Screened Drinking-Water Pump Connections in Three Voltage Classes
S05BC4B-F, S07BC4B-F and S1BC4B-F are screened rubber pump cables for electrical equipment in water, including drinking-water installations. The designations identify separate 300/500 V, 450/750 V and 0.6/1 kV voltage classes, with plain Class 5 copper conductors and a tinned-copper braid.
Select the sheath system alongside the voltage class. S05BC4B-F and S07BC4B-F use EPR insulation and EPDM outer sheaths. The S1BC4B-F range uses EPR insulation and an EPR sheath system. Its configurations include single-core, G-type, KON and distributed 3G/3 arrangements, allowing the cable selection to follow the actual motor and protective-conductor connection.
- Select the electrical profile: keep the model, rated voltage and cable-test requirements together.
- Plan the cable entry: compare finished diameter limits, seal range and the fixed or flexible bend requirement.
- Coordinate screening: provide effective braid contact at both cable ends and the specified protective-conductor connection.
The S1BC4B-F configuration tables combine conductor diameter, finished dimensions and reference electrical values. Match these to the pump entry, installed route and circuit design. Specify the selected configuration’s weight with the quotation. Include water composition, motor and drive details, installed length and drinking-water documentation requirements with the enquiry. Support the cable independently of the pump lifting system. Immersion depth and the permitted water-temperature limit are confirmed for the specified project.
For screened drinking-water pump selection, explore the submersible pump cable range; for S05BC4B-F, S07BC4B-F and S1BC4B-F motor-drive planning, read the VFD cable guide.
