This practical and highly interactive course offers participants the opportunity to engage in hands-on sessions and exercises focused on HV/MV cable jointing, termination, splicing, and testing. The theoretical knowledge gained during the course will be applied using the latest cold-shrink jointing and termination methods, specifically designed for in-class training. Over the years, there has been a consistent increase in the range of voltage and power capacity transmitted through cables. Factors such as environmental considerations, aesthetic concerns, limitations in transmission corridors, and challenges in routing overhead lines through densely populated areas have contributed to the significant growth of cable technology, especially in higher voltage ranges. In the utility sector, cable joints become essential due to physical limitations in cable lengths during manufacturing and packaging. Additionally, cables need to be properly terminated at both the sending and receiving end equipment, which requires a wide variety of appropriate cable termination accessories in utility and industrial applications.
