A strong and flexible solution for your large distribution transformer
- Direct and remote control available.
- Customizable shaft length.
- Microswitches for positioning monitoring available.
- Motor Drive Unit applicable.
|Voltage class||24 kV, 36 kV, 52 kV, 72,5 kV|
|Rated current||from 120 A up to 600 A|
|Number of positions||from 2 up to 11 positions (up to 20 positions for special applications)|
|Available connections||bridge, linear, star, series/parallel, star/delta|
Strong and extremely flexible in the variants offered, 020 series allows to reach a maximum amount of 11 positions for standard applications. As for very special applications, the number of positions can be increased up to 20, thanks to the possibility of customizing the product.
Shaft can be placed at one side or between the phases. The change of position is allowed by a complete rotation of the shaft, which ensure a high precision and avoids any desplacement.
The drive equipment can be integrated with mechanical block, electrical block and/or microswitches for remote control.
Motor Drive Unit (MDU) is also available as an option and it is guaranteed for 20.000 maneuvres with no extraordinary maintenance.
Contacts are available in different versions: threaded, tubular or flag-shaped. For rated currents at 600 A, contacts are always silver-plated as a standard solution to ensure better conductivity and resistance.
