ÖLFLEX® CLASSIC 110 CY 4-Core 4mm² Shielded Motor Cable – Transparent PVC Sheath (LAPP 1135504) – 300/500V VFD & Servo Wire

Tired of electrical noise ruining your machine’s performance?

You know the feeling. You install a new motor or spindle. Everything looks good. But when you turn it on, the sensors act crazy. The speed jumps up and down. You get error codes on the VFD drive. Or worse, the cable cracks after a few months of moving around.This happens because of two things: Electromagnetic Interference (EMI) and bad cable quality.Cheap cables let noise in. They pick up signals from other wires. This messes up your data. Also, standard black cables hide problems. You cannot see if the copper inside is damaged until it is too late. If you are using this cable for a 3-phase spindle or a servo motor, you need something better. You need a cable that blocks noise, shows you the truth, and lasts for years.We have the solution. It is the LAPP ÖLFLEX® CLASSIC 110 CY 4-Core 4mm² Shielded Cable (Part No. 1135504). This is not just a wire. It is a high-precision tool for your factory. It is made in Germany. It uses a clear outer jacket so you can see the quality. It has a special shield to stop noise. Let’s look at why this is the best choice for your CNC routers, conveyors, and industrial machinery.

What makes this 4G4 Shielded Cable special?

This cable is built for tough jobs. It is not for simple house wiring. It is for places where machines move, vibrate, and create a lot of electrical “dirt” (noise).Here is the breakdown of the part number 1135504:

• ÖLFLEX® CLASSIC 110 CY: This is the series name. It means it meets high safety standards (VDE). The “CY” means it has a transparent outer sheath.
• 4-Core (4G): It has 4 wires inside. Usually, this means 3 phases (power) and 1 ground (earth).
• 4mm²: This is the size of the copper wire. It is thick. It can handle high current (up to 32 Amps in some setups). It is much stronger than thin 1.5mm² or 2.5mm² wires.
• Shielded: It has a metal mesh around the wires. This catches electrical noise before it escapes.

Why the transparent sheath matters

Most cables are black. You cannot see inside. But this one is see-through. Why is this good?

1. Instant Inspection: You can see the copper wires. If the wire is pinched or cut, you see it immediately. You do not need to strip the jacket to check for damage.
2. Color Coding: The inner wires have numbers printed on them (black with white numbers). This makes wiring easy. You will not mix up Phase 1 with Phase 3.
3. Professional Look: It looks clean in control cabinets where you want to show off the wiring quality.

Technical Specs: The numbers you need to know

When you buy cable, you need real data. Here is exactly what you get with this 4mm² shielded wire:

Electrical Ratings

• Voltage: Rated for 300/500 Volts (U0/U). This is standard for industrial control and motor power. It can handle spikes up to 4000 Volts during testing.
• Conductor: Fine-stranded bare copper (Class 5 flexing). This means it is not a solid stiff rod. It is made of many tiny wires twisted together. This makes it flexible. It can bend and move without breaking.
• Shielding: Tinned copper braiding. This is a woven metal mesh. It has very low transfer impedance. In simple words: It stops noise very well.
• Resistance: The copper weight is high. For a 4mm² wire, you get excellent conductivity. Less heat is wasted.

Physical Details

• Outer Diameter: Approx 13.0 mm to 14.6 mm (depending on the exact version). It is slim for a 4mm² cable. This saves space in your cable chains (drag chains).
• Weight: Around 274 kg per km. It is heavy because it uses real copper and good shielding.
• Jacket Material: PVC (Polyvinyl Chloride). But it is a special mix. It is oil-resistant and coolant-resistant. If your machine leaks oil, this jacket won’t melt.
• Temperature Range:
  • Fixed installation: -40°C to +80°C. It works in freezers and hot factories.
  • Moving/Flexing: -5°C to +70°C. It handles the heat from motors well.

Safety & Approvals

• Flame Retardant: Yes. If there is a fire, it does not spread the flame (IEC 60332-1-2). It self-extinguishes.
• Certifications: VDE (Germany), UL, CSA, CE. This means you can use it in Europe, USA, and Canada.
• EMC: It meets EMC Directives. It does not pollute the electrical grid with noise.

Where should you use this cable?

You should use this 4-core 4mm² shielded cable in places where precision and reliability matter. Do not use it for simple lighting. Use it for:

1. CNC Machines and Spindles (2.2kW to 4kW)

If you have a CNC router with a 2.2kW or 3-phase spindle, this is the perfect match. The 4mm² size handles the power easily. The shielding stops the VFD (Variable Frequency Drive) noise from messing up the data lines (like USB or Ethernet) next to it.

2. Servo Motors and Robotics

Servo motors need clean power. If the voltage dips or noise spikes, the servo loses position. This cable ensures the power stays clean. The flexible design is great for robot arms that move all day.

3. Conveyor Belts and Packaging Lines

In a factory, motors start and stop all the time. This creates voltage spikes. The “CY” jacket resists oil from the motors. The shield stops the motor noise from triggering false sensors on the belt.

4. Heating and Air Conditioning (HVAC)

Large fans and pumps in HVAC systems create hum and noise. This cable is rated for these systems. It is UV-resistant if installed outside, but mostly used inside control boxes.

Why choose the German Standard (LAPP 1135504)?

You might find cheaper cables from other places. But “German Made” means something specific here.1. ConsistencyLAPP has been making cables since 1959. When you order part 1135504, you get the exact same product every time. The copper is pure. The shielding coverage is consistent. Cheap cables might skip a few strands of copper to save money. This leads to higher resistance and heat.2. The “Surge” ProtectionWhile this specific 110 CY model uses standard PVC insulation, it is built to handle “non-linear power distortions.” In simple terms: Modern drives (VFDs) chop up the electricity. This creates sharp spikes. The insulation on this cable is thick enough to handle these spikes without failing early.3. Easy to Strip and TerminateBecause the copper is fine-stranded (Class 5), it is easy to put ferrules (crimps) on the ends. It does not fray like solid wire. This saves your electricians time. They can terminate 10 wires in the time it takes to do 5 with stiff cable.4. Chemical ResistanceFactories are dirty. There is oil, grease, and cleaning chemicals. The PVC outer sheath on the 110 CY is tough. It does not get sticky or brittle when it touches coolant. It stays flexible for years.

How does it compare to other cables?

Let’s look at the competition and why 1135504 wins.

As you can see, the RVVP cables you find on eBay or AliExpress are okay for signals. But for a 4mm² motor power cable, they are weak. They use foil shielding which breaks when you bend the cable. The 110 CY uses a braid. It stays connected even when you flex it 100,000 times.Also, look at the diameter. Some “slim” cables claim to be small. But this 110 CY is already optimized. At ~13mm for 4 cores of 4mm², it fits in most standard drag chains. You do not need to buy oversized chains.

Installation Tips for Best Results

To get the most out of this cable, follow these simple rules:

1. Ground the Shield Correctly: The shielding only works if you ground it. Connect the green/yellow wire (and the braid) to the earth ground at one end usually (the control panel end). If you ground both ends, you can get a “ground loop” hum.
2. Bending Radius: Do not bend it too sharp. The rule is 7.5 times the outer diameter when moving. For this cable (13mm), that is about 10 cm (4 inches). Do not bend it in a 1cm loop.
3. Drag Chains: If using in a moving chain, make sure the chain is long enough. The cable should not be pulled tight. It needs room to move.
4. Separation: Keep this cable away from high-voltage mains (400V+) if possible. Even though it is shielded, keep a gap of 10-20cm to be safe.
