Eltom - Motor drive 110 kV NSO 110 / NSO 110 MH / NSO 110 MM

Motor drives type NSO 110 are designed to close and open disconnectors with high voltage outdoor disconnectors and earthing switches with a rotation angle to be adjusted of 192° and the closing and opening resistance moment does not exceed 800 Nm. The drives are designed for use with disconnectors and earthing switches 72,5, 110 and 220 kV. These are the ideal replacement for manual or pneumatic drives.

simple design
high torque for easy maneuvering of single- and three-pole disconnector assemblies in the most difficult climatic conditions
versatile electrical equipment with auxiliary and control equipment with signaling connector
anticorrosive protection of the casing due to the use of aluminium sheet and painting
