The core "lifeline" of the transformer—the internal lead wire of the high-reliability copper stranded wire
Core Advantages
Extreme Conductivity, High Efficiency and Energy Saving
Utilizing over 99.95% high-purity oxygen-free copper, with a conductivity exceeding 100% IACS, effectively reducing internal transformer losses and improving overall energy efficiency.
Superior flexibility, worry-free installation
The multi-strand precision twisted structure gives it excellent flexibility and fatigue resistance, easily handling the challenges of wiring within complex enclosures, significantly improving installation efficiency and reliability.
Reliable, stable, and long-lasting
(Optional tin plating process) Excellent oxidation and corrosion resistance, able to withstand thermal expansion and contraction and electrodynamic shocks during operation, ensuring long-term safe and stable operation of the transformer.
Full Range of Specifications, Customization Available
We offer a full range of standard specifications from 10mm² to over 3000mm², and support custom-made special models with special cross-sections, tin plating, paper insulation, etc., to meet your personalized design needs.
