Certified HV/MV Cable Splicing, Jointing and Termination Course
Introduction:
This practical and highly interactive course includes practical sessions and exercises where participants carryout HV/MV cable jointing, termination, splicing and testing. Theory learnt in the class will be applied using the latest cold-shrink jointing and termination methods suitable for in-class training. The range of voltage and capacity of power transmitted through cables is showing a steady increase over the years. Environmental concerns, aesthetic issues, lack of transmission corridors and difficulty in routing overhead lines in crowded human habitats are some of the reasons for the explosive growth of cable technology well into the new voltage range. Due to physical limits on cable lengths for manufacturing and packaging, joints in cable become inevitable, particularly in the context of the utility sector. The cables need to be also terminated at sending and receiving end equipment, a very wide variety of them, in utility as well as industry applications and these calls for appropriate cable termination accessories.
Course Objectives:
Upon the successful completion of this practical course, participants will be able to:
- Apply proper techniques in HV/MV cable splicing, jointing, terminating and testing
- Discuss cable jointing and the different types of cables, insulation materials, terminations and joints
- Describe the construction of cables, conductor materials and configurations, the different applications and voltages of cables
- Identify the various types of cable connectors, materials and method of connection
- Apply the theory of joints and terminations
- Calculate stress control and determine the effect of joints and terminations on stress gradients and the areas requiring stress control
- Practice cable jointing, splicing, testing and terminating
- Implement the applicable standards, the types of tests, routine tests and its limitations and the training and certification of personnel involved
- Find reasons for cable failures and perform analysis of failures with a predictive approach
- Apply new trends and technologies utilized in the industry
