Hendrix Wire & Cable Dual Block

November 2010, Vol. 65 No. 11

Water is one of the enemies of long-life in primary cable, as water entering the cable core can lead to premature failure.

Hendrix Wire & Cable is offering Dual Block to help 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. 603.673.2040, www.hendrix-wc.com
