Product Details


The E core are widely used in various transformers like instrument transformers, voltage transformers, inductors, transducers, suppression technology, pulse transformers, chokes and special transformers.

Using high quality CRGO steels with low iron-loss and high permeability in thickness of 0.05mm, 0.08mm, 0.10mm, 0.23mm, 0.27mm, 0.30mm and 0.35mm.

Both standard size like S3U/HWE series and customized E-cores are available at NICORE to satisfy customers’ different demands.

Benefits of E cores

  • Saving in quantity of used copper for winding thanks to smaller dimensions and weight of cut cores.
  • Saving in work costs exert for transformers assembly thanks to easy assembly.
  • Low noise.

Before shipment the cores are re-measure d,we provide the electro magnetic values a t test upon customer’s request.
