Pfisterer High Voltage Surge Arresters
Pfisterer HV- Connex Surge Arresters - 10kA Type 72.5 - 145 kV
Pfisterer HV-CONNEX dry-type pluggable surge arrester for 72.5 kV voltage level.
Due to the HV-Connex surge arrester insulation and field control made from solid silicone, no liquids or insulating gases relevant for the environment are present. Therefore the installation and operation of the high voltage surge arresters is particularly easy because it does not require regulations for pressure vessels to be followed and gas monitoring is not necessary. Pfisterer HV-Connex surge arresters are easy to remove or replace and save on space.
The Pfisterer Connex system allows for high levels of flexibility in design, commissioning and use of the transformers and GIS.
