| Power transformers

Three-phase electrical power transformers are widely used in various applications which require the connection of alternating current networks with withdrawals of high power, generally higher than 10 kVA.

Our company, with over 60 years of experience in the sector of industrial automation, operates in the province of Bologna and throughout the national territory. We specialize in the production, supply and sale ofpower transformers dry for industrial uses, intended for electrical distribution systems, switchboards distribution and other industrial applications.


Main technical characteristics of power transformers:

> Primary tension: customer proposal
> Secondary tension: customer proposal
> Frequency: 50-60 Hz
> Operating temperature: max 40 °C
> Protection degree: IP00 (open)
> Insulation Class: F (155 °C)
> Insulation test voltage: max 5000 V




In our commitment to guarantee the highest quality and safety of our transformers power, we scrupulously comply with current regulations, paying particular attention to the specific requests of the sector:

Double or reinforced insulation: Between the primary and primary windings secondary, we adopt insulation that meets the highest safety standards.

Electrostatic shielding: We implement a shielding layer for ensure insulation between the two windings, with connection to ground to maximize the safety.

Respect for safety distances: In addition to observing distances superficial, we ensure that the insulation is sufficient to cope with the tests of higher applied voltages.

High quality and thermal insulating materials: We use materials valuable and high thermal class insulators to guarantee optimal performance even underneath intense and prolonged loads.

Accurate construction: Every construction detail is executed with precision to satisfy the fundamental requirement of insulation, ensuring maximum safety.

Impregnation for durability: We impregnate transformers for improvement the stability of the insulation characteristics over time, ensuring long life operational.

Terminals suitable for high currents: The input and output terminals are designed to handle high currents safely and efficiently.

Contained voltage drops: We ensure that voltage drops from empty load are kept at a minimum level at the outlet, ensuring distribution stable power supply.

Thanks to our extensive industry experience and our dedication to quality, we we offer the security of having a reliable partner you can count on for your needs power transformers.
