Precision Copper Solution For High-Performance Transformer Systems

Litmus Paper Insulated Copper Conductors are precision-manufactured copper strip conductors wrapped with high-quality paper insulation the most commonly used winding conductor in the manufacture of power transformers and large electrical equipment. Designed for applications where high thermal performance, reliable insulation, and precise dimensional accuracy are critical, these conductors are available in single, double, and triple paper-covered configurations to meet the varying insulation requirements of different transformer designs and voltage classes.

Litmus Paper Insulated Copper Conductors are produced from high-purity annealed copper strips, precision-rolled to exact dimensional tolerances before undergoing controlled paper lapping in single, double, or triple layers. Each conductor is tested for dimensional accuracy, conductor resistance, paper coverage uniformity, insulation integrity, and thermal performance ensuring they meet the stringent requirements of transformer manufacturers who depend on consistent, fault-free winding conductors.
