Learners will practice cable preparation, connector crimping, installation of cold shrink, heat shrink, and pre-moulded systems, as well as testing and fault diagnosis under supervision.

Practical Activities
  • Cable Preparation and Stripping — Learners practice measuring, cutting, and stripping 11-33kV cables including removal of outer sheath, semi-conductive layer, and insulation using appropriate tools. (16h)
  • Connector Crimping and Cold Shrink Jointing — Learners select and crimp connectors onto conductors, then install cold shrink joint bodies including mastics and tapes per manufacturer instructions. (20h)
  • Heat Shrink and Pre-Moulded Termination Installation — Learners install heat shrink termination kits (stress control tubes, sheds) and pre-moulded slip-on terminations, including lug attachment and sealing. (20h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total
Component Out of Weight
Practical Assignments (rubric-scored) 100% 30%
Daily Average (multiple choice) 100% 20%
Final Test (multi-answer multiple choice) 100% 50%
Final Total 100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

Certificate of Completion

Awarded to delegates who achieve an overall mark of 50% or higher on the Final Total (Practicals 30% + Daily Average 20% + Final Test 50%).

How it works
  • Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
