Description
The series covers single-phase, three-phase and three-single-phase transformers. Windings are made of aluminium or copper, so the material is chosen to suit the size limits of a given order. Thermal class F, H or 200 °C sets the permissible winding temperature, and with it the load margin in a hot room. The K-factor of 4, 9, 13, 20, 25 or 50 shows how large a share of harmonics in the load current, for example from rectifiers and UPS units, the transformer can stand. Standard protection is IP21 or IP31, with IP54 as an option. Anti-seismic and medical versions are also available.
How to choose
First fix the power and the number of phases. Single-phase models go up to 350 kVA and three-phase ones run from 3 to 1600 kVA. Then pick the K-factor from the harmonic content of the load and the winding material. Where better protection against dust and splashes is needed, order IP54 instead of IP21 or IP31. For telecom sites that need high attenuation of interference there is a separate IT series (RS, ARM, ARM2).

FAQ
What power range do the ITT isolation transformers cover?
Single-phase transformers are made for 1–350 kVA and three-phase ones for 3–1600 kVA. The exact rating is chosen for the site.
What input and output voltage do the ITT transformers have?
Input and output are made within 110–960 V at 50/60 Hz. The voltage is set to the customer’s requirements.
What does the K-factor mean for ITT transformers?
The K-factor shows tolerance to load harmonics. Values 4, 9, 13, 20, 25 and 50 are available, and the higher the number, the more harmonics are acceptable.
What protection degree and thermal class does the ITT have?
The protection degree is IP21 or IP31, with IP54 as an option. Thermal class is F, H or 200 °C.
What are the ITT windings made of and are there special versions?
Windings are either aluminium or copper. For special conditions, anti-seismic and medical versions are offered.
