Abstract

An installation tool and methods for installing a splice kit for a heating cable is provided. The installation tool includes a body, a first channel, and a first cavity. The first channel is defined in the body and configured to retain a first insulating tubing of the splice kit. The first cavity is within the first channel and configured to retain a first connector of the splice kit. The body is configured to retain the first insulating tubing and the first connector in a predetermined formation during installation of the first insulating tubing and the first connector to the heating cable, and the body is further configured to be removed from the first insulating tubing and the first connector following installation of the first insulating tubing and the first connector to the heating cable.

Claims (44)

1. An installation tool for installing a splice kit for a heating cable, the installation tool comprising:

a body;

a first channel defined in the body to retain a first insulating tubing of the splice kit, the first insulating tubing receiving a conductor of a first section of the heating cable; and

a first cavity within the first channel, the first cavity retaining a first connector of the splice kit, the first connector electrically connecting the conductor of the first section of the heating cable and a conductor of a second section of the heating cable,

the body retaining the first insulating tubing and the first connector in a predetermined formation during installation of the first insulating tubing and the first connector to the heating cable, the body being removable following installation.

2. The installation tool of claim 1 and further comprising a second channel defined in the body and configured to retain a second insulating tubing of the splice kit; and

a second cavity within the second channel, the second cavity configured to retain a second connector of the splice kit,

wherein the first channel and the second channel are aligned parallel to each other to receive parallel conductors of the heating cable.

3. The installation tool of claim 2 , wherein the first cavity and the second cavity are positioned at different lengths along the first channel and the second channel, respectively, so that they are not adjacent each other.

4. The installation tool of claim 1 and further comprising an interior retainer and an exterior retainer configured to retain the first connector within the first cavity.

5. The installation tool of claim 4 , wherein each of the interior retainer and the exterior retainer comprises a protrusion that extends inwards towards the first connector.

6. The installation tool of claim 5 , wherein the interior retainer is configured to apply a first force at an angle approximately orthogonal to a first surface of the first connector, and the exterior retainer is configured to apply a second force at an angle approximately orthogonal to a second surface of the first connector.

7. The installation tool of claim 1 and further comprising a tubing retainer within the first channel, the tubing retainer and the first channel impinging on a majority of an outer surface of the first insulating tubing when the first insulating tubing is retained within the first channel.

8. The installation tool of claim 1 , wherein the body comprises a single piece construction.

9. The installation tool of claim 8 , wherein the body is formed by injection molding.

10. The installation tool of claim 1 and further comprising a wire stripping guide including at least one indicator.

11. The installation tool of claim 10 , wherein the at least one indicator includes:

a first indicator indicative of a position to align a cut end of the heating cable;

a second indicator indicative of a length of an outer jacket of the heating cable to remove starting from the first indicator; and

a third indicator indicative of a length of a primary jacket of the heating cable to remove starting from the first indicator.

12. An installation system for a heating cable, the installation system comprising:

a splice kit comprising:

a connector to electrically connect a first conductor and a second conductor of the heating cable,

a first insulating tubing to receive the first conductor, and

a second insulating tubing to receive the second conductor; and

an installation tool to retain the connector, the first insulating tubing, and the second insulating tubing in a predetermined formation during installation;

the installation tool being removable following installation.

13. The installation system of claim 12 , wherein the connector is a shear bolt connector comprising a shear bolt; and further comprising a hex wrench configured to turn the shear bolt.

14. The installation system of claim 12 , wherein the connector is a shear bolt connector comprising two shear bolts.

15. The installation system of claim 12 , wherein the connector comprises a first end and a second end, and in the predetermined formation in the installation tool, the first insulating tubing abuts the first end of the connector and the second insulating tubing abuts the second end of the connector.

16. The installation system of claim 12 , wherein the installation tool comprising:

a body;

a first channel defined in the body and configured to retain the first insulating tubing and the second insulating tubing; and

a first cavity within the first channel, the first cavity configured to retain the connector.

17. A method of installing a splice kit on a heating cable, the method comprising:

retaining a first insulating tubing within a channel of an installation tool;

retaining a second insulating tubing within the channel of the installation tool;

retaining a connector within the channel of the installation tool between the first insulating tubing and the second insulating tubing;

inserting a first conductor of the heating cable through the first insulating tubing into the connector;

inserting a second conductor of the heating cable through the second insulating tubing into the connector; and

tightening a bolt of the connector to electrically connect the first conductor to the second conductor.

18. The method of claim 17 and further comprising removing the first insulating tubing, the second insulating tubing, and the connector from the installation tool.

19. The method of claim 18 and further comprising covering the first insulating tubing, the second insulating tubing, and the connector with a covering.

20. The method of claim 19 , wherein the covering comprises heat shrink tubing and further comprising shrinking the heat shrink tubing.
