Course Description
Splices and terminations, which are always a vital part of any cable system, become more susceptible to failure at higher voltages. Whether splicing or terminating is accomplished by the use of hand-applied tapes, a filled or molded device, heat-shrinkable tubing, or a prefabricated device, care should be exercised during the application. Poor workmanship or improper choice of materials could jeopardize the reliability of the entire system. This course covers distribution underground cable accessories from low to high voltage cable from various manufacturers. The course is designed according to the type of cable and cable accessories utilized by participants' companies.
Course Objectives
- Identifying the causes of splice and termination failures
- Utilizing a DC high potential tester for performing dielectric strength tests on assembled splices
- Preparing cable for splicing utilizing hand tools, abrasives and solvents
- Installing taped, cold shrink and molded elbow terminations
Who Should Attend?
- Engineers
