Tired of cables that crack, break, or cause downtime?
You know the feeling. You install a cable on a crane, a mining rig, or an outdoor event. Everything works fine for a week. Then, the movement starts. The cable gets stiff. It cracks. Water gets in. Suddenly, your whole system stops. You lose money every hour the machines are down. You need a cable that moves when you move it. You need a cable that survives mud, water, and rough handling. You need the German WUPP standard 4 core 50mm2 flexible cable. This is not just a wire. It is a heavy-duty power line built for the real world.
What makes this 4G50 cable special?
This cable is built like a tank but moves like a snake. We call it the “German WUPP” type because it meets the high standards of European heavy industry. It uses a special mix of PVC (Polyvinyl Chloride) material. Why PVC? Because it resists oil, acid, and weather. It does not get stiff in the cold. It does not melt in the heat.The “4 core 50mm2” part tells you exactly what you get. You have 4 separate copper wires inside. Each wire is 50 square millimeters thick. That is a lot of power. You can use three wires for the power and one for the ground (earth). Or you can use all four for power. It is flexible. This means you can pull it through tight pipes. You can wrap it around reels. It does not kink. It is perfect for “cable reeling” and “hoist” applications. If you have a machine that moves, this cable moves with it.
Technical Specs: The numbers you need to know
You need hard data to make a decision. Here is the breakdown of this 4 core 50mm2 flexible cable:
Conductor Material
- Material: High-quality tinned copper.
- Why Tinned? It stops rust. Even if water gets in, the copper stays shiny and conductive.
- Structure: Flexible strands. This is not a solid stick. It is many tiny wires twisted together. This stops metal fatigue when you bend the cable.
Insulation and Sheath
- Insulation: PVC (Polyvinyl Chloride). Color is usually Black.
- Sheath: PVC outer layer. It is tough. It resists abrasion. If you drag the cable over rocks, it does not tear easily.
- Voltage Rating: 0.6/1kV (600/1000 Volts). This is standard industrial power.
- Temperature Range: From -25°C to +60°C (or higher depending on the specific mix). It works in freezers and hot factories.
Physical Details
- Core Count: 4 Cores.
- Cross-Section: 50 mm².
- Outer Diameter: Approximately 28mm to 35mm (varies by brand).
- Weight: Around 1.8 kg to 2.7 kg per meter. It is heavy because it uses real copper and thick rubber.
- Standard: Meets DIN VDE standards, IEC 60227, and European harmonized standards like H07RN-F.
Where can you use this cable? (Real World Scenarios)
You might ask, “Is this cable right for my job?” The answer is yes if you work in hard places. We see this cable used in five main areas.
Mining and Quarries
Mines are dirty. They are wet. They are full of rocks. This cable is used for “mining MSR” and “protolon” type applications. It powers the cutters and the conveyor belts. The PVC sheath stops the sharp rocks from cutting the wire. It is also flame retardant. If there is a spark underground, the cable does not spread the fire.
Cranes and Hoists
Imagine a crane lifting a heavy container. The cable hangs down. It swings. It gets pulled up and down. A normal cable would snap. This “cranes, reeling and hoist cable” is built for constant motion. It handles the mechanical stress. It is often used with cable glands like “SKINTOP” to keep water out of the control box.
Agriculture and Farming
Farming is not just mud. It is chemicals. Fertilizers and manure are corrosive. This cable is used for “agricultural efficiency.” It powers the irrigation pumps and the automated feeders. It resists the chemicals in the soil. It is also UV resistant. The sun does not crack the outer skin.
Construction and Events
Need power for a construction site? Or a music festival? This cable is great for “temporary installations.” It is flexible enough to roll out quickly. It is tough enough for trucks to drive over (with a ramp). It handles the “heavy mechanical stress” of a busy site.
Industrial Machinery
In factories, machines vibrate. Vibration loosens connections and breaks wires. This cable is used in “assembly lines” and “steel mills.” The flexible copper strands absorb the vibration. The cable stays connected. Your machine keeps running.
Why choose the “German WUPP” style?
“WUPP” refers to the high standard of engineering from Germany (specifically the Wuppertal region). This region has a history of making cables for the hardest jobs. When you buy a German-style cable, you are buying peace of mind.
Quality Control is Strict
Factories in Wuppertal use their own labs. They test every batch. They check the “tensile strength.” They check the “elongation at break.” They check the insulation resistance. If a cable is 1 meter too short, they reject it. If the copper is not pure enough, they reject it. You get a certificate with your order.
It Lasts Longer
Cheap cables use recycled plastic. It cracks in winter. It gets sticky in summer. This cable uses high-grade elastomers and PVC. It has a “memory.” If you bend it, it goes back to shape. It does not get twisted or kinked. This means you change the cable once every 5 years, not once every 6 months.
Custom Options
Do you need a screen (shield) for data signals? We can add a copper braid screen. Do you need it to be submersible? We can use a special “Hydrofirm” sheath. Do you need a specific color for safety? We can make the sheath Blue or Orange. The production is “highly flexible.” We can make short runs (even 500 meters) or huge container loads.
How to handle and install this cable
You have the cable. Now how do you use it right?
- Don’t pull too hard: Even strong cables break if you yank them. Use a winch or a lubricant if pulling through a long pipe.
- Bend radius: Do not bend it into a sharp corner. Keep the bend radius at least 8 times the cable diameter. If the cable is 30mm wide, give it 240mm of space to turn.
- Seal the ends: Use proper cable glands (like LAPP SKINTOP or similar). Water is the enemy. If water gets into the copper, it oxidizes. The resistance goes up. The cable heats up. It fails. Seal it tight.
- Storage: Keep it on a reel. Do not leave it in a pile on the ground. Do not leave it in the direct sun for months without covering it.
Compare: PVC vs XLPE vs Rubber (EPR)
You might see cables made of XLPE or EPR. Which one do you need?
- PVC (This Cable): Cheaper. Very flexible. Good for low voltage (under 1kV). Resists oil and chemicals well. Best for general industry, mining, and agriculture.
- XLPE: Handles higher heat. Good for higher voltage. But it is stiffer. It is harder to bend. Best for fixed wiring in walls or underground.
- EPR (Rubber): The toughest. Handles extreme cold (like -40°C). Handles extreme heat. Best for very heavy mining or offshore oil rigs. But it is more expensive.
For 90% of jobs—cranes, farms, standard factories—PVC is the best choice. It gives you the best balance of price, flexibility, and durability.
Frequently Asked Questions (FAQ)
Q: Is this cable armored?A: Usually, this specific “flexible” type is not armored with steel wire. Armor makes the cable heavy and hard to bend. If you need armor for underground burial without concrete, look for “SWA” (Steel Wire Armored) versions. But for moving machines, non-armored flexible is better.Q: Can I use this for 3-phase power?A: Yes. Use 3 cores for the phases (L1, L2, L3) and 1 core for Earth/Ground. It is perfect for 3-phase motors.Q: What is the difference between H07RN-F and H07VV-F?A: H07RN-F is rubber/elastomer sheathed (tougher, more oil resistant). H07VV-F is PVC sheathed (standard). The “German WUPP” style often meets or exceeds H07RN-F standards for flexibility and strength.Q: How fast can you ship?A: Because the factory in Wuppertal is efficient, they can do short setup times. For standard items, we can ship in 7-10 days. For custom colors or printed text on the cable, it might take 15-20 days.
