FEATURES
Post insulator with capacitive coupling for air insulated indoor applications.
Thanks to this capacitive coupling, it is possible, through the lateral connection, to get a signal proportional to the network voltage. This signal can be read by a voltage presence indicator box, this device will display with a light if the line is operating.
This insulator is made of red epoxy cast resin with H59/H62 brass fittings. It can be supplied with a safety valve that protects the downstream circuit from overvoltage above 600V.
