The Hendrix Wire & Cable Dual Block provides dual water blocking capability for underground cable installations.
Dual Block helps prevent water entering the cable core, which can lead to premature failure.
The cable features a fill compound that is continuously applied into the conductor interstices to prevent longitudinal water migration and a water-swellable powder applied under the polyethylene jacket to prevent water from migrating along the neutral wires, under the jacket. These two applications provide a reliable barrier that prevents water from entering the cable core.
An all-stranded-conductor variant of the cable is optionally available.
