Transformer Grade Insulation
Paper Insulated Aluminium Strip for Power Transformers
EC grade aluminium strip wrapped with multiple layers of kraft and thermally upgraded kraft paper insulation for oil-filled transformer windings. A lightweight, cost-effective alternative to copper with 61% IACS conductivity, manufactured to IEC 60076 and IS 13730 standards.
Why Universal Metals
Proven Insulation for Oil-Filled Transformers
EC Grade Aluminium
Electrical Conductor grade aluminium 1350 with 61% IACS conductivity 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.
IEC & IS Certified
Manufactured to IEC 60076, IS 13730, and DIN standards for aluminium transformer windings. Every batch undergoes dimensional verification, insulation thickness measurement, conductivity testing, and dielectric strength validation.
