The SAi10z is intended for ensuring protection of Conductors and Insulators against indirect lightning strikes, installed on Sectionand Termination Poles.
The SAi10z needs to be installed in association with an Metal-Oxide-Arrester.
The Operational Principle is based on the EasyQuench Technology.
Using the resistance of the ground between two poles, only one device needs to be installed per Pole.
This advantage makes the SAi10z a very cost effective solution to protect against more than 80% of the lightning issues.
