No! We extrude our polarity stripe into our wire to ensure it does not wear off in heavy use.
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.
We designed Arctic Ultraflex Blue® and Arctic Superflex Blue® as a premium product for superior performance.
Premium TPE Insulation
We designed a revolutionary flexible yet durable TPE insulation blend that is designed to perform in harsh cold weather conditions. However, because of it's superior flexibility, Arctic Ultraflex Blue® has become the preferred premium flexible wire in nearly every industry among the most demanding wiring applications.
Class K Stranding
To complement our premium insulation blend, we construct our conductors with 100% copper in a 30 AWG Class K configuration. Using a collection of 30 AWG strands to construct our wire sizes, copper rods must be drawn out to 30 AWG and bunched together to create our conductor. For perspective, our 4/0 AWG construction has over 2000 strands! In addition, we utilize 100% copper stranding ensuring maximal conductivity and performance.
