Abstract
An insulator member comprises a porcelain insulator head and a polymeric shed secured to the insulator head. The insulator member can be used, for example, in an improved electrical line insulator which comprises a) an insulator unit comprising a porcelain head, and a polymeric shed secured to the porcelain head; b) a metal cap and a metal pin each situated at a surface of the insulator unit opposite to the other, the porcelain head forming a recess to receive the pin; c) cement mechanically securing the cap to the insulator unit; and d) cement within the recess and about the pin mechanically securing the pin within the recess. Methods of manufacture are also disclosed.
Claims36
A cap and pin insulator member comprising a porcelain head and at least one polymeric shed secured to the porcelain head, each such shed being composed entirely of an insulating polymeric compound.
A method of manufacturing a insulator member comprising
- a) providing a porcelain head, and
- b) securing at least one polymeric shed to the porcelain head, each such shed being composed substantially entirely of an insulating polymeric compound.
An electrical line insulator comprising
- a) an insulator unit comprising a porcelain head and at least one polymeric shed secured to the porcelain head, each such shed being composed entirely of an insulating polymeric compound;
- p1 b) a metal cap and a metal pin each situated at a surface of the insulator unit opposite to the other, the porcelain head forming a recess to receive the pin;
- c) securing means mechanically securing the cap to the insulator unit;
- and
- d) pin insertion means within the recess and about the pin mechanically securing the pin within the recess.
A method of manufacturing an electrical line insulator comprising
- a) securing a metal cap to a porcelain-polymer hybrid insulator, and
- b) securing a metal pin within a recess of the porcelain-polymer hybrid insulator,
- wherein said porcelain-polymer hybrid insulator comprises a porcelain head and at least one polymeric shed secured to the porcelain head, each such shed being composed entirely of an insulating polymeric compound.
