Product overview

S1BN8-F is a 0.6/1 kV flexible cable for wastewater pumps, submersible mixers and other electrical equipment in contaminated water. It combines Class 5 plain copper conductors, EPR insulation and a black CPE outer sheath. Power and numbered control configurations are available, with 79 configurations listed in the technical tables.

The sheath system follows the selected configuration. Single-core cables and multicore cables with up to five cores and a cross-section of 6 mm² or less use one CPE sheath. Multicore sizes from 10 mm², and constructions with more than five cores, add a blue EPR inner sheath beneath the black outer layer. The representative 4G25 illustration shows this two-layer construction.

Use the minimum and maximum finished diameter to match the pump gland or sealing sleeve. The size table also keeps fixed and moving bending radii, cable mass, tensile force and current data alongside each configuration. This helps coordinate the electrical selection with the space available at the motor entry and along the supported cable route.

For wastewater service, provide the liquid composition, expected contaminants and inspection arrangement with the enquiry. Send motor current, starting method, cable length, conductor configuration and entry-seal drawings for selection. Water depth and water-temperature limits are confirmed for the project after enquiry. Support and strain relief carry the cable load independently of the pump lifting system.

Applications

Applications

Use this construction for wastewater pump motors and submersible mixers. Match the cable to the actual equipment, route and water medium before selecting the final configuration.

Wastewater pump installation with supported black motor cable and a separate lifting chain
Application illustration: independently supported cable route and separate mechanical pump lifting arrangement.
  • Select power cores or numbered control cores from the exact configuration table.
  • Compare both OD limits with the pump entry seal, rather than matching conductor size alone.
  • Keep wastewater installations accessible for inspection; specify chemical composition and cable support.

Keep contaminated-water routes accessible for inspection. Review aggressive chemicals and varying effluent composition individually. Provide cable support and strain relief separately from the pump lifting system.
