Application fit

Is H07RN-F right for your machine?

H07RN-F is the European harmonised workhorse for portable power and medium-to-heavy mechanical stress. For continuous submersible pump duty specify H07RN8-F; for high-speed motorized crane reeling specify NSHTÖU.

Trailing & towing

Suitable

Mobile site distribution boards, generators, welders, portable saws, drills and temporary event power.

Fixed installation

Suitable

Fixed installation on plaster, in temporary buildings, machinery frames and up to 0.6/1 kV inside enclosed conduit.

Festoon & line chain

With conditions

Light workshop hoists and short crane loops at ≥ 7.5 × OD over guide rollers; use NGFLGÖU for dedicated flat festoons.

Cylindrical / multi-layer drum

With conditions

Intermittent cable drums at ≥ 5 × OD within the 15 N/mm² pull limit; not for high-speed crane reeling.

Immersion & wet locations

Not suitable

Standard EN 50525-2-21 H07RN-F is rated for damp/wet locations; continuous submersible pump service requires AD8-tested H07RN8-F.

Use H07RN8-F submersible cable

Motorised monospiral reel

Not suitable

lacks an anti-torsion braid between inner and outer sheaths; high-cycle crane drums will corkscrew it.

Use NSHTÖU reeling cable

FAQ

Questions engineers ask first

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

What does the harmonised designation H07RN-F stand for?

Under EN 50525-1, H denotes a CENELEC harmonised cable, 07 indicates the 450/750 V nominal voltage rating, R specifies ethylene-propylene rubber (EPR type EI4) core insulation, N specifies a polychloroprene (PCP type EM2) outer sheath, and -F denotes a flexible Class 5 finely stranded copper conductor.

When can H07RN-F be operated at 600/1000 V?

In accordance with EN 50565-2 and DIN VDE 0298, H07RN-F is rated 450/750 V for general mobile and portable service, but is permitted up to 600/1000 V AC (or up to 750 V DC to earth) when installed in fixed, mechanically protected conduit, trunking or enclosed switchgear.

What is the difference between H07RN-F and H07RN8-F?

Both cables are built to EN 50525-2-21 with EI4 EPR insulation and an EM2 polychloroprene sheath, but H07RN8-F uses a water-resistant sheath formulation tested for continuous AD8 submersion up to 10 m depth in water up to +40 °C for submersible pumps. Standard H07RN-F is intended for dry, damp, wet and outdoor industrial service.

Can H07RN-F be used on motorized crane cable reels?

H07RN-F can be wound on intermittent hand or storage drums at a minimum radius of 5 × OD provided conductor tensile stress stays below 15 N/mm². However, it has no anti-torsion braid; for continuous motorized crane drums or spring reels, specify NSHTÖU.

What is the difference between H07RN-F and 07RN-F sizes?

Sizes covered directly by the CENELEC harmonised tables of EN 50525-2-21 carry the <HAR> mark and the H07RN-F designation. Additional core counts or large multicore combinations outside the harmonised table (such as 37G2.5 or 5G120–5G240) are manufactured to the same construction under national designation 07RN-F.
