Milford, N.H., July 14, 2010—Hendrix Wire and Cable, a provider of high-quality underground and overhead distribution products, announces its DUAL BLOCK product. This offering provides a dual water blocking capability on Hendrix primary, underground cable.

Water is one of the enemies of long-life in primary cable, as water entering the cable core can lead to premature failure. Hendrix DUAL BLOCK helps prevent this from occurring. First, a fill compound is continuously applied into the conductor interstices. This prevents longitudinal water migration. Second, a water-swellable powder is applied under the polyethylene jacket. This prevents water from migrating along the neutral wires, under the jacket. Taken 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.
