How do high-voltage cables hold up after being in operation for 40 years?

From shield resistance to sheath testing

Explore the results of a meticulous examination of high-voltage cables with Stefan Eklund, Service Technician at Nexans. Together with the Electrician Podcast, he takes us on a technical journey where we assess the cable's condition after 60 years in operation, from shield resistance to sheath testing.

What happens to high-voltage cables after four decades of service?

This question is answered in our latest YouTube episode with the Electrician Podcast, where Stefan guides us through a meticulous evaluation of the cable's condition.

• Shield Resistance: Measures how well the cable protects against interference and signal loss.
• Tangens Delta Measurement: Assesses insulation quality and detects material degradation.
• Sheath Testing: Ensures the protective sheath of the cable remains intact and effective.
• Ground Connection Check: Verifies proper grounding for safe operation.

The findings from this investigation not only enhance our understanding of cable aging but also provide crucial insights for future cable management and maintenance strategies. 

Come along and learn more about the unsung heroes of our electrical system – high-voltage cables that keep our modern society running smoothly.
