WISEWIRE® is the future of pet containment wire and can be used with any in-ground fence system! WISEWIRE® is not your Dad's copper wire. WISEWIRE® has the same tensile (breaking) strength as 14 gauge copper wire. WISEWIRE® is a heavy-duty, extra high-strength, copper-clad steel wire utilizing a commercial-grade steel-core that is metallurgically bonded with a copper cladding. Uniform and continuous, this cladding creates a bi-metal conductor that acts as one and is highly corrosion-resistant. Special annealing and drawing processes are performed during the cladding process to achieve the desired engineered benefits of unmatched strength, reliability, and durability. 

Insulation is a 20 mil, high-density, high molecular weight polyethylene (HMWPE/HDPE) 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.
