Dry Type Transformers - Low Voltage - Ultra Insulated
TR-HI - Single-phase or Three-phase

Ultra Isolation transformers are electromagnetic devices that decouple electronic instrumentation noise control in existing manufacturing lines. Thus the sensitive instrumentation is isolated from noise.

These characteristics are obtained benefiting the construction of the transformer in order to:

  • Get yourself a maximum rejection of common mode noise;
  • Minimize the noise-transverse mode, which results in common mode noise between the winding and ground;
  • Reduce to the maximum electromagnetic noise emanating from the transformer.

Magnetic Separator Coils

The application of high intensity magnetic separators is extremely important in ore separation.

Designed to work in wet or dry processes, these separators are based on the difference in magnetic susceptibility between magnetic and non-magnetic materials, enabling their separation. This process allows the segregated material to be reused as an intermediate product, making the process more efficient.

Separator boxes can be assembled in stainless steel or carbon steel, according to each customer's needs.

The internal coils generate a high magnetic field gradient and are composed of aluminum wires insulated with material with high dielectric strength, mechanical flexibility and high thermal resistance (thermal class "H" - maximum working temperature 180 °C). The coils are cooled by fans coupled to the end of the box, thus ensuring the thermal dissipation of the set.
