Introduction to the revolutionary 3D 1TC
transformer technology

Technology Advantages

The revolutionary 3D wound core is the ideal transformer technology. It offers:

  • Balanced magnetic circuits and exciting current in all 3 phases
  • Lower no-load losses
  • Reduced vibrations
  • Reduced in-rush currents
  • Better short circuit withstanding capability
  • Reduced exciting (a.k.a. reactive or no-load) currents

Reduced 3rd harmonic effects and total harmonics distortion

Remarks: All comparisons made using a 225kVA 3D wound core transformer and conventional stacked core under specific operating conditions unless otherwise stated.

Technology Benefits

  • 3D Gold energy saving transformer saves 43% more than standard loss transformer in electricity cost from total transformer loss reductions in 5 years.

5 year Return on Investment (ROI)

  • Price of 3D Gold energy saving transformer minus 5 years electricity cost savings from total transformer loss reductions is equal to price of standard loss transformer.

Lower Total Owning Cost (TOC)

  • TOC of 3D Gold energy saving transformer over a 20 year period is 28% lower than that of standard loss transformer.

Reduced CO2 emissions and trees to offset CO2 emissions

  • The 3D Gold energy saving transformer emits 43% less CO2 and requires 43% less trees to offset CO2 emissions than the standard loss transformer (calculated at 80% average load).

Remarks: All comparisons made using a 1000kVA 3D wound core Gold energy saving transformer (European standard Ao + Ak losses) and conventional stacked core standard loss transformer under specific operating conditions unless otherwise stated.
