COURSE OVERVIEW:

The reliability of high-voltage distribution networks is critically dependent on the quality of cable joints and terminations. This course provides a technical deep dive into the engineering of "Cable Accessories," focusing on the management of electrical stress at the interface between cables and equipment. Participants will explore the mechanics of "Stress Control," learning how to utilize geometric and capacitive methods to prevent localized ionization and eventual dielectric breakdown.

The scope of this training addresses the full spectrum of high voltage cable types, with a primary focus on XLPE and EPR insulation. It covers the technical nuances of "Cable Preparation," focusing on the precise removal of semi-conductive layers and the cleaning of the primary insulation to prevent "Carbon Tracking." The curriculum provides a detailed focus on "Cold-Shrink," "Heat-Shrink," and "Push-On" technologies, ensuring that participants can execute terminations and joints that withstand extreme thermal and electrical cycles.

Coverage includes the implementation of rigorous testing and quality control measures required for high voltage cable commissioning. Attendees will learn to utilize "Partial Discharge" (PD) testing and "Very Low Frequency" (VLF) withstand tests to verify the integrity of their workmanship. By combining material science with intensive hands-on methodologies, the course equips professionals with the expertise required to deliver high-performance cable connections that meet the stringent demands of modern power utilities.

COURSE OBJECTIVES:

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

• Define the architecture and "Layered Design" of High Voltage cables.
• Identify the primary causes of "Joint and Termination Failures."
• Execute "Cable Stripping" and "Semi-con Removal" with precision tools.
• Implement "Stress Control" techniques using tubes and tapes.
• Explain the physics of "Electric Field Grading" in cable accessories.
• Apply "Heat-Shrink" components according to manufacturer specifications.
• Install "Cold-Shrink" terminations and joints for XLPE cables.
• Perform "Earthing and Shielding" connections for cable screens.
• Conduct "VLF Withstand Testing" and "Tan-Delta" analysis.
• Utilize "Partial Discharge" (PD) detectors to verify joint quality.
• Manage "Mechanical Protection" and "Waterproofing" of buried joints.
• Interpret "Technical Drawings" and "Installation Kits" for HV accessories.

TARGET AUDIENCE:

This course is intended for HV Cable Jointers, Electrical Technicians, Substation Engineers, and Quality Assurance Inspectors.

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.
