Mining and industrial operations demand cables that can endure extreme mechanical stress, high temperatures, moisture, and chemical exposure. The NSSHÖU Mining & Industrial Cable, designed according to VDE 0250 standards, meets these challenges by providing a robust, flexible, and high-performance power solution for underground mines, open-cast mining, quarries, construction sites, and tunneling projects.
Where Can NSSHÖU Mining Cable Be Used?
1. Mining Applications
NSSHÖU is widely used in underground and open-cast mines as a trailing cable for mobile machinery, conveyors, and power distribution systems. Its high mechanical strength and abrasion-resistant sheaths ensure minimal wear in tunnels and pits.
2. Industrial and Construction Sites
In industrial plants and construction areas, the cable can serve as a robust power supply line for cranes, excavators, and automated machinery, even in conditions of high mechanical stress or temporary exposure to chemicals and water.
3. Quarries and Tunneling Operations
The cable’s flexibility and thermal stability make it ideal for quarries and tunneling applications, where machinery requires frequent movement and reliable power under harsh environmental conditions.
4. Agricultural and Infrastructure Projects
NSSHÖU can be used in agricultural operations for heavy machinery and irrigation systems, providing the dual benefit of flexibility and protection from outdoor elements.
What Are the Key Advantages of NSSHÖU Mining Cable?
High Mechanical Strength: Stranded tinned copper conductors and elastomeric sheaths resist abrasion, tearing, and crushing.
Temperature Resistance: Operates reliably from -25°C to +80°C in flexing conditions, withstanding short-circuit spikes up to 250°C.
Chemical and Oil Resistance: Suitable for industrial environments with exposure to lubricants, oils, and chemicals.
VDE Compliance: Manufactured to VDE 0250 and VDE 0207 standards, ensuring safety, quality, and performance.

The NSSHÖU cable excels in heavy-duty trailing applications where flexibility, temperature tolerance, and mechanical robustness are critical.
Are There South African Case Studies for NSSHÖU Cable?
Yes. NSSHÖU cables have been deployed in South African gold and platinum mines as trailing cables for mobile crushers and tunneling equipment. The results showed:
Reduced downtime due to fewer cable failures.
Extended service life compared to traditional PVC and rubber-sheathed cables.
Improved safety due to compliance with VDE standards and clear color-coded sheathing for visibility underground.
Frequently Asked Questions (FAQ)
What does the designation “3GI3/GM1b/5GM5” mean for NSSHÖU cables?
It refers to the materials used: 3GI3 insulation for cores, GM1b inner sheath, and 5GM5 outer sheath, all cross-linked elastomeric compounds that meet VDE standards.
Can NSSHÖU cable be used in wet or chemical-prone environments?
Yes. The elastomeric sheaths are resistant to water, oils, and chemicals, making the cable suitable for industrial and mining conditions.
How flexible is NSSHÖU for trailing applications?
Very flexible. The tinned stranded copper conductors and elastomeric sheaths allow repeated bending without conductor fatigue.
What is the maximum conductor temperature during operation?
The conductor can handle up to 90°C continuously, with short-circuit peaks reaching 250°C for up to 5 seconds.
How does NSSHÖU compare with rubber-sheathed mining cables?
NSSHÖU typically has higher temperature tolerance, better abrasion resistance, and is fully compliant with VDE 0250 standards, making it more suitable for long-term, heavy-duty applications.
What are common installation mistakes to avoid?
Exceeding the minimum bending radius
Running the cable near sharp edges
Not supporting fixed installations properly
Ignoring temperature limits during installation
How long can NSSHÖU cables last in a mining environment?
With proper installation and periodic inspection, service life can exceed 10 years, depending on operational stress and maintenance.
How Can You Choose the Right NSSHÖU Cable for Your Application?
Identify Current Requirements: Determine the operating load and voltage for your machinery.
Check Environmental Conditions: Consider temperature extremes, wet conditions, chemical exposure, and mechanical stress.
Select Appropriate Cross-Section: Match the cable size to the current rating and installation length to minimize voltage drop.
Decide on Flexing vs Fixed: For mobile equipment, choose a flexible variant; for permanent installations, fixed use is adequate.
Confirm Compliance: Ensure the cable meets relevant VDE 0250, VDE 0207, and local South African standards.
Where to Source NSSHÖU Mining Cable?
Investing in high-quality NSSHÖU Mining & Industrial Cable ensures reliability, compliance, and long-term operational efficiency.
