GNEE New Material offers a full range of Fully Assembled Cores solutions for voltage levels from 10kV to 1100kV. The Complete Assembled cores produced by GNEE New Material have excellent performance, featuring advantages such as low loss, low noise, low no-load current, high mechanical strength, strong short-circuit resistance, minimal partial discharge, good insulation properties, excellent thermal stability, precise dimensions, small burrs, superior process coefficients, and an aesthetic appearance.

  • The Transformer Core Frame Assembly produced by GNEE New Material are laminated cores made from silicon steel sheets. The laminated cores come in two-column, three-column, and five-column configurations, suitable for various single-phase and three-phase transformers.
  • The Built Core with Frames section is multi-step, which reduces the average coil turns length of the customer's product, lowers impedance and copper loss, and facilitates coil winding.
  • The CRGO Built Up Cores sheet shapes include 45° oblique cut shapes, V-slot shapes, and I-shaped sheets.
  •  GNEE CRGO Assembled Transformer Cores primarily use the fully oblique 7-step staggered joint method, also known as “step-lap” (or “staggered joint”), and are referred to as 7-step staggered joint transformer cores.
  • The complete CRGO assembled cores adopt a completely new fully oblique, seven-step staggered lamination joint method. Compared to conventional joint methods, this Transformer Core Assembly reduces the magnetic flux density at the joints by about 22%, reduces no-load loss by about 3%, decreases transformer noise by 2-3 decibels, and lowers no-load current by about 40%. Seven sheets are laminated at once, greatly improving lamination efficiency. Large transformers use the fully oblique, longitudinally interrupted yoke seven-step staggered lamination joint method, which not only retains these advantages but also makes it easier for customers to disassemble and insert the sheets.
