VSCCB 0.6/1 kV Screened Submersible Pump Cable
VSCCB is a 0.6/1 kV screened rubber cable for wastewater pumps and frequency-converter-controlled AC drives. It combines EPR insulation and sheath compounds with an overall tinned-copper braid.
- Three-core 6, 10 and 16 mm² pump-connection reference dimensions.
- Class 5 flexible copper; tinned up to 6 mm², plain above 6 mm².
- 90 °C maximum conductor temperature.
- Separate fixed-route, flexible-route and entry bend references.

VSCCB for Screened Wastewater Pump Connections
VSCCB is a 0.6/1 kV screened rubber cable for wastewater pumps and frequency-converter-controlled AC drives. EPR-insulated flexible copper phase conductors, a tinned-copper braid and an EPR outer sheath provide a defined screening path around the power circuit.
The pump-connection dimension table covers three-core 6, 10 and 16 mm² configurations. Match the complete diameter range to the seal or gland, then allow room for screen preparation and strain relief. The illustrated three-core construction represents the family material arrangement; the finished cable and entry dimensions belong together in the connection design.
Effective EMC installation requires broad screen contact at both ends, coordinated with the drive, motor and enclosure. Specify the protective-earth path with the equipment design as well as the screen connection. Cable supports should carry the installed lead without transferring pump weight to the entry; use the pump’s designated lifting system for handling.
- Choose the conductor section from motor current, drive output and route length.
- Use the separate fixed and flexible bend factors for the intended route.
- Coordinate the pump-entry bend reference with the seal and termination drawing.
Include wastewater composition, cleaning chemicals, installed length and the controller details with the enquiry. Immersion depth and the permitted maximum water temperature are confirmed for the specified project.
For VSCCB project selection, explore the submersible pump cable range; for VSCCB screen connections, consult the VFD cable guide.
Construction
The representative VSCCB three-core arrangement has three equal phase cores inside an EPR sheath system and an overall metallic braid. Select the phase section and connection details together.
| Element | Construction |
|---|---|
| Phase conductors | Fine-stranded copper, Class 5; tinned up to and including 6 mm², plain above 6 mm². |
| Core insulation | EPR rubber compound. |
| Core identification | DIN EN 50525-1; the illustrated three-core phase arrangement uses brown, black and grey. |
| Inner sheath | EPR rubber in the illustrated material arrangement. |
| Screen | Overall tinned-copper braid between the inner and outer sheath. |
| Outer sheath | EPR rubber compound. |
| Protective connection | Specify the protective-earth path and the screen termination with the equipment design. |
Applications
Screened power connections for wastewater pumps and AC motors operated from frequency converters, with coordinated EMC bonding, sealing and mechanical support.
| Selection point | Requirement |
|---|---|
| Screen bonding | Provide broad, effective braid contact to ground at both connection ends. |
| Protective-earth design | Specify the protective-earth path with the motor and drive connection; coordinate it with the screen termination. |
| Pump entry | Choose the seal from the complete diameter range and allow room for braid preparation and strain relief. |
| Cable route | Use the fixed or flexible bending factor for the intended route and provide independent supports. |
| Entry bend reference | Use the pump-entry radius reference with the sealing and termination drawing; fully flexible routing uses the separate flexible factor. |
| Circuit selection | Supply motor current, drive output, installed length and installation conditions. |
| Water chemistry and duty | Provide wastewater composition, immersion depth and water-temperature conditions with the enquiry. |
