Program Overview
At 132 kV the electric stress inside a cable accessory is many times higher than in distribution systems, and tolerances that are acceptable at 11 kV become critical. Insulation surfaces must be prepared to a fine finish, dimensions held to the millimeter and contamination eliminated entirely. The jointers who do this work carry responsibility for transmission circuits that may supply entire districts.
This program is designed for experienced MV jointers stepping up to transmission voltage. It covers the construction of 132 kV XLPE cables with metallic sheaths, the design of cold shrink joint bodies and terminations, shear-bolt and crimp connector systems for compacted and segmental conductors, and reinstatement of screens and jackets. Practical sessions reproduce real jointing bay conditions, and a dedicated module examines failed terminations to show how preparation errors lead to breakdown.
Learning Outcomes
- Describe the construction of 132 kV XLPE cables, including segmental conductors, semiconductive screens and metallic sheaths
- Prepare 132 kV cable insulation to the dimensional and surface finish requirements of the accessory manufacturer
- Install shear-bolt or crimp connectors suited to round compacted and round segmental conductors
- Assemble cold shrink joint bodies and terminations with correct stress control positioning
- Reinstate screen continuity and re-jacket joints using cold shrink, heat shrink or resin-filled metal housings
- Explain post-installation testing of EHV cables and analyze causes of termination failures

Assessment & Certification
Candidates complete a written examination on EHV cable design, stress control and testing, followed by a practical assessment in which they prepare a 132 kV cable and install a joint or termination under observation against the accessory manufacturer’s instructions. Practical sessions take place at ASEEE-approved training centers.
Successful candidates are awarded the ASEEE competency certificate, issued with a unique certificate ID that employers and clients can verify online through Certificate Check. ASEEE recommends recertification every 2 years to keep competence aligned with current standards, equipment and site practice.
