The webinar aims to give introduction to the Technical Brochure of Maintenance of HV cable systems.


Maintenance of high voltage (HV) cable systems, and accessories, is an important practice to ensure the availability of a cable system during service. Generally, cable systems have an expected lifetime of several decades depending on various factors such as age, insulation type, voltage, and operating history. To ensure the cable system is utilized in a safe and expected manner, maintenance of the system is required. This can be achieved through inspection, testing, diagnostics and/or monitoring of the cable system.
