Go Paperless: 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 dry technologies, HV DryShield® and RIF®, are clearly performing as well or better than alternative cast epoxy, oil or resin impregnated paper, or gas based insulations; it also lasts longer and is being successfully operated up at Extra High Voltages (EHV).

We have created, developed, qualified, and manufactured those two distinct dry type technologies for two distinct functional purposes.

1. HV Dry Shield® for CTs and Wall Bushings
2. RIF® for Transformer Bushings and Cable Terminals
