ANSI 55-3, 55-4, and 55-5, Spacer cable spacers, Brackets, hangers, Line post sensors, cable restraint insulators, and transmission style insulators.

Cross-linked polyolefin material blend molded electrical transmission insulating products

A material combination that is designed to replace current high-density polyethylene ('HDPE') materials for use with electrical transmission comprising at least one low density, cross-linkable polymer resin, at least one high density polymer, a cross-linking catalyst and an optional color masterbatch The material combination provides all of the existing properties found in the HDPE material with the addition of a higher temperature capability at/above 250&#xb0; C.
