FAQ

Questions engineers ask first

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

How is the CENELEC designation S05BC4B-F / S07BC4B-F / S1BC4B-F decoded?

Under CENELEC HD 361, 'S' denotes a national-type cable following harmonised construction rules, '05'/'07'/'1' specifies the voltage class (300/500 V, 450/750 V, or 0.6/1 kV), the first 'B' means +90 °C EPR core insulation, 'C4' designates a copper wire braid screen over the assembled cores, the second 'B' means an EPR outer sheath, and '-F' indicates Class 5 flexible copper conductors.

What are the advantages of 'B..B' (EPR/EPR) over 'R..N' (EPR/PCP) rubber cables?

Unlike polychloroprene ('N') which contains chlorine and stiffens below -25 °C, the dual EPR ('B..B') system is completely halogen-free, supports a continuous +90 °C conductor temperature, and remains flexible down to -40 °C in mobile outdoor service. 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 S07RC4N8-F or S1BC4N8-F be used instead of S07BC4B-F / S1BC4B-F?

When the screened cable is exposed to heavy mineral oil immersion, flame-retardant mining duty, or AD8 permanent water submersion, select polychloroprene-sheathed S07RC4N8-F (450/750 V) or S1BC4N8-F (0.6/1 kV). 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 S07BC4B-F and S1BC4B-F be used as VFD motor supply cables?

Yes, the low-permittivity EPR core insulation combined with the ≥ 85 % optical coverage tinned copper braid ('C4') provides effective electromagnetic shielding for variable-frequency motor drives. 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.
