IM6-PM

24-36kv

The switch has two different posi-tions: close and open, with an effective locking system that prevents incorrect operations.

IM6-PM outdoor switches are contained in stainless steel tanks filled with SF6 gas.

Inside the stainless steel tank is placed the 3-phase switch, which can assume 2 positions: closed and open.

The rotary motion of the shaft is made by an operating mechanism placed on the front.

The stainless steel tank is equipped with a safety valve, which ensures safety in case of failure due to internal overpressure; in addition, a proper manometer assembled inside the operating mechanism and visible from the outside constantly monitors the pressure.

The IM6-PM switch is designed be connected on overhead lines and to be installed in the modern telecontrol networks.

The IM6-PM switch is maintenance free even in harsh environment conditions.
