FAQ

Questions engineers ask first

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

How do S07BB-F and S1BB-F differ from standard H07RN-F rubber cable?
H07RN-F uses EPR insulation ('R') with a chlorinated polychloroprene outer sheath ('N') limited to -25 °C mobile flexing, whereas S07BB-F and S1BB-F use +90 °C cross-linked EPR ('B') for both insulation and outer sheath, delivering halogen-free safety, +90 °C conductor ampacity, and mobile cold flexibility down to -40 °C.
What is the difference between S07BB-F and S1BB-F?
S07BB-F is rated at 450/750 V AC (tested at 2.5 kV AC) in alignment with EN 50525-2-21 H07BB-F, while S1BB-F upgrades the radial insulation wall to a full 0.6/1 kV AC rating (tested at 3.5 kV AC) for heavy industrial and single-core power distribution.
When should S1BN8-F be selected instead of S1BB-F?
Select S1BN8-F whenever the cable operates in heavy mineral oils, diesel fuel, or AD8 permanent water submersion, as its polychloroprene ('N8') outer jacket offers higher hydrocarbon and flame resistance than halogen-free EPR ('B'). 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.
Is a screened version of S07BB-F / S1BB-F available for VFD motor connections?
Yes, S05BC4B-F, S07BC4B-F, and S1BC4B-F add an ≥ 85 % optical coverage tinned copper braid screen ('C4') between the inner bedding and the EPR outer sheath. 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.
