A strut insulator for an overhead rail contact system includes a first end fitting, the first end fitting defining an inner side pocket, and a second end fitting spaced from the first end fitting, the second end fitting defining an inner side pocket. The strut insulator further includes a rod extending between the first end fitting and the second end fitting and extending into the inner side pockets of the first and second end fittings, the rod defining a length. The strut insulator further includes a shell surrounding a portion of rod, the shell extending along a portion of the length of the rod, the shell formed from a fluoropolymer.

A shed housing is disclosed. The shed housing covers an insulator including at least one shed. The shed housing includes a receiving cavity allowing an upper surface and a lower surface of the shed to be received in the receiving cavity. The shed housing is provided with a mounting hole through which the insulator passes, and an opening corresponding to the mounting hole. The opening communicates the mounting hole with an outer edge of the shed housing. The mounting hole communicates with the receiving cavity. A first connecting portion and a second connecting portion cooperating with the first connecting portion are arranged respectively on both ends of the opening. When the first connecting portion is connected to the second connecting portion, the shed housing is closed along a circumferential direction. The shed housing is able to receive the entire piece of shed, and can be assembled on the shed without any additional connecting components, which is convenient and high-efficient and has good effect on preventing pollution flashover and rain flashover.

A gap sub assembly for electromagnetic telemetry used in downhole drilling is disclosed. The gap sub comprises a female part comprising a female mating section and a male part comprising a male mating section. The male mating section is matingly received within the female mating section and electrically isolated therefrom. One or more electrically insulating bodies secure the male part axially and torsionally relative to the female part. The electrically insulating bodies also electrically isolate the male part from the female part. The electrically insulating bodies can be installed through apertures in the female part or at least some of the electrically insulating bodies can be installed before the male mating section is inserted into the female mating section. The electrically insulating bodies can be held in place on the male mating section using a retention apparatus such as a ring, a scarf, pods or an adhesive.

An apparatus configured to prevent electrical outages is provided herein. Methods of coating a transformer in an insulator coating are also provided herein. In various exemplary embodiments. the apparatus comprises an insulator configured to prevent an electrically charged animal or debris from contacting a grounded surface of a transformer.

A water proofing protecting cap that is placed over a terminal consolidation splice portion of a wire harness. The protecting cap being a dip molded transparent tubular body that is provided with a bottom portion wherein, from an opening for insertion at the other end, the protecting cap can be filled with a water sealant and a terminal consolidation splice portion of a wire harness is insertable. A marking line made by a rib on a male mold used in the dip molding is provided in a circumferential direction on an inner circumferential surface of a peripheral wall and is distanced by a required height from an inner surface of the bottom portion toward the opening, and a non-transparent line is provided on an outer circumferential surface of the peripheral wall following the marking line.
