Is your production line stopping because of broken cables?
You know the feeling. You have a high-speed robotic arm or a complex drag chain system. Everything runs smooth for a few months. Then, suddenly, a cable cracks. The signal drops. The machine stops. Your team has to tear everything apart to fix it. This costs you money in lost time and expensive repairs.Standard cables just cannot handle the stress. They get stiff in the cold. They crack when they twist. Oil and coolant eat through the jacket. You need a cable that moves as freely as your machine does. You need a cable built for extreme bending and twisting. You need the LAPP ÖLFLEX® ROBOT 900 P. This is not just a wire. It is a heavy-duty solution for dynamic bending and torsion motions. It is the German-engineered drag chain cable that solves your downtime headaches.
What makes this cable special?
This cable is part number 0028174. It is a star in the LAPP family. The “P” in the name stands for Polyurethane (PUR). This is the outer jacket. Why does this matter? Because PUR is tough. It resists oil, grease, and chemicals. It also handles physical stress better than PVC or rubber.The inside is just as impressive. It has 7 conductors, each sized at 1 sq mm (18 AWG). These are not solid wires. They are finely stranded. This means they are super flexible. They do not snap when you bend them. The conductors are insulated with Thermoplastic Elastomer (TPE). This material has low friction. It lets the wires slide against each other without wearing out.This specific model is unshielded. This makes it lighter and more flexible. It is perfect for power and control signals where you do not have heavy electromagnetic interference (EMI). If you need shielding, you would pick the “DP” version. But for most standard robot applications, this unshielded robotic cable is the best choice. It saves space and weight.
Technical Specifications: The numbers you need
When you buy industrial cable, you need exact data. Here is the hard spec for the ÖLFLEX® ROBOT 900 P 7G1:
- Manufacturer: LAPP (Made in Germany)
- Part Number: 0028174
- Conductor Count: 7 Cores (including ground)
- Conductor Size: 1 sq mm (18 AWG)
- Stranding: Extra fine stranded bare copper
- Insulation Material: TPE (Thermoplastic Elastomer)
- Jacket Material: PUR (Polyurethane)
- Jacket Color: Black
- Nominal Outer Diameter: 9.3 mm (0.366 inches)
- Weight: Approx. 88 lbs per 1,000 ft
- Voltage Rating: 3000V (Test Voltage), 300/500V (Nominal)
- Temperature Range: -40°C to +80°C (Static and Dynamic)
- Bend Radius: 10x cable diameter (approx. 93 mm)
- Torsion (Twist): ± 360° per meter
- Approvals: CE, RoHS, VDE 0281/0282
These numbers prove one thing: this cable is built for harsh industrial environments. The 9.3 mm diameter is small. This helps you save space in tight cable carriers. The ± 360° torsion rating is huge. It means the cable can twist fully around itself every meter without breaking. Most standard cables fail at half that stress.
Where should you use this cable?
You can use this cable anywhere you have moving parts. It is the perfect flexible control cable for robotics. Here are the top use cases:1. Industrial Robots and Welding ArmsRobots in car factories move constantly. They twist and turn. The ÖLFLEX® ROBOT 900 P handles the torsional load of a welding robot arm. It resists the heat and sparks found in welding bays.2. Drag Chains (Cable Carriers)If you use plastic or steel drag chains, this cable is a top pick. It glides smoothly inside the chain links. It does not snag. It resists the abrasion of rubbing against the chain walls.3. Assembly Lines and ConveyorsIn a bottling plant or a packaging line, cables get pulled and bent. This oil-resistant PUR cable stands up to the lubricants used on the machinery. It also handles the constant flexing of moving conveyor belts.4. Material Handling SystemsAutomated guided vehicles (AGVs) use this cable. It is lightweight, which helps the vehicle move faster. It is also tough enough to handle the vibrations of a moving warehouse floor.
Why choose the “P” over standard cables?
You might ask, “Why not just use a cheap PVC cable?” The answer is lifespan. A standard PVC cable might last 6 months in a drag chain. The ÖLFLEX® ROBOT 900 P can last 3 to 5 years.PVC gets stiff in the cold. If your warehouse gets cold, PVC cracks. This cable works down to -40°C. It stays soft and flexible even in freezers or outdoor winter conditions.PVC also swells when it touches oil. This makes the cable jam in the drag chain. The PUR jacket on this cable does not swell. It repels oil. This keeps your drag chain moving smoothly.The abrasion resistance is also better. In a high-cycle application, the constant rubbing wears down standard jackets. The PUR jacket on the 0028174 is engineered to resist this wear. It protects the copper inside from exposure.
Installation Tips for Best Results
To get the most out of this cable, follow a few simple rules. You do not need a special degree to install it.First, check the bend radius. Do not bend the cable sharper than 10 times its diameter. For this 9.3 mm cable, that is about 9.3 cm. If you bend it tighter, you damage the internal structure.Second, watch the torsion limits. This cable can twist 360 degrees per meter. But do not twist it in one spot only. Spread the twist out along the length of the cable.Third, use proper strain relief. Even the best cable needs help at the ends. Use SKINTOP® strain reliefs from LAPP to clamp the jacket. This stops the pulling force from reaching the wires.Finally, keep it clean. Even though it is oil-resistant, wiping off heavy grease build-up helps the cable last longer.
Comparing with Competitors
There are other brands like HELUKABEL or igus®. They make good cables. But LAPP has a reputation for consistency. The ÖLFLEX® ROBOT 900 P is a global standard. You can find replacement parts easily. The color coding is standard (Black with white numbers). This makes it easy for your electricians to connect.Competitor cables might be cheaper upfront. But if they fail, the cost of downtime is much higher. LAPP cables are tested for millions of cycles. They are “set and forget.” You install them, and they work.The 0028174 specific model is a “sweet spot” in the catalog. It has 7 cores, which is common for 3-phase motors with a ground and a couple of signal wires. You do not pay for extra cores you do not need.
Frequently Asked Questions
Q: Is this cable shielded?A: No, this is the unshielded version (0028174). If you need EMI protection, look for part number 0028176 or the DP version.Q: Can I use this outdoors?A: Yes. The PUR jacket resists UV light and moisture. It is rated for outdoor use in industrial settings.Q: What is the price?A: Price depends on the length and current copper market. We sell it by the foot or by the spool (1,000 FT).Q: Do you have it in stock?A: We keep high turnover items like the 0028174 in stock. Lead times are usually short.
