Geo Space manufactures leader wire that provides excellent durability in a variety of configurations. The leader wire consists of tinned copper clad steel or cadmium bronze conductor with polypropylene insulation. After twisting 2, 3, or 4 conductors, an all-weather jacket of polyurethane is applied. During this process, an adhesive filler can be added for extra protection against possible water intrusion through accidental cuts in the outer jacket. Geo Space's ongoing commitment to quality, along with continuous inspection at critical points in the manufacturing process, assures a leader wire that will provide long lasting service even in the harshest of environments. The leader wire is available with metal, molded, or field-installable polyurethane D-loops installed at customer specified intervals. It can be shipped on reels or coiled in cardboard boxes.
