Is Electrical Noise Killing Your Machine’s Efficiency?
You have a big problem. Your industrial machines keep sending wrong signals. The sensors are acting weird. The control panel shows errors for no reason. You check the wires, and they look fine on the outside. But inside, electrical noise is messing everything up. This is electromagnetic interference (EMI). It stops production. It costs money.On top of that, your installation space is tiny. You try to push a stiff cable into a tight drag chain or a small conduit. It gets stuck. You force it, and the wire breaks. Or maybe the cable is too heavy. It pulls down the moving parts of your robot arm. You need a wire that is thin, light, and tough. You need a wire that stops noise and bends easily.This is why we built the ÖLFLEX® CLASSIC 115 CY 7G0.5. It is not just a wire. It is a shield for your signals. It uses high-quality German engineering to solve your EMI and space problems. It has a pure copper core that stays flexible even in cold weather. The PVC jacket resists oil and chemicals. This is the control cable power cable you need for reliable performance.
What Makes This 7-Core Shielded Cable Special?
This product is a star in the Lapp Group catalog. The article numbers are 1136007 and 1136757. It is a screened PVC control cable with a small outer diameter. Let’s break down why this matters to you.First, the shielding. It has a tinned copper braid. The coverage is 85%. This is a high number. It means the shield catches almost all the interference. It keeps the noise out of your signals. It also keeps your cable from making noise that bothers other equipment. This is critical for data processing and sensor wires.Second, the flexibility. The conductor is Class 5 fine-stranded copper. This means it is not a solid stick. It is made of many tiny wires twisted together. This makes it super flexible. You can bend it around tight corners without damaging the core. The outer diameter is only 7.5mm to 7.8mm. This is small for a 7-core cable. It saves space in your control cabinet.Third, the jacket. It uses PVC (Polyvinyl Chloride). This material is tough. It resists abrasion. It handles oil and grease well. If you work in a factory with coolant or lubricants, this cable holds up. It is rated for -30°C to +70°C. So, it works in freezers and hot machine rooms.
Technical Specs You Need to Know
You need hard data to make a decision. Here are the exact specifications for the 7G0.5 model. We list them clearly so you know exactly what you are buying.
Core and Conductor Details
- Number of Cores: 7. This gives you enough channels for power, ground, and multiple control signals in one cable.
- Cross-Sectional Area: 0.5 mm². This is the standard size for control signals and low-power circuits (up to 300/500V).
- Conductor Material: Bare copper. It has high conductivity.
- Stranding: VDE Class 5. Extra fine wires. This ensures maximum flexibility for moving applications.
- Core Marking: Black with white numbers. There is also a green/yellow protective conductor (ground wire). This makes wiring easy. You don’t need a multimeter to find the ground.
Electrical and Physical Properties
- Rated Voltage: Uo/U 300/500 V. This is the standard for industrial control circuits.
- Test Voltage: 4000 V. It is built to handle surges.
- Shield Structure: Tinned copper braid. The tin prevents corrosion.
- Shield Coverage: 85%. Excellent protection against EMI.
- Insulation Material: PVC.
- Sheath Material: PVC (Gray).
- Outer Diameter: Approx 7.5 mm (depending on the specific batch 1136007 or 1136757).
- Weight: Approx 69 kg of copper per km. Total weight is about 105 kg/km.
- Minimum Bend Radius: 6 x cable diameter. Do not bend it sharper than this, or you will damage the shield.
Certifications and Approvals
- Standards: VDE specifications.
- Compliance: CE Low Voltage Directive.
- Flame Test: IEC 60332-1. It does not spread fire easily.
- Oil Resistance: Yes. Suitable for oily environments.
- Water Resistance: Suitable for damp or wet conditions.
Where Should You Use This Cable?
This wire is a workhorse. You can use it in many places. The reference documents show it is popular in machine tools and HVAC. But the market is changing. The rise of Electric Vehicles (EVs) creates new needs. Here are the best places to use this 7-core shielded cable.
Industrial Machinery and Robotics
This is the classic use. Use it for connecting motors, sensors, and push-buttons. It fits well in drag chains. The small diameter means you can pack more wires into the chain. The shielding stops the motor noise from messing up the sensor data. If you build packaging machines or CNC lathes, this is your go-to wire.
HVAC and Building Systems
Heating, Ventilation, and Air Conditioning systems need reliable control wires. They often run through walls or ceilings where space is tight. The ÖLFLEX® 115 CY is easy to pull through conduits. The PVC jacket handles the humidity in air ducts. It is also great for fire dampers and smoke control systems because of its flame-retardant properties.
Renewable Energy and Wind Turbines
Wind turbines have harsh environments. They vibrate a lot. They get wet and cold. The “drip loop” application mentioned in the references is key. This cable resists UV light and moisture. It is perfect for the control systems inside the nacelle. It connects the pitch control motors to the main controller.
Automotive and EV Manufacturing
Germany is leading in EVs. EVs need complex wiring. They have high-voltage batteries and low-voltage control systems close together. This causes massive EMI risks. You need shielded cables like the 115 CY to keep the infotainment and autonomous driving sensors working correctly. It is lightweight, which helps the vehicle’s efficiency. It is also fire-resistant, which is a must for safety in EVs.
Data and Instrumentation
Use this for audio lines, intercom systems, or measurement equipment. The shield keeps the signal clean. If you are setting up a test bench in a lab, this cable prevents “ground loops” that ruin your measurements.
Why Buy This Specific Model (1136007 / 1136757)?
You might ask, “Why not a cheaper cable?” or “Why not a different brand?”The answer is consistency and quality. Lapp is a German brand. They have strict quality control. When you buy article number 1136007, you get the exact same specs every time. Cheap cables might have thin insulation or bad copper. They fail after a year. This cable lasts for decades.Look at the copper index. It is 69 kg/km. Some fake cables use less copper and more aluminum or steel. That increases resistance. It causes voltage drop. Your equipment at the end of the line might not get enough power. With this pure copper core, you get full power delivery.Also, look at the ease of installation. The “dry lubricant” inside the jacket (mentioned in the construction details) makes it slide easily. You can pull it through long pipes without snagging. This saves your electricians’ time. Time is money.The gray PVC sheath looks professional. It does not get dirty as fast as white rubber. It is easy to print on if you need to label it.
