## Abstract

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.

## Claims

### Claim 1

A process for creating a hot stick comprising:
selecting a foam filled fiberglass pole and creating a recess in a top end of the pole by removing the foam from the top end of the pole to a depth of 2 times an external diameter of the pole;
sealing a top of the foam in the top end of the pole;
creating a thermal insulating part with a first end whose external diameter is created for insertion into the recess in the top end of the pole, and a second end of the thermal insulating part created for insertion into a recess in an end tool;
inserting the first end of the thermal insulating part into the pole and securing it to the pole; and
inserting the second end of the thermal insulating part into the end tool and securing it to the end tool.

### Claim 2 (depends on 1)

A process for creating a hot stick according to claim 1 wherein the thermal insulating part is comprised of Polyether Ether Ketone (PEEK).

### Claim 3 (depends on 2)

A process for creating a hot stick according to claim 2 wherein a length of the thermal insulating part is created to reduce the temperature at the second end of the thermal insulating part to be a maximum of 80 degrees Celsius when the first end of the thermal insulating part is at 250 degrees Celsius.

### Claim 4 (depends on 1)

A process for creating a hot stick according to claim 1 wherein a length of the thermal insulating part is created to reduce a temperature at the second end of the thermal insulating part to be a maximum of 80 degrees Celsius when the first end of the thermal insulating part is at 250 degrees Celsius.

### Claim 5 (depends on 4)

A process for creating a hot stick according to claim 4 wherein the thermal insulating part is secured to the pole using at least one plug inserted through the pole and the thermal insulating part, and the thermal insulating part is secured to the end tool using at least one plug inserted through the end tool and the thermal insulating part.

### Claim 6 (depends on 1)

A process for creating a hot stick according to claim 1 wherein the thermal insulating part is comprised of glass and a length of the thermal insulating part is created to reduce the temperature at the second end of the thermal insulating part to be a maximum of 80 degrees Celsius when the first end of the thermal insulating part is at 250 degrees Celsius.

### Claim 7 (depends on 1)

A process for creating a hot stick according to claim 1 further comprising creating a cover over a transition from the pole to the thermal insulating part and the transition from the insulating part to the end tool.

### Claim 8 (depends on 7)

A process for creating a hot stick according to claim 7 further comprising creating sheds on the cover.
