Main advantages

♦Performance and overload

High capacity to support overloads and perturbations.

Excellent performance in case of seismic events and vibrating conditions.

Silence

High efficiency material and special geometry design to reduce noise emission in the buildings applications.

Eco+POWER

No fire risk caused by flammable materials.

No risk of environmental contamination caused by liquid leakages.

Used materials are recyclable.

Savings

High efficiency design, reduced maintenance and installation flexibility in the buldings.

Compactness

Compact design for indoor and special room or box dimensions combining terminals position flexibility.

Resistance

Designed and tested for hard enviromental areas from contaminated zones to low temperatures installations.

FACTORY TEST

For each transformer are prepared and issued a test report, in accordance with IEC 60076. except for routine tests, we also offer type tests and specialised tests to meet all customer requirements. We make what matters work for our customers in a safe and reliable way.

Routine test

Measurement of winding resistance
Measurement of voltage ratio and check of phase displacement
Measurement of short-circuit impedance and load loss
Measurement of no-load loss and current
Separate-source AC withstand voltage test
Induced AC withstand voltage test
Partial discharge measurement

Type test

Lightning impulse test
Temperature-rise test

Special test

Partial discharge measurement
Measurement of sound level
Short-circuit test
