Is Your Production Line Stopping Because of Bad Cables?
You know the feeling. You hear a loud “pop” or see a spark. Then the machine stops. The whole line stops. You check the control cabinet and find the wire is broken again. Or maybe the signal is jumping around on the screen. The motor is shaking. You are losing money every minute the machine is down.This happens because you are using the wrong cable. Standard wires are too stiff. They break when they bend in the drag chain. They get crushed by the machine movement. Cheap shields do not stop noise. Electrical noise from other machines messes up your control signals.You need a wire that moves like a snake but protects like a tank. You need a cable built for constant motion. You need a cable that lasts for years, not weeks. This is why we built this specific 5-core 2.5mm² shielded wire. It solves the breaking problem. It solves the noise problem. It keeps your factory running smooth.
What Makes This 5G2.5 Cable Special?
This is not just a regular power cord. This is a specialized servo wiring harness cable. We built it for high-flex applications. The “5G2.5” code means it has 5 cores. Each core is 2.5 square millimeters in size. This size is perfect for medium to high power servo motors.The “G” stands for flexible conductor. We do not use solid copper. Solid copper cracks when you bend it. We use many tiny strands of copper twisted together. This makes the wire very soft. It can bend millions of times without breaking.The “Imported” standard refers to the quality control. We follow strict Japanese industrial standards. Specifically, we look at the Nichiai drag chain specifications. Nichiai is famous for making the best drag chains in the world. Their standards for cable bending radius and tensile strength are very high. Our cable meets these tough rules. It works perfectly inside Nichiai or similar brand drag chains.
Technical Specs You Can Trust
We believe in transparency. You need to know exactly what you are buying. Here are the hard numbers for this 600V 5-core shielded cable:
Conductor Details
The core of the wire is the most important part. If the core breaks, the machine stops.
- Material: Tinned Copper. We tin the copper with a thin layer of tin. This stops the copper from rusting or oxidizing. It also makes soldering easier.
- Structure: Fine stranded. It is not one solid rod. It is Class 5 flexible stranding. This gives it maximum flexibility.
- Size: 2.5 mm². This handles high current well. It is suitable for motors up to several kilowatts.
- Color Code: We follow standard colors. Usually, you will see Black, White, Red for power, and Green/Yellow for ground. The shield drain wire is often Blue or Bare Copper.
Insulation and Jacket
The outside of the wire protects the inside. It must resist oil, chemicals, and crushing.
- Insulation Material: PVC or PUR. PVC is standard and cost-effective. PUR (Polyurethane) is premium. PUR is much better against oil and abrasion. If your factory has coolant or oil on the floor, choose PUR.
- Jacket Color: Orange is common for servo cables. We can also do Black or Grey.
- Temperature Rating: -20°C to +80°C (for PVC) or up to +105°C (for PUR). It handles heat from the motor well.
- Bending Radius: 8x to 10x the cable diameter. This means if the cable is 12mm wide, it can bend in a curve as tight as 100mm. This saves space in your cable chain.
Shielding Performance
Electrical noise is the enemy of precision. VFDs (Variable Frequency Drives) create a lot of noise.
- Shield Type: Copper Wire Braid + Aluminum Foil. We use a double shield. The foil covers 100% of the core. The braid covers the foil.
- Coverage: > 85% coverage. This blocks almost all external electromagnetic interference (EMI).
- Drain Wire: We include a tinned copper drain wire. This wire connects the shield to the ground. It carries the noise away safely.
Voltage and Electrical Data
- Rated Voltage: 600V (U0/U). This is standard for industrial control systems in the US and Europe (UL and VDE standards).
- Test Voltage: 2500V. We test every batch at high voltage to ensure no weak spots.
- Resistance: Low resistance means less heat. Our copper is pure, so resistance is very low.
Where Should You Use This Cable?
You can use this wire in many places. But it shines in tough environments.
Servo Motors and CNC Machines
This is the #1 use case. Connect the servo motor to the driver. The cable goes inside the drag chain. The machine moves fast. It accelerates and stops quickly. The cable twists and turns. Our high-flex design handles this dynamic motion. It does not tangle. It does not snag.
Robotics and Automation Arms
Robot arms have many joints. The cables in the arm wrist need to be very thin and very flexible. Our 5-core cable is compact. It carries power and encoder signals in one line. This reduces clutter in the robot arm.
Food and Beverage Packaging
In food factories, cables get washed down. They need to resist water and cleaning chemicals. The PUR jacket option is great here. It is hydrolysis resistant. It does not get sticky or crack when washed with hot water.
Textile and Printing Machines
These machines run fast for long hours. Vibration is a big problem. Loose wires cause vibration. Our tightly stranded conductors reduce micro-vibrations. The robust jacket prevents the wire from slapping against the chain.
Why Buy From Us?
We are not just a trader. We are a factory with over 30 years of experience. We know wires. We do not sell cheap junk that fails in a month.##### Quality ControlWe test everything. We check the copper purity. We check the insulation thickness. We do a spark test on every meter. If there is a tiny hole in the insulation, we reject that section. You get a perfect cable every time.##### CustomizationNeed a different length? We cut it. Need a special connector? We crimp it. We can add M23 connectors, Siemens connectors, or just leave the ends stripped. We can print your logo on the jacket. We can make the cable orange, black, or blue.##### Fast DeliveryWe know you need this wire to fix a broken machine now. We keep stock of common sizes. For standard 5G2.5 cables, we ship within 3 days. For custom orders, we usually ship in 10-15 days. We use DHL, FedEx, or sea freight for big orders.##### PriceWe are a direct manufacturer. There is no middleman. You get the factory price directly. We offer discounts for bulk orders. If you buy more than 1000 meters, the price drops significantly.
