Application fit

Is H07BQ-F right for your machine?

H07BQ-F is selected where standard H07RN-F chloroprene jackets suffer rapid wear from sharp gravel, metal swarf, aggressive cutting oils or sub-zero flexing down to −40 °C.

Trailing & towing

Suitable

Heavy construction site power leads, mobile compressors, generators and workshop machinery dragged over rough concrete or gravel.

Festoon & line chain

Suitable

Round cable loops on crane festoon trolleys and hoist power feeds indoors and outdoors.

Fixed installation

Suitable

Up to 0.6/1 kV when installed in protected conduits, trays or crane switchgear.

Motorised monospiral reel

FAQ

Questions engineers ask first

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

How does H07BQ-F compare with H07RN-F in harsh industrial service?

Both cables are rated 450/750 V under EN 50525-2-21, but H07BQ-F upgrades both layers: it pairs +90 °C EI7 EPR core insulation (versus +60 °C EI4 on standard harmonised H07RN-F) with a thermoplastic polyurethane (TMPU) outer sheath that provides several times higher cut, tear and abrasion resistance than polychloroprene, plus cold flexibility down to −40 °C in motion.

Why is H07BQ-F typically supplied with a bright orange outer sheath?

High-visibility orange (RAL 2003) allows crane operators, forklift drivers and construction crews to spot live trailing cables across muddy trenches, dark tunnels and workshop floors, reducing accidental run-over damage. Yellow and black outer sheaths are also available.

Can H07BQ-F be operated at 0.6/1 kV?

Yes. In accordance with EN 50565-1 and DIN VDE 0298-300, 450/750 V heavy-duty rubber and PUR cables such as H07BQ-F may be operated up to 0.6/1 kV (600/1000 V AC) when installed in fixed, mechanically protected raceways, conduits or crane control gear.

When should I upgrade from H07BQ-F to S07BQ-F?

Standard H07BQ-F is rated for 15 N/mm² dynamic tensile load in free trailing and festoon loops. If the cable runs on a spring-operated or motorised reeling drum or undergoes frequent reversing bends over small sheaves, select S07BQ-F, which adds an anti-torsion support braid under the PUR jacket.
