Participants will learn why robust cable joints and terminations are critical for dependable electrical connection, mechanical support and network integrity. Emphasis will be on MV-rated XLPE and paper-insulated lead-covered (PILC) cables, covering their theory, construction, preparation, jointing and termination . You’ll engage with manufacturer-specific specifications, stress-control principles and quality assurance protocols to ensure every joint and termination meets performance and safety standards .

Target Market

This course is tailored for:

• Cable Jointers, Electricians and Technicians responsible for MV cable installations
• Electrical Engineers and Supervisors seeking deeper understanding of cable accessory applications
• Maintenance Managers and Asset Reliability Professionals aiming to minimise network downtime
• Contractors and Consultants involved in designing or specifying cable joints and terminations

Course Objectives

By the end of the course, delegates will be able to:

1. Explain MV cable construction and insulation principles for both XLPE and PILC types
2. Interpret and apply manufacturer’s specifications and industry standards to cable jointing and terminating
3. Prepare and strip cables correctly, including semiconductor removal and conductor shaping
4. Install stress-control, sealing and insulation materials using heat-shrink and cold-shrink techniques
5. Execute straight, branch and transition joints on single-core and three-core cables with precision
6. Perform terminations into switchgear and outdoor fittings using mechanical connectors and sealing tubes
7. Use specialized tools (e.g., spiking guns, crimpers, cable strippers) and employ “tricks of the trade” for efficient workflows
8. Conduct MV insulation resistance and continuity tests, plus post-jointing inspections to verify joint integrity
