 Cast resin M.V  current transformers

  TCD3 M.V. outdoor cast resin medium voltgae current transformer, cl:0.5S FS5, 10VA 50Hz, produced according to IEC 60044-1.













  The Transformers can operate and be stored in temperatures between -25°C and 40°C and averase annual humidity more than 75°C in an altitude below 1000m from sea level.

  The body of the transformer is made by a special endurance resin material and filled, designed for outdoor use in areas of high humidity, sun exposure, rainfall, snowfall and high levels of pollution.

  The secondary terminal box is fully rain and moisture proof. The design ensures that moisture due to condensation drains from the terminal box.

  The creep age distance of the product is more than 744mm (Pollution Level IV-Very Heavy). The accuracy class is 0.5

  They are capable of operating with a voltage that exceeds the nominal current by 20%.
