WiseWire® 20 AWG PE20 is a heavy duty, extra high-strength, copper-clad steel wire. A custom grade steel core, metallurgically bonded with a copper cladding, that is uniform and continuous, creating a bi-metal conductor that acts as one and is corrosion resistant. Special annealing and drawing processes are performed during the cladding process to achieve desired engineered benefits of unmatched strength, reliability and durability.
Insulation is a 20 mil, high-density, high molecular weight polyethylene (HMWPE/HDPE). WiseWire insulation is engineered to provide superior water blocking and abrasion properties against underground elements and helps prevent accidental breaks caused by rocks in shifting soil conditions, dig-ins, and corrosion.
