Frequently Asked Questions
Polar Wire's trailer cable is used for about anything from trailer wiring, DC power distribution, and vehicle upfitting, to robotics. Its superior flexibility and cold resistance make it ideal for outdoor, mobile, and extreme-weather installations.
Rated for 600 volts continuous operation. The insulation and jacket system is engineered to remain flexible from -55°C to 105°C (-67°F to 221°F), ensuring performance in both sub-zero arctic conditions and high-heat environments.
Yes. The proprietary PVC jacket compound is resistant to water, salt, oil, gasoline, acids, chemicals, and UV radiation. It also resists abrasion and flex fatigue, making it suitable for dynamic and outdoor installations.
Typical outer diameters range from 0.57" to 0.88" depending on conductor count and gauge. Refer to product datasheets or contact technical support for precise OD tolerances for a given part number.
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.
