Cable Splicing 2

COURSE DESCRIPTION

This course describes splicing three phase primary cables and secondary cables. It also includes splicing in a length of cable and how to install a secondary splice.

COURSE GOALS

  • Describe “phase matching” three single conductor cables.

  • Describe how to splice in a length of primary cable.

  • Describe how a metallic mesh wire replaces a concentric neutral on a primary cable.

  • Demonstrate how to splice secondary cable.

SUBJECTS AND OBJECTIVES

Three-Phase Single Core Primary

  • Explain the “phase match” for three single conductors, jacketed primary cable splices.

  • Explain why “training” cables for a splice is important.

Splicing in a Length of Cable

  • Describe how primary cable may need to be cut to remove a damaged section of faulted cable.

  • Describe how to install a heat-shrink splice on a primary cable with a jacketed concentric wire layer.

Three-Phase Three-Core Primary

  • Explain three phase primary cable within a single cable jacket and how to identify each phase.

  • Explain how to install a metallic mesh wire as a concentric neutral on a primary cable.

Secondary Cable Splicing

  • Identify differences between primary and secondary cable construction.

  • Demonstrate how to perform a cold-shrink splice,  or a molded mechanical splice, and explain how a heat-shrink splice is done on a secondary cable.
