Direct Burial Jacket Custom Cable’s proven solution for your water block- ing needs. REPEL™ cables are first constructed using a premium grade jacket com- pound which is flame retardant, sunlight resistant and water resistant and has been developed to be durable in outdoor and direct burial applications. In addition to the jacket, REPEL™ cables utilize a superior water-blocking tape, rather than the messy gel, which swells to absorb any moisture that is present. The special formulated tape stops water in its tracks by blocking migration of moisture throughout the cable.
