Abstract

An insulator support pin includes a strength member and a non-conductive sheath surrounding the strength member. The non-conductive sheath extends between a first end and a second end. The insulator support pin also includes a support member between the first end and the second end. The first end is configured to attach to an insulator, and the second end is configured to attach to a support structure.

Claims (52)

1 . An insulator support pin comprising:

a strength member;

a non-conductive sheath surrounding the strength member and extending between a first end and a second end, with the non-conductive sheath having a bore at the second end, with the first end of the non-conductive sheath encapsulating a respective segment of the strength member such that the strength member terminates within the bore so as to not extend beyond the first end of the non-conductive sheath; and

a support member between the first end and the second end, wherein:

the first end of the non-conductive sheath, with the respective segment of the strength member encapsulated therein, is configured to attach to an insulator, and the second end of the non-conductive sheath is configured to attach to a support structure.

2 . The insulator support pin of claim 1 , wherein the strength member is non-conductive.

3 . The insulator support pin of claim 1 , wherein the support member has a tapered sidewall.

4 . The insulator support pin of claim 1 , wherein:

at a first distance from the first end of the non-conductive sheath the support member has a first width,

at a second distance from the first end of the non-conductive sheath the support member has a second width,

the first distance is different than the second distance, and

the first width is different than the second width.

5 . The insulator support pin of claim 1 , wherein at least one of:

the first end of the non-conductive sheath is configured to threadingly attach to the insulator; or

the second end of the non-conductive sheath is configured to threadingly attach to the support structure.

6 . The insulator support pin of claim 1 , wherein:

at a first location between the first end and the second end, the non-conductive sheath has a first mating portion,

at a second location between the first end and the second end, the non-conductive sheath has a second mating portion,

the first mating portion and the second mating portion mate with one another to couple a first portion of the non-conductive sheath to a second portion of the non-conductive sheath,

the first portion of the non-conductive sheath extends between and includes the first end of the non-conductive sheath and the first mating portion,

the second portion of the non-conductive sheath extends between and includes the second end of the non-conductive sheath and the second mating portion, and

when the first mating portion and the second mating portion are not mated with one another, the strength member is at least one of removable from or insertable into at least one of the first portion of the non-conductive sheath or the second portion of the non-conductive sheath.

7 . The insulator support pin of claim 1 , wherein the bore is a blind-end bore.

8 . An insulator support pin comprising a strength member; and a non-conductive sheath surrounding the strength member and extending between a first end and a second end, with the non-conductive sheath defining a bore, with the first end of the non-conductive sheath encapsulating a respective segment of the strength member such that the strength member terminates within the bore so as to not extend beyond the first end of the non-conductive sheath, wherein: the first end of the non-conductive sheath, with the respective segment of the strength member encapsulated therein, is configured to attach to an insulator, the second end of the non-conductive sheath is configured to attach to a support structure, at a first location between the first end and the second end, the non-conductive sheath has a first mating portion, at a second location between the first end and the second end, the non-conductive sheath has a second mating portion and a void is defined at at least one of the first location or the second location, the first mating portion and the second mating portion mate with one another to couple a first portion of the non-conductive sheath to a second portion of the non-conductive sheath, the first portion of the non-conductive sheath extends between and includes the first end of the non-conductive sheath and the first mating portion, the second portion of the non-conductive sheath extends between and includes the second end of the non-conductive sheath and the second mating portion, and when the first mating portion and the second mating portion are not mated with one another, the strength member is at least one of removable from or insertable into at least one of the first portion of the non-conductive sheath or the second portion of the non-conductive sheath.

9 . The insulator support pin of claim 8 , wherein the strength member is non-conductive.

10 . The insulator support pin of claim 8 , comprising a non-conductive support member extending from the non-conductive sheath between the first end and the second end, wherein:

at a first distance from the first end of the non-conductive sheath the non-conductive support member has a first width,

at a second distance from the first end of the non-conductive sheath the non-conductive support member has a second width,

the first distance is different than the second distance, and

the first width is different than the second width.

11 . The insulator support pin of claim 8 , comprising a non-conductive support member extending from the non-conductive sheath between the first end and the second end, wherein the non-conductive support member has a tapered sidewall.

12 . An insulator support pin comprising:

a strength member; and

a non-conductive sheath surrounding the strength member and extending between a first end and a second end, with the non-conductive sheath having a bore at the second end, with the first end of the non-conductive sheath encapsulating a respective segment of the strength member such that the strength member terminates within the bore so as to not extend beyond the first end of the non-conductive sheath, wherein at least one of:

the first end of the non-conductive sheath, with the respective segment of the strength member encapsulated therein, is threadingly configured to attach to an insulator, or

the second end of the non-conductive sheath is threadingly configured to attach to a support structure.

13 . The insulator support pin of claim 12 , wherein the strength member is non-conductive.

14 . The insulator support pin of claim 12 , wherein the first end of the non-conductive sheath is configured to threadingly attach to the insulator and the second end of the non-conductive sheath is configured to threadingly attach to the support structure.

15 . The insulator support pin of claim 12 , wherein the bore is a blind-end bore.

16 . The insulator support pin of claim 12 , comprising a non-conductive support member extending from the non-conductive sheath between the first end and the second end.

17 . The insulator support pin of claim 15 , wherein the first end of the non-conductive sheath is configured to threadingly attach to the insulator and the second end of the non-conductive sheath is configured to threadingly attach to the support structure.
