APPLICATION

For underground L2-BUS routes between automation equipment, this cable combines a PVC inner jacket with a PE outer jacket. The screened signal pair uses solid bare copper conductors and foam-skin PE insulation. Its two-jacket construction distinguishes it from the indoor and single-jacket outdoor versions.
