HV DryShield® is a proprietary condenser finely-graded insulation using composite materials such as PTFE (Poly Tetra Fluoro Ethylene) as core insulation. A uniformly distributed electric field design eliminates stress points and is complemented with external silicone rubber insulation. A unique combination of design, materials and manufacturing know-how results in a very robust insulation with minimum flashover risk and very low partial discharge and tan? values.
HV DryShield® is used both in our Current Transformers and Wall Bushings.
The HV DryShield® dry condenser graded insulation constitutes the independently sealed, weather proof primary winding of the LRGBJ series Current Transformer or the STB series Wall Bushing
