COURSE OVERVIEW:

The integrity of the distribution network is fundamentally dependent on the quality of its cable joints and terminations, which represent the most common points of failure in underground systems. This course provides a comprehensive technical guide to the principles and practices of Medium Voltage and Low Voltage jointing, focusing on the precision required to maintain insulation continuity and mechanical strength. Participants will explore the material science of modern jointing kits, including heat-shrink, cold-shrink, and resin-filled technologies.

The scope of this training addresses the critical steps in cable preparation, emphasizing the management of electric stress and the maintenance of a moisture-proof seal. It covers the technical differences between jointing various cable types, such as XLPE, EPR, and paper-insulated lead-covered cables. The curriculum provides a detailed focus on the mechanical and electrical connection of conductors, including the use of compression lugs and shear-bolt technology to ensure low contact resistance and long-term thermal stability.

Coverage includes the rigorous testing and inspection protocols necessary to validate the quality of a joint before backfilling. Attendees will learn to identify common jointing errors that lead to tracking and partial discharge, providing a framework for troubleshooting and failure analysis. By combining manual dexterity with a deep understanding of cable physics, the course equips professionals with the expertise required to produce reliable distribution-side joints that maximize the lifespan of underground cable assets.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Describe the fundamental purpose and requirements of a cable joint.
• Execute professional cable stripping and preparation for MV and LV cables.
• Apply stress control technologies to manage electrical fields in MV joints.
• Install heat-shrink and cold-shrink joints and terminations correctly.
• Implement resin-casting techniques for LV branch and straight joints.
• Utilize compression and shear-bolt connectors for conductor joining.
• Maintain the continuity of cable screens and armoring in joints.
• Identify and prevent moisture ingress through effective sealing methods.
• Perform insulation resistance and high-voltage tests on completed joints.
• Troubleshooting the causes of joint failure and thermal overheating.
• Understand the specific requirements for jointing dissimilar cable types.
• Implement safe work practices, including trench safety and gas detection.

TARGET AUDIENCE:

This course is intended for Cable Jointers, Distribution Electricians, Maintenance Technicians, and Site Supervisors responsible for underground network construction.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
