NSSHOEU 1 KV LOW VOLTAGE FLEXIBLE RUBBER CABLE
Feichun NSSHOEU 1 KV LOW VOLTAGE FLEXIBLE RUBBER CABLE
Application:
For flexible use and fixed installation opencast mining applications, in quarries, on construction sites and CABLE PROPERTIES similar applications, with heavy mechanical stresses. The cables can be used indoors as well as outdoors, in explosion-hazard areas, in industry and in agriculture. They can be used permanently in waste water up to 40°C at a depth of max. 2000 m and in industrial water, cooling water, surface water, rainwater and mixed water - and in groundwater and seawater to a more limited extent. The requirements for accessibility and inspection depend on the consistency of the water. In aggressive water or composed of special substances, the cable’s resistance properties should be tested. In other respects the specifications of DIN VDE 0298 part 3 applies.

CABLE PROPERTIES:
The Feichun NSSHOEU 0.6/1 kV Low Voltage Flexible Rubber Cable is designed for extreme mechanical, environmental, and chemical conditions, making it a trusted solution in opencast mining, quarries, construction sites, wastewater environments, and heavy industry.
What Makes the NSSHOEU Cable Different from Ordinary Rubber Cables?
Unlike general-purpose rubber cables, NSSHOEU is engineered for continuous mechanical stress, permanent water immersion, and aggressive industrial environments.
Key differentiators include:
Tinned finely stranded copper conductors (Class 5) for superior flexibility and corrosion resistance
EPR rubber insulation and inner sheath for electrical stability and waterproofing
CPE (chlorinated polyethylene) outer sheath for oil, UV, ozone, and seawater resistance
Compliance with DIN VDE, IEC, and MSHA standards, enabling global and mining-grade applications
This combination positions NSSHOEU as a heavy-duty flexible power cable, not a light industrial cord.
Can NSSHOEU Be Used in Water, Wastewater, or Underground?
Yes—and this is one of its strongest advantages.
What Water Environments Is NSSHOEU Approved For?
NSSHOEU can be used permanently in water up to 40 °C, including:
Wastewater
Industrial water
Cooling water
Surface and rainwater
Mixed water
Groundwater
Seawater (limited conditions, up to 2,000 m depth)
Accessibility and inspection requirements depend on water composition, and aggressive chemical exposure should be evaluated case-by-case.
What Mechanical Stresses Can NSSHOEU Withstand?
Is NSSHOEU Suitable for Movement and Torsion?
Yes. NSSHOEU is designed for flexible use and fixed installation under heavy stress.
Torsional stress: ±100°/m
Permanent tensile strength: 15 N/mm²
Bending radius:
Fixed installation: 4 × cable diameter
Flexible operation: 5 × cable diameter
These values make it ideal for mobile equipment, pumps, and machinery exposed to vibration or movement.
How Does NSSHOEU Compare with Other Low-Voltage Rubber Cables?
NSSHOEU vs H07RN-F vs NSHTÖU
Feature | NSSHOEU | H07RN-F | NSHTÖU |
|---|---|---|---|
Voltage rating | 0.6/1 kV | 450/750 V | 0.6/1 kV |
Water immersion | Permanent | Limited | Good |
Outer sheath | CPE | EPR | EPR |
Seawater resistance | Excellent | Moderate | Limited |
Mechanical stress | Very high | Medium | High |
Mining suitability | Excellent | Limited | Good |
Conclusion: NSSHOEU is the most robust choice when water, chemicals, and mechanical abuse coexist.
What Cable Configurations Are Available for NSSHOEU?
NSSHOEU is available in single-core and multi-core designs, including:
Single core: 1×16 mm² up to 1×500 mm²
Multi-core: 2 to 12 cores
Configurations with protective earth (-J) or without earth (-O)
Combined power and auxiliary conductor designs (e.g. 3×50/25)
This flexibility allows engineers to optimize cable selection for power, control, and space constraints.
What Should Be Considered During NSSHOEU Installation?
Installation Best Practices
Respect minimum bending radii, especially during cold conditions
Avoid sharp edges and uncontrolled pulling forces
Verify water chemistry when used in aggressive or contaminated fluids
Ensure proper strain relief for moving equipment
Following DIN VDE 0298-3 installation rules significantly extends service life.
