An electrical feed-through apparatus is prevents or substantially reduces partial corona discharges in penetrators for high voltage supply for underwater facilities. A flange of a first thickness has an opening providing a passage between first and second oppositely located sides of the flange. An elongated tube of a solid, electrically insulating material has a first length greater than the first thickness, and is positioned in the passage, with first and second parts of the tube protruding from the first and second sides of the flange, respectively. First and second attachment sleeves are positioned on the tube and are attached to the first and second parts of the tube, respectively, at a distance from respective first and second ends of the tube. The sleeves are attached to the respective first and second oppositely located sides of the flange.

An illustrated view of an exemplary stinger holder for preventing electric arcing from harming equipment, property and people is presented. The stinger holder is useful for keeping people and objects out of harm's way when by preventing kick around and letting an arc couple to the equipment and ruin the equipment, people and other property. Also, the stinger holder is useful for grinder equipment by holding pipes from falling into water at a bottom of a ditch. The stinger holder prevent electrical DC shock and thereby providing longevity to the equipment and provide a guard for the people.

An insulator system includes an insulator assembly including: a first insulator; a second insulator; a first end fitting at a first end portion of the first insulator; a second end fitting at a second end portion of the first insulator; a third end fitting at a first end portion of the second insulator and operatively coupled to the second end fitting; a fourth end fitting at a second end portion of the second insulator; a first cement layer between the first insulator and the first end fitting; a second cement layer between the first insulator and the second end fitting; a third cement layer between the second insulator and the third end fitting; and a fourth cement layer between the second insulator and the fourth end fitting. An electrically insulating layer is on the first cement layer and extends between the first insulator and the first end fitting.

For protecting wildlife from high voltage conductors, dielectric covers are used to cover fuse cutouts, bushings, solid-blade disconnects, lightning arrestors, or other high voltage components. To increase a vertical surface distance between the top of the cover and the bottom of the cover, a plurality of protruding skirts are molded into the cover. The cover is formed of two molded halves, which are later affixed together. To prevent water entering the junction between the two halves, one half is formed with a lip that overlaps the edge of the other half. Retaining pins secure the cover in place.

A hollow insulator for high electric voltages has an insulating tube and a covering of the insulating tube made from a fiber-reinforced plastic. The covering is placed on an outer surface of the insulating tube. There is also described a method for producing the type of hollow insulator.
