Low to High Voltage Cable Splicing and Terminations

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 Hands-On 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 your company.

Equipment Requirements
(This apply's to our hands-on courses only)

Client is to provide their specific Splice Kits (1 Splice Kit per student-suggested) and the specific cable for splicing for the Hands-On portion of the training.

BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
