Proven Insulation for Oil-Filled Transformers

EC Grade Aluminium
Electrical Conductor grade aluminium at approximately one-third the weight of copper. Delivers significant material cost savings and reduced transformer weight while maintaining reliable electrical performance for distribution and power transformer windings.
Kraft & Thermally Upgraded Kraft Paper
Standard kraft paper for general transformer applications and thermally upgraded kraft (TUK) paper for higher temperature ratings. Both options provide excellent dielectric performance when oil-impregnated, with superior conformability to aluminium strip contours.
Tested and Certified
Every batch undergoes dimensional verification, insulation thickness measurement, conductivity testing, and dielectric strength validation, with test certificates supplied alongside every drum.
