Is your equipment constantly shutting down because of cheap, stiff cables that crack under pressure?
You know the frustration. You run a factory, a processing plant, or an outdoor installation. You need power and control signals to move smoothly. But the cables you buy keep failing. They get brittle in the cold. They swell up when they touch oil. They are too stiff to bend around corners, forcing your installers to waste hours forcing them into place. Worst of all, they break inside the sheath where you can’t see it, causing expensive downtime.You need a cable that doesn’t just carry electricity. You need a cable that works as hard as your machines do. You need the German LAPP ÖLFLEX® CLASSIC 110 series. This isn’t just a wire. It is a flexible power and control cable built for the real world. It handles oil, acid, wet conditions, and constant movement without complaining. Let’s look at why this specific 7-core 2.5 square millimeter cable is the exact solution for your pain points.
What makes the LAPP ÖLFLEX® CLASSIC 110 7×2.5mm² cable so special?
This cable is a legend in the industrial world. It is a European-style cable, which means it follows strict VDE standards. When you buy this, you are buying peace of mind.First, let’s talk about the build. It has 7 cores, each sized at 2.5mm² (which is roughly 13 AWG). The conductors are made of finely stranded bare copper. Why stranded? Because solid wire breaks if you bend it. Stranded wire flexes. It moves. It survives vibration.The insulation and sheath are made of PVC (Polyvinyl Chloride). But this isn’t cheap plastic. It is a special compound that resists oil, alkalis, and acids at room temperature. If you work in a machine shop where coolants and oils leak, this cable won’t dissolve. It stays tough.It is rated for 500 Volts (some versions go up to 1000V). The temperature range is massive: from -40°F (-40°C) up to 176°F (+80°C). Whether you are in a frozen food processing plant or a hot outdoor control box, this cable handles it.
Technical Specifications: The numbers you need to know
When you are writing your Bill of Materials (BOM), you need exact data. Here is the hard data for the LAPP part number 1119407 (and similar variants in the 110 series):
- Brand: LAPP (German Engineering)
- Series: ÖLFLEX® CLASSIC 110
- Cable Type: Flexible Power and Control Cable
- Number of Cores: 7
- Conductor Size: 2.5 mm²
- American Wire Gauge (AWG): Approx 13 AWG
- Conductor Material: Bare Copper (Stranded)
- Insulation Material: PVC
- Sheath Material: PVC (Gray color)
- Shielding: Unshielded (Also available in Screened/Shielded versions)
- Nominal Outer Diameter: 11.1 mm (approx 0.44 inches)
- Voltage Rating: 500V / 1000V
- Operating Temperature: -40°C to +80°C

- Standard: EN 50525-2-51
The copper weight is about 168 kg/km. The total weight of the cable is around 267 kg/km. This means it is heavy-duty. It’s not flimsy. It has substance, which helps with heat dissipation and mechanical protection.
Where should you use this 7-core flexible cable?
You might ask, “Is this right for my project?” The truth is, if you need power and control in one cable, this is it. The 7-core 2.5mm² configuration is the sweet spot for many industrial applications.
Machine Tools and Production Lines
This is the bread and butter for this cable. It connects the motor to the control cabinet. It sends power to the spindle and signals back to the PLC. Because it is flexible, it is perfect for power chains (cable carriers/drag chains). If your machine moves back and forth, this cable can handle up to 5 meters of travel and millions of bending cycles. It won’t snap.
Wind Turbine Generators (WTG)
This is a niche but critical use case. Inside the nacelle of a wind turbine, cables are subjected to constant torsion (twisting). The ÖLFLEX® CLASSIC 110 is specifically designed for torsion applications. It is often used in the loop of the turbine. If you are in the renewable energy sector, this is the cable you want.
Outdoor and Wet Environments
A lot of customers ask about outdoor use. The standard gray PVC sheath is UV-resistant to a degree, but for direct sunlight, you should use conduit or UV protection. However, the cable itself is perfect for damp and wet rooms. It is suitable for:
- Garden lighting and security systems.
- Outdoor building power (sheds, workshops).
- Jacuzzi and hot tub connections (where moisture is constant).
- Factory floors that are washed down daily.
Control Systems and Data Processing
Since it has 7 cores, you can use 3 for power (L1, L2, L3 or Phase, Neutral, Earth), 1 for a signal, and keep a few spares. Or you can use it for 3-phase motors with a brake. It is widely used in conveyor systems, assembly lines, and measuring technology.
Why choose the “RVV” style sheathed flexible wire?
You used the term “RVV” in your search. In the European standard, we call this ÖLFLEX® CLASSIC 110, but the function is the same. “RVV” generally means a flexible sheathed cable.The key benefit here is ease of installation. Because the outer sheath is flexible, you don’t need special tools to bend it. You can route it through tight spaces in a control cabinet. The gray color makes it easy to identify in a bundle of black wires.Also, the number-coded cores make wiring simple. You don’t have to guess which wire is which. The cores are numbered, so your electricians can wire it up fast and correctly. This reduces labor costs on site.Another big win is the chemical resistance. In industrial plants, you have oils from hydraulic systems and acids from batteries. A standard cable gets sticky and rots. This LAPP cable resists that. It lasts longer, which means you don’t have to replace it every year.
How does this compare to cheap alternatives?
You can find cheaper 7-core cables online. But here is the difference: Consistency.With LAPP, you know exactly what you are getting. The copper is pure. The stranding count is precise. The PVC sheath is mixed to the same formula every time. With cheap imports, one batch might be great, and the next batch might have thin insulation that shorts out.LAPP is VDE approved. This is a German certification that tests the cable rigorously. It checks the tensile strength (15 N/mm²). It checks the crush resistance. It checks the fire behavior.If a cable fails in your machine, the cost of the cable is nothing compared to the cost of the lawsuit or the lost production. LAPP cables are used in safety-critical applications. They are reliable.
Frequently Asked Questions about this product
Is this cable armored?No, the standard ÖLFLEX® CLASSIC 110 is not armored. It has a PVC sheath. If you need mechanical protection for direct burial or rough outdoor use, you should put it in a pipe or use an armored version like SWA (Steel Wire Armored). However, for indoor and conduit use, the PVC sheath is enough.Can I use this for 3-phase power?Yes. With 7 cores, you have plenty of options. You can use 3 phases, 1 neutral, 1 ground, and have 2 cores left for control signals (like start/stop buttons).What is the bending radius?For fixed installation, it is 8 times the outer diameter. For flexible movement, it is 12 times the outer diameter. Don’t kink it too tight, or you will damage the conductors.Do you sell it by the foot or by the drum?We can supply it by the foot (cut to length) or by the drum (1000 ft / 305 meters). We can also put custom labels on it for your project.
