Water Blocked Cable

Capillary action is the phenomenon of a liquid flowing in narrow spaces without the assistance of, and in opposition to external forces like gravity. In many wire and cable applications water and moisture migrate through the conductors shorting out and permanently damaging electronic circuitry. The result is expensive repair and replacement costs.

The solution? Anti-capillary (water blocked) wire and cable. Our water blocked product consists of bare or tinned copper conductors sealed with a silica blocking agent. The silicone fills the voids between the conductor strands thus blocking the ability of fluid or moisture to seep through. These water-blocked cable constructions are often used in the shipboard industry, outdoor lighting, traffic signal, oil wells, automotive, marine and military applications. Anti-capillary conductors are available in any of the single end or custom cable constructions Hueson produces.
