FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why specify S1BN8-F instead of standard H07RN8-F submersible pump cable?
Standard H07RN8-F is limited to 450/750 V and +60 °C (+85 °C EPR) conductor temperature, whereas S1BN8-F upgrades the voltage rating to 0.6/1 kV ('S1', tested at 3.5 kV AC) and uses +90 °C heat-resistant EPR core insulation ('B') for 15–18 % higher current capacity and 690 V pump motors.
How is the CENELEC code S1BN8-F broken down?
Under HD 361, 'S' indicates a recognized national-type construction, '1' means 0.6/1 kV rated voltage, 'B' designates +90 °C ethylene-propylene rubber insulation, 'N8' specifies an AD8 permanent-submersion polychloroprene outer sheath, and '-F' denotes Class 5 flexible copper conductors. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
When should S1BC4N8-F be chosen over S1BN8-F?
Choose S1BC4N8-F when the 0.6/1 kV submersible pump or industrial motor is powered by a variable-frequency drive (VFD) or requires an overall tinned copper braid screen ('C4') for electromagnetic compatibility. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
Can single-core S1BN8-F cables be used in parallel on large flood-control pumps?
Yes, single-core S1BN8-F cables from 50 mm² to 185 mm² are widely installed in trefoil groups on high-capacity storm-water, dry-dock, and mine dewatering pumps. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
