Training the next generation of Cable Jointers in Southern Africa is part of Airshrink-CiP’s vision for a reliable and stable energy grid. In keeping with our continued commitment to development Airshrink-CiP conducted a medium voltage (MV) training session for Transnet Port Terminals in Gqeberha (Port Elizabeth) in October 2024. The first phase of the 11 – 33 kV training was held with attendees from Gqeberha Port Terminal and was conducted according to SAQA unit standards ID 259187 and 259189. All Airshrink-CiP MV training courses include a theoretical and practical section which allows the attendees to better understand the complex field of MV cable jointing. Each attendee is evaluated individually by our EWSETA accredited assessor and provided with feedback on where to improve.
Phase 1
Transnet Port Terminals uses different types of cables such as XLPE, PILC, and EPR (ethylene propylene rubber) used in the manufacture of flexible trailing cables, a CiP recommended4-day training course to ensure that the required cable accessories could be covered. Phase 1 of the course focused on XLPE and EPR cables and their accessories. During the theoretical medium voltage training session, the critical aspects of MV cable jointing and terminating were explained, including but not limited to proper MV cable handling, cable stripping, and MV cable accessory installation. Understanding these concepts enabled the attendees to better perform the essential steps of an effective cable and cable accessory installation. During the practical session the attendees were taught the “tricks of the trade” to make the installation of CiP MV cable accessories, namely 11 kV XLPE joints (CJ3/11X) and terminations (CTI3/11X and CTO3/11X), easier and less time consuming. The function of each kit and its components was explained in detail and the correct way to install each was demonstrated before every attendee installed their own CiP termination and joint (in pairs). Airshrink-CiP’s training manager then evaluated each individual’s hand skills and practical application of the knowledge acquired throughout the course. Copies of the evaluations are kept on file and reports can be provided to highlight areas for improvement for each attendee.
Phase 2
Phase 2 of the training for MV PILC joints and terminations will be conducted in March 2025 and the course will have a very similar structure to Phase 1. On completion of Phase 2 each attendee will be issued with a certificate to reflect their performance during the course. Should an attendee be found competent, they will receive a successfully completed certificate. This certificate indicates that the attendee has demonstrated sufficient skill to convince Airshrink-CiP’s instructor that they can install cable accessories independently and unsupervised. If an attendee is found to be not yet competent, they will receive an attendance certificate indicating that the attendee should work under the supervision of a competent jointer and requires more experience in the field. When the attendee has gained the necessary experience, they can qualify for a practical re-evaluation.
Result
Due to the value identified by Transnet Port Terminals management and the attendees, Transnet is exploring the possibility of including the CiP MV training for 11 –33 kV cable accessories in their established training program for electricians.
