POWER Sp. z o.o. is a young and a dynamic Polish manufacturer of magnetic cores for all types of transformers, transformer components and accessories with more than 10 years of experience.
The company’s first product, magnetic cores are completely manufactured at POWER. Sp. z o.o. factory, remaining one of its core products.
Types of cores manufactured by POWER. Sp. z o.o. include:
• Magnetic cores for 3-phase cast resin, dry-type and oil-filled transformers and reactors
• Magnetic cores for single phase cast resin, dry-type and oil-filled transformers and reactors
• Magnetic cores with 5 legs for converter transformers
• Magnetic cores for chokes

Furthermore POWER Sp. z o.o is manufacturing forced cooling systems, permitting the correct dissipation of the heat produced by dry type transformers and providing a temporery power gain up to 40% from the rated power of the transformer.
We recommend using forced cooling systems together with temperature relays PWR07 or PWR08 (suitable for PT100 or PTC sensors), which monitor temperature inside the windings and switch on and off the forced ventilation when necessary, as well as controlling device PWR12, which diagnoses motor faults in the ventilation system by detecting changes in the current it consumes.
Additionally we can supply Anti-vibration pads, which are a smart, compact and inexpensive solution to reduce vibration and noise level of a transformer. POWER Anti-vibration pads are mounted under the transformer wheels to reduce the level of its noise and vibrations. According to the internal tests, anti-vibration pads manufactured by POWER. allow to achieve a reduction in noise emission of up to 2-3 dB (A) from the nominal value. This can make a difference at places where noise and vibrations can be very disturbing, such as schools, hospitals, offices, apartment buildings, etc.
