Introduction

A real High Voltage reliable Dry type insulation
“Dry” insulation is not a new concept in electrical grid equipment. However, the initial designs have been associated with longevity problems and medium voltage limits.

For the first time a dry technology, HV DryShield®, is clearly performing as well or better than any alternative epoxy, oil, or gas based insulation; it also lasts longer and is being successfully operated up to 550 kV.
