FAQ

Questions engineers ask first

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

How does S07RC4N8-F differ from standard H07RN8-F submersible pump cable?
Standard H07RN8-F is an unscreened 450/750 V AD8 submersible rubber cable, whereas S07RC4N8-F adds an inner elastomeric bedding and an ≥ 85 % optical coverage tinned copper wire braid screen ('C4') for VFD-driven submersible pumps and noise-free sensor monitoring. 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.
Why does the designation begin with 'S07' instead of 'H07'?
Because EN 50525-2-21 only harmonises the unscreened H07RN8-F construction, adding the 'C4' copper braid screen requires the CENELEC HD 361 'S' (national/recognized type) prefix, yielding S07RC4N8-F. 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 selected instead of S07RC4N8-F?
Select S1BC4N8-F when the installation requires a full 0.6/1 kV voltage rating ('1') and +90 °C heat-resistant EPR core insulation ('B') for higher current-carrying capacity or long VFD pump feeders. 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 S07RC4N8-F be permanently submerged in municipal sewage and construction slurry?
Yes, its Type EM2 polychloroprene ('N8') outer jacket resists municipal wastewater, oily sludge, and mechanical abrasion in wet wells at water temperatures up to +40 °C. 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.
