Tramo ETV manufactures world-class Inductors.

Whether you call them Inductors, Chokes, Reactors, or Drossels, they all refer to the same thing – improved power quality. To avoid confusion, we will refer to them as Inductors in the following text.

TRAMO ETV is a leading Nordic supplier of inductors and noise limiters for the industry. With manufacturing in southern Sweden, we can offer quick and efficient deliveries. Our broad product portfolio includes inductors ranging from a few kilograms and kilowatts to the upper limit of about 1000 A. We also have extensive experience with both air and liquid cooling technologies.

TRAMO ETV’s inductors are perfect for applications such as variable frequency drive (VFD) operations, motor operations, UPS systems, and situations where disturbances may occur due to high voltage spikes during switching.
Our inductors are made in Sweden and are always optimized according to customer specifications. They are designed for continuous operation and built to meet extremely high reliability standards. Our engineers are always available to guide and assist you as a customer. We offer 3D drawings so you can easily integrate our products into your systems from the design stage.

A characteristic of an inductor is how the winding of copper wire around the iron core can be varied and adapted. For each specific application, the inductor is designed to meet both electrical and mechanical requirements. Commonly, the goal is to suppress the 5th and 7th harmonics in industrial facilities where the harmonic content is too high. This might involve pairing the inductor with various types of converters or frequency-controlled motors. Products using direct current often contain a so-called smoothing inductor, which helps to smooth out the waveform and remove any remaining ripple current.
