Lamp cable for Ueberall UVK and UBK series ultraviolet units, original part number 28133 (7318). It carries the ballast output to the lamp connector inside the reactor head. Lamp cables in this position are a wear item: they sit warm and damp and are disturbed every time a lamp is drawn, so insulation hardens and connector contacts corrode, which shows up as a lamp that strikes intermittently or an on-and-off lamp-failure alarm while the ballast behind it tests good. This cable is listed against the Ueberall UVK-1, UVK-1L, UVK-2, UBK-1 and UBK-2, and is catalogued at 25 m. Item number 1938-0111. Original part number 28133 (7318). Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
