This lead wire conductor is a bare copper conductor stranded as per ASTM B8. These conductors are soft, flexible, and lightweight, making hook wires easy to install by folding and bending them without using excessive effort. 

Copper is well known for its good electrical conductivity due to good tensile strength, thermal conductivity, and creep resistance. Therefore, it is no doubt that this hook up wire will ensure a smooth power transmission in your wiring systems for a longer time.


Reinforced insulation is provided by a PVC jacket, which is sunlight-resistant, per ICEA S-97-682 and UL Standard 1072.
