100% Copper is utilized in all our conductors for utmost quality and conductivity - we sell absolutely no copper clad wire. We stand by our dedication to quality utilizing only the finest conductor constructions to ensure our wire remains at the peak of performance for industrial excellence.
Class K Stranding refers to the size and number of copper strands we use to construct our wire conductors. Our Class K construction uses 30 AWG copper strands to create our sizes. For more details on how many stands we put in each wire size, check out our Class K Conductors Table. Class K stranding contributes our wire's superior flexibility by flexing with our insulation and increases the conductivity of our by providing more strand surface area.
