The Hendrix DUAL BLOCK for underground cable prevents water from entering the cable core.
Water can be detrimental to life expectancy in primary cable, as it can lead to premature failure if it reaches the cable core. Hendrix DUAL BLOCK prevents this through its reinforced design. First, a fill compound is continuously applied to the conductor interstices to prevent longitudinal water migration. Second, a powder that swells when mixed with water is applied under the polyethylene jacket to prevent the water from migrating along the neutral wires, under the jacket. Together these two applications provide a reliable barrier that prevents water from entering the cable core.
DUAL BLOCK is an option for all stranded-conductor Hendrix cables.
