LAPP ÖLFLEX® CLASSIC 110 SY/CY 3G1.5 mm² Shielded Control Cable | 3-Core 1.5mm² Double Sheathed | German Quality 300/500V PVC Flexible Copper Wire

Tired of signal interference and cable failures in your factory?

Imagine this. You are running a big production line. Suddenly, a sensor stops working. The machine halts. Your team scrambles to find the problem. It is not the sensor. It is the cable. Cheap cables break easily. They let in electrical noise that messes up your data signals. Or, the insulation cracks because of oil or movement. This downtime costs you real money. You need a cable that works hard, stays flexible, and protects your signals. You need a cable built for the real world, not just a lab.This is where the LAPP German brand shines. We are talking about the ÖLFLEX® CLASSIC 110 series. It is not just a wire. It is a shield for your equipment. Specifically, the 3G 1.5 cable (3-core 1.5 square millimeter) version is a favorite for engineers. Why? Because it has a double layer of protection. It has a shield inside to block noise. It has a tough outer jacket to resist oil, chemicals, and dragging. If you are in industrial machinery, HVAC systems, or robotics, this is the cable you want.

What makes the ÖLFLEX® CLASSIC 110 SY/CY special?

Let us break it down simply. “3G1.5” means three cores (wires) inside. Each core is 1.5 square millimeters in size. This size is the “Goldilocks” of control cables. It is thick enough to carry power and signals reliably. But it is thin enough to stay flexible.The “SY” and “CY” codes tell you about the armor.

• SY Version: This has a tin-plated copper braid shield. It is great for general industrial use. It stops electromagnetic interference (EMI) from messing up your sensitive data.
• CY Version: This is the heavy-duty cousin. It has a transparent outer sheath. You can actually see the shield and cores inside. This is perfect if you need to check for damage without cutting the cable open.

Both versions use PVC (Polyvinyl Chloride). PVC is tough. It resists acids, alkalis, and oils. It is also flame retardant. If a fire starts, this cable does not spread it easily. That is a huge safety plus for public buildings and airports.

Let’s look at the technical guts of the cable

You do not need a PhD to understand these numbers. They just tell you how strong the cable is.

• Voltage: It is rated for 300/500 Volts. This is the standard for most control circuits in machines.
• Conductor: The wire inside is bare copper. But it is not one solid stick. It is made of many tiny wires twisted together. We call this “fine-wire” or Class 5 flexibility. This means you can bend it around corners easily without snapping it.
• Resistance: The max resistance is 13.3 Ohms per kilometer at 20°C. That is low. It means power travels through it easily without getting hot.
• Test Voltage: It is tested at 4,000 Volts (4 kV) between cores. That is a massive stress test. It proves the insulation is solid.
• Temperature: It works from -40°C to +80°C. So, it handles freezing cold winters and hot factory floors.
• Bending Radius: You should not bend it too sharp. For fixed installation, the minimum bend is 10 times the diameter. For moving, it is 20 times. For a 6.7mm cable, that is about 13cm. That is very flexible for a shielded cable.

Here is a quick spec sheet for the 3G 1.5 mm² version:

Where should you use this cable?

This 3-core 1.5 square millimeter double-sheathed shielded control cable is a workhorse. You will find it in places where things move, vibrate, or get dirty.##### Industrial Machinery and Machine ToolsFactories are full of noise. Motors, welders, and drives create magnetic fields. If your control cable is not shielded, these fields create “ghost signals.” Your robot arm might move when it should not. The shield in the ÖLFLEX® CLASSIC 110 blocks this noise. The double sheath protects the cable when it gets dragged through metal chains (drag chains).##### HVAC and Building SystemsHeating, ventilation, and air conditioning (HVAC) systems run 24/7. They need reliable sensors. This cable is perfect for connecting thermostats, dampers, and fans. It is VDE registered, so it meets strict safety codes for airports and stations. It does not emit toxic smoke if burned (low smoke zero halogen options are available in other series, but PVC is standard here for toughness).##### Wind Power and Renewable EnergyWind turbines face crazy conditions. The cables inside the nacelle twist and turn as the blades follow the wind. This cable is “torsion resistant.” It can handle the twisting motion without breaking the copper strands. It is also UV resistant, so if you run it outside, the sun won’t crack the jacket.##### Food and Beverage IndustryThis cable is easy to clean. The PVC jacket is smooth and resists cleaning chemicals. It is also safe for damp environments. If you are building a bottling line or a mixer, this is a safe bet.

Why buy LAPP and not a cheap copy?

You might see cheaper cables online. But ask yourself: What is the cost of one hour of downtime?LAPP has been making cables for decades. They invented the ÖLFLEX® standard. When you buy this German brand, you are buying consistency.

• Copper Quality: Cheap cables use recycled copper with impurities. LAPP uses high-purity copper. This means less heat and longer life.
• Shield Coverage: Some cheap cables have a “lazy” shield with gaps (like 60% coverage). LAPP gives you dense coverage (85-95%). This actually stops interference.
• Jacket Thickness: The outer sheath on a LAPP cable is thick and uniform. Cheap ones have thin spots that wear out fast.

The ÖLFLEX® CLASSIC 110 is also approved by UL and CSA for North America. If you export your machines to the USA or Canada, you need these certifications. This cable has them. It passes the UL Vertical Tray Flame Test. This means it won’t burn down the building if a short circuit happens.

How to handle and install it

Installing this cable is easy because it is flexible. But follow these tips to make it last:

1. Don’t pull too hard: The tensile strength is good, but don’t yank it. Use a cable puller.
2. Watch the bend: Don’t kink it. Keep the bend radius smooth.
3. Ground the shield: This is critical. The shield only works if you connect it to the ground properly. This drains away the noise.
4. Use gland fittings: When the cable enters a box, use a proper strain relief (like SKINTOP® from LAPP). This stops pulling force from hitting the wires inside.
