This solution is for a Low Voltage – Low Voltage isolation transformer with a nominal power rating of 950kVA, a voltage of 400V to 400V and it is capable to withstand an Impulse Level (BIL) of 10kV.

It is a solution installed in a building where a high level of electrical noise is present in the load due to not linear electronic switching devices, air conditioning etc.; those kind of building usually are data centers , hospitals , etc.

This solution is suitable for this high level of harmonics (equivalent to K-factor 4); it has Class H insulation and a double electrostatic screen for EMC noise rejection between primary and secondary windings.

Windings are manufactured with VPI technology and aluminium conductor.

Installation is indoor IP00, air natural cooled.
