Transformer Grade Insulation
Paper Insulated Copper Strip for Power Transformers
OFC grade copper strip wrapped with multiple layers of kraft and thermally upgraded kraft paper insulation for oil-filled transformer windings. Strip dimensions up to 5 mm thickness and 3 x 15 mm configuration, manufactured to IEC 60076 and ASTM B152 standards.
Why Universal Metals
Proven Insulation for Oil-Filled Transformers
Oxygen-Free Copper
High-purity OFC copper strip with superior conductivity and minimal oxygen content for reliable electrical performance in transformer windings. Full traceability from cathode to finished strip, with spectrometer-verified composition on every production run.
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 conductor contours.
IEC & ASTM Certified
Manufactured to IEC 60076, ASTM B152, DIN, and IS standards. Every batch undergoes dimensional verification, insulation thickness measurement, conductivity testing, and dielectric strength validation.
