Application fit

Is NSSHÖU right for your machine?

NSSHÖU is engineered for very high mechanical stress under DIN VDE 0298-3 in mines, tunnels, quarries and heavy industrial plants — select O/J for general power/control, 3E for individually earth-screened phases, or 3E+ST where pilot monitoring cores are required.

Fixed installation

Suitable

Fixed and semi-fixed mining, quarry and industrial power in dry, damp, wet and outdoor zones (4 × OD bend; 50 N/mm² pull).

Trailing & towing

Suitable

Mobile equipment leads and trailing connections for drilling rigs, TBMs and quarry crushers (5 × OD flex; 15 N/mm² tension).

Immersion & wet locations

Suitable

Suitable for permanent submersion in fresh water, salt water, storm water, oily water and sewage-contaminated water down to 100 m depth.

Motorised monospiral reel

Not suitable

Continuous motorized drum reeling with reverse bending and torsion requires a purpose-built anti-torsion reeling cable.

What is the difference between NSSHÖU-J, NSSHÖU-O, NSSHÖU 3E and NSSHÖU 3E+ST?

Under DIN VDE 0250-812, NSSHÖU-J and NSSHÖU-O are unscreened power and control cables: -J includes a green/yellow protective-earth (PE) core, while -O omits the green/yellow core (including single-core and 3+3E split-earth cables). NSSHÖU 3E adds an individual concentric tinned-copper screen (braid up to 10 mm², helical wires from 16 mm²) over each of the three phase cores so that the split earth encloses each phase radially. NSSHÖU 3E+ST further adds three insulated Class 5 tinned-copper pilot/control cores (3 × 1.5ST or 3 × 2.5ST) in the outer core interstices for earth-continuity and interlock monitoring.

Can NSSHÖU be used on motorized cable reels or energy chains?

Standard NSSHÖU is designed for fixed installation (4 × OD minimum bend radius, up to 50 N/mm² pulling load during laying) and heavy-duty mobile/trailing connection (5 × OD free flexing, up to 15 N/mm² tensile load per DIN VDE 0298-3). It does not contain an anti-torsion braid between the inner and outer sheaths. For continuous motorized drum reeling or high-cycle crane/spreader travel where torsion and reverse bending occur, specify NSHTÖU 0.6/1 kV reeling cable instead.

Why does the NSSHÖU datasheet show two different 3 × 50 + 3 × 25/3E rows?

In the specification table, sizes 3 × 50 + 3 × 25/3E through 3 × 240 + 3 × 120/3E appear first under the unscreened multicore group (where three reduced-section earth cores are laid in the interstices between the three unscreened phase cores, e.g. OD 36.3–37.5 mm for 3 × 50 + 3 × 25/3E) and again under the individually screened NSSHÖU 3E group (where the 25 mm² earth is divided into three concentric copper wire screens wrapped around each 50 mm² phase core, OD 39.8–41.5 mm). Specify '3E unscreened' or '3E individually screened' when ordering.

Is NSSHÖU suitable for wet underground workings and submersible pump feeds?

Yes. The combination of cross-linked 3GI3 EPR insulation, extruded GM1b inner sheath and heavy-duty 5GM5 polychloroprene/elastomer outer sheath is certified for dry, damp, wet and outdoor service, resists mineral oils and greases (EN 60811-404 / DIN VDE 0472-803 Test A), and is rated for permanent submersion in fresh, salt, storm, oily and sewage-contaminated water to a depth of 100 m.
