    Product Details

    The IMSA 50-2 LOOP LEAD-IN CABLE contains two, twisted-pair(concentric) annealed, shielded solid or stranded tinned copper (Cu) conductors with polyethylene insulation, aluminum foil/Mylar polyester shielding with a drain-wire loop, and an XPLE (polyethylene) jacket. It has a voltage rating of 600V and uses a tinned copper conductor.

    IMSA 50-2 conductors are surface printed and color-coded black and clear for easy identification. The lay length of this cable type meets all municipal and international traffic wiring and cabling standards.

    The IMSA 50-2 cables are primarily utilized as roadway loop detector lead-in cables for traffic signal systems, in communications circuits with low capacitances such as parking gates and sliding gates, and as underground and aerial operations conduits for various messenger applications. 50-2 is the most highly preferred direct underground burial cabling type by many municipal and international Transportation Departments

    This cable type has an operating temperature range between -55 to 70 degrees Celsius (Centigrade), and its XLPE insulation ensures adaptability to both wet and dry, hot and cold environments. Its lightweight jacketing allows for high-grade water resistance.

    Product Highlights:

    • 50-2 conductors range between 12-18 AWG and are at ASTM B-8 and B-33.
    • 7 and 19 stranding is available for optimal choice and versatility
    • The 50-2 loop lead-in cable works best and is highly recommended in long lead-in projects
    • 50-2 cables have strong resistance to temperature extremes

    Technical Standards:

    50-2               Polyethylene insulated, polyethylene jacketed, loop detector lead-in cable
