FAQ

Questions engineers ask first

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

How does S07BQ-F differ from standard H07BQ-F?

While H07BQ-F is a single-sheath EPR/PUR cable for free trailing, S07BQ-F ('S' for special construction) adds an extruded elastomeric inner sheath and a high-tenacity synthetic anti-torsion braid underneath the outer TMPU polyurethane jacket. This dual-sheath braided structure prevents corkscrewing on spring and motorised cable reels and raises dynamic tensile capability to 20 N/mm².

Why use S07BQ-F on spring-driven cable reels instead of NSHTÖU?

Spring reels on service trucks, construction cranes and cold-climate machinery benefit from a lighter, smaller-diameter cable with extreme surface cut and abrasion resistance. S07BQ-F's TMPU polyurethane jacket slides smoothly through roller guides, resists sharp gravel and stays flexible down to −40 °C.

Can S07BQ-F be used for 0.6/1 kV industrial equipment?

Yes. Like H07BQ-F, S07BQ-F is rated 450/750 V for general mobile duty and up to 0.6/1 kV (600/1000 V AC) in protected installations and crane switchgear per DIN VDE 0298-300 / EN 50565-1.

What travel speeds and drum diameters are recommended for S07BQ-F?

S07BQ-F is rated for reeling travel speeds up to 60 m/min with a minimum dynamic bending radius of 6 × OD. For faster portal crane drums up to 120–180 m/min at 0.6/1 kV, specify our TRA PUR reeling cable or NSHTÖU.
