MV Testing Facility

Specialist Medium Voltage Testing

for MV Power Cables

Testing Medium Voltage cables is more than just quality assurance: it's about delivering installation longevity and resilience. As the critical link for infrastructure and equipment power even microscopic faults can cause:

  • Accelerated ageing
  • Reduced reliability
  • Reduced operational efficiency

The environmental impact and business disruption that accompanies having to replace these cables is significant.

Testing medium voltage cables means not only constructional tests, and environmental tests such as accelerated UV weathering as applied to all cables, but a range of tests specific to these higher voltage cables, including whole drum tests to confirm the full length of cable is fit-for-purpose.

We rigorously test Medium Voltage drums in our specialist facility, testing to IEC, ICEA, IEEE, EN and other national and international standards.
