UL rated and in compliance with the TIA-455-82-B Water Penetration Test, HydroBloc cables are ideal for indoor/outdoor applications and for use in wet locations inside conduit. They feature an advanced water-blocked construction, a sunlight- and moisture-resistant jacket and a ripcord for ease of stripping for audio/control versions.The advanced water-block construction of HydroBloc cables starts with a two-ply water-blocking tape for superior protection. In contrast to one-ply tape in which water-blocking polymer is attached to one side of a fiber filament tape, the two-ply tape has the water-blocking polymer sandwiched between two fiber filament tapes, which allows for increased volume of the polymer. In addition, HydroBloc cables utilize water-swellable fillers for added protection.
