The present disclosure relates to an improved service entrance head that allows for replacement of the service entrance head without requiring that the wiring/lines within the service head be severed.

The present disclosure describes grommets formed of a polymeric material and adapted for holding a plurality of discrete cables. A grommet may comprise two halves, each half comprising: a main body having a generally arced outer surface, a plurality of angled cantilevered tines integrally coupled to the main body and extending generally radially inward from the main body; and a slidable interconnection feature integral with the main body, wherein the slidable interconnection feature for each respective half is dimensioned to mate with the slidable interconnection feature of the other half, allowing the two halves to slide into an interlocking position with each other when compressed together

A cable-gland system provides a sealing function to openings in an electronic chassis that receive cables. The cable-gland system comprises a plurality of individual cable glands. Each of the plurality of individual cable glands includes an exterior end to be positioned adjacent an exterior of the chassis, and an interior end for positioning within the chassis. Each of the plurality of individual cable glands includes a through-hole extending between the exterior and interior ends for receiving one of the cables, and an outer surface between the exterior and interior ends. Each of the plurality of individual cable glands has a male projection on one side of the outer surface and a female recess on an opposing side of the outer surface. The cable glands are connectable to form the cable-gland system by mating the male projection on one cable gland with the female recess of an adjacent cable gland.

Disclosed are an insulated pipe and an insulated bushing. The insulated bushing (1000) includes: an insulator (110) including an intermediate shed member (112), and a lower flange (114) arranged on a lower end of the shed member; a head member (120) connected to an upper end of the insulator, wherein the head member includes an oil conservator (121) connected to the upper end of the insulator and a connecting terminal (122) connected to the oil conservator; and an insulated pipe (100) connected to the lower flange, wherein the insulated pipe includes a upper transformer pipe (101) and a lower oil-immersed pipe (102), and the transformer pipe includes an inner pipe (103), and a conductive layer arranged outside the inner pipe and configured to be grounded. The insulated pipe and the insulated bushing solve the problems of connection and sealing, and save material cost greatly.

The device and process disclosed relates to hot sticks suitable for working on high voltage conductors in high temperatures. The enhanced hot sticks include a thermal insulating piece between the pole and the end tool. The disclosed hot stick retains electrical and mechanical properties at least as good as those of regular hot sticks and can be used on high temperature lines in the same way as regular hot sticks are presently used to perform live work on normal lines.
