Product Overview: TEBAOFLEX (N)SHÖU-J and (N)SHÖU-O 0.6/1 kV is a heavy-duty flexible rubber-sheathed power cable engineered in reference to DIN VDE 0250-812, uniting Class 5 tinned copper conductors, 3GI3 EPR rubber insulation, GM1b inner rubber bedding, and an oil- and flame-resistant 5GM3 (black) or 5GM5 (yellow) elastomer outer sheath.
1. Application Scope & VDE Mining Duty Boundaries
(N)SHÖU serves heavy mechanical environments where standard H07RN-F cables lack voltage margin or double-sheath impact protection:
- Surface Quarries, Open-Pit Crushing & Tunnelling Support: Flexible 0.6/1 kV feeders for mobile crushers, screens, belt conveyors, dewatering skids, and temporary tunnel distribution boards.
- Heavy Construction, Steelworks & Generator Rentals: Single-core (
(N)SHÖU-O 1×25–300 mm²) and multi-core ((N)SHÖU-J 4G–5G) temporary load-bank, transformer, and festoon loops. - Harsh Wet, Oily & Abrasive Routes: Withstands mud, splash water, hydraulic oils, and sub-zero ambient temperatures down to -25°C mobile (-40°C fixed).
Critical VDE Mining Selection Boundary: Do not conflate unscreened trailing, screened underground coal/hard-rock trailing, and motorized drum reeling. If mine safety rules mandate an earth-fault concentric screen, specify (N)SSCHÖU-J 0.6/1 kV Screened Mining Cable; for continuous high-tension motorized reels, specify (N)SHTÖU-O/J Reeling Cable. See our Mining Cable Application Guide and Underground Mining Cable Selection Guide.
2. Cable Construction (DIN VDE 0250-812 Hierarchy)
Select suffix -J when a green/yellow protective-earth core is required (3G, 4G, 5G), or suffix -O without a green/yellow core (1× single-core or 3×/4× IT-network circuits):

5. Frequently Asked Questions
What is the difference between (N)SHÖU-J and (N)SHÖU-O?
(N)SHÖU-J includes an insulated green/yellow protective-earth core (3G, 4G, 5G, etc.), whereas (N)SHÖU-O has no green/yellow core (used for single-core power leads or ungrounded IT/control circuits).
When should I specify (N)SSCHÖU-J or (N)SHTÖU-J instead of (N)SHÖU-J?
Specify (N)SSCHÖU-J when underground mine safety requires a concentric copper earth-monitoring screen, or (N)SHTÖU-O/J when the cable winds continuously on motorized crane or mine reels.
Should we order black 5GM3 or yellow 5GM5 outer rubber sheath?
Choose 5GM3 black for standard outdoor industrial/construction power, and 5GM5 yellow where high visibility and upgraded tear resistance are needed on quarry benches and dimly lit tunnel walls.
Can (N)SHÖU-O / -J be submerged continuously in mine sumps?
Standard VDE 0250-812 builds handle rain, mud, and splash water; if your pump cable remains permanently submerged, send immersion depth and water temperature so TEBAOFLEX can confirm a submersible-tested compound.
Why is (N) written in parentheses in (N)SHÖU?
Under German cable nomenclature, (N) indicates a construction adapted to DIN VDE 0250-812 (for example, incorporating enhanced 5GM5 yellow sheaths or custom core counts) rather than claiming a blanket VDE mark on every variant.
What details should I provide for a quotation?
Send -J or -O suffix, core count and mm² size, sheath compound/colour (black 5GM3 or yellow 5GM5), movement duty, drum lengths, total meterage, and destination port.
Request (N)SHÖU-J / (N)SHÖU-O 0.6/1 kV Factory Datasheet & Quote
Share your single-core or multi-core schedule, 5GM3 black or 5GM5 yellow sheath preference, and operating duty. TEBAOFLEX will confirm gland OD and factory pricing.
