Power Cables are critical components in utility distribution systems and power plant; their performance significantly affects the system’s overall performance and plays a significant role in network reliability. Insufficient installation and testing of cable joints and terminations are the main reason for electricity failure. Appropriate cable splicing and termination considerably improves cables’ lifetime and prevents damage to downstream electrical equipment.

This workshop is designed to update participants with the latest testing standards, commissioning and diagnosing Medium Voltage power cables. It covers some of the more common and updated aspects of corrective and preventive maintenance of MV cables. This course describes the essential information that any engineer, technician & cable jointer who works in distribution needs to know about cable construction, splicing, installation, selection testing, diagnosis, and fault location. You will also learn cable splicing and termination techniques to help reduce the risk of errors that could cause premature electrical failures.


At the end of this course, participants will gain a clear understanding of:

  • Construction of electrical power cables
  • Different types of cables for various voltage ratings and manufacturing aspects
  • Different types of insulation materials
  • Importance of stress control
  • Cable bonding installation & ampacity
  • The basic principles of cable jointing and terminations
  • Different methods of cable termination and jointing and choosing an appropriate type for every application
  • Different types of connectors and connection methods
  • Installation procedures of MV joint & termination
  • Testing of cables (Type test, Factory Acceptance Test & Site Acceptance Test)
  • Operation & Maintenance of MV cables
  • Failures, failure analysis, and failure prediction
  • Different methods of cable fault location
  • Cable Identification & Tracing


This course is suitable for new and experienced engineering and electrical staff involved in cable design, maintenance, and testing. It is ideal for utility, consultant, and contractor staff responsible for installation, testing and maintaining cable systems, this includes

  • Utility Engineers, Technicians, Electricians & Jointers
  • Maintenance Engineers, Technicians, Electricians & Jointers
  • Construction Managers, Construction Engineers, Technicians & Jointers
  • Building Engineers, Technicians, Electricians
  • Design Engineers
  • Inspectors
  • Project Engineers / Managers


The latest educational methods and strategies are employed. The course is designed to not only give the required fundamental knowledge but also to provide a strong background for all attendees towards practical industrial applications. The course will be highly interactive, with opportunities to advance your opinions and ideas. Participation is encouraged in a supportive environment. To ensure the concepts introduced during the course are understood, they will be reinforced through a mix of learning methods, including lecture-style presentation, open discussion, case studies, simulations, and group work.

Pre and Post-course assessments will be used to measure the effectiveness of this training and the pre and post skill and ability of participants.
