COURSE OVERVIEW:

The integrity of an underground power system is only as strong as its weakest joint or termination. This course provides a technical deep dive into the engineering and craftsmanship required to manage Medium and High Voltage (MV/HV) cable accessories. Participants will explore the mechanics of "Electric Field Stress," learning how to utilize stress-control technology to prevent dielectric breakdown at cable interfaces.

The scope of this training addresses the full spectrum of cable work, from initial preparation and "Shield Stripping" to the application of heat-shrink, cold-shrink, and resin-filled technologies. It covers the technical nuances of "Conductor Joining," including compression and shear-bolt connectors, and the critical importance of moisture sealing. The curriculum provides a detailed focus on the physical "Cleanliness" and "Precision" required to ensure the long-term reliability of underground feeders.

Coverage includes the implementation of rigorous post-installation testing protocols, such as Very Low Frequency (VLF) withstand testing and Partial Discharge (PD) analysis. Attendees will learn to identify common "Splicer Errors," manage "Earthing and Bonding" of cable sheaths, and troubleshoot premature joint failures. By combining material science with hands-on technical skills, the course equips professionals with the expertise required to execute high-quality cable connections that withstand decades of operational stress.

COURSE OBJECTIVES:

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

• Identify the layers of a Modern Power Cable: Conductor to Jacket.
• Explain the role of the "Semiconductive Layer" and "Metallic Shield."
• Execute "Cable Preparation" with technical precision and cleanliness.
• Apply "Electric Field Stress Control" using tubes and tapes.
• Install "Heat-Shrink" and "Cold-Shrink" terminations and splices.
• Utilize "Shear-Bolt" and "Compression" connectors for conductor joining.
• Implement "Moisture Sealing" and "Environmental Protection" for joints.
• Perform "Earthing and Cross-Bonding" of cable shields.
• Execute "VLF Withstand" and "Tan-Delta" diagnostic testing.
• Identify signs of "Partial Discharge" (PD) in aging terminations.
• Troubleshoot "Jacket Faults" using the "Bridge" or "Step-Voltage" method.
• Document "Cable Installation Records" and "Test Certificates."

TARGET AUDIENCE:

This course is intended for Cable Splicers, Jointer Technicians, Electrical Supervisors, and Substation Maintenance Engineers.

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.
