NICHIGOH 3 Core 1.5 sq mm High Flexibility Drag Chain Cable – CE Certified, UL Listed, Oil & Water Resistant (153m/500ft)

Is your production line stopping because of broken cables?

You know the feeling. You have a high-speed machine, a robot arm, or a conveyor belt that moves all day long. Everything is working fine. Then, suddenly, the system stops. You check the computer, the software is fine. You check the motor, it is fine. Then you look at the cable. It is cracked. The copper is showing. Or worse, it snapped inside the drag chain.This is a nightmare for any factory manager. Downtime costs money. Every minute a machine is down, you lose profit. Cheap cables crack after a few months. They get hard in the cold. They get sticky in the heat. They break when they touch oil.You need a cable that moves as much as your machine does. You need a cable that bends millions of times without getting tired. You need the NICHIGOH 3 Core 1.5 sq mm High Flexibility Drag Chain Cable. This is not just a wire. It is a lifeline for your automation systems. It is built to last 10 times longer than standard PVC cables. Let’s look at why this is the best choice for your factory.

What makes this cable special?

This cable is part of the famous NICHIGOH “World Wide Standard” series. It is made in Japan with strict quality control. But what does that mean for you? It means consistency. Every meter of this cable has the same quality. It does not have weak spots.The “3 Core 1.5 sq mm” part tells you the size. It has three wires inside. One for live power, one for neutral, and one for ground (earth). The 1.5 sq mm size is the “Goldilocks” size. It is not too thick to be heavy, but it is thick enough to carry power for most sensors, small motors, and control systems.But the real magic is the “High Flexibility” and “Drag Chain” design. Standard cables are stiff. If you bend them too much, the copper breaks. This cable uses a special copper alloy and a unique twisting method. The copper strands are very fine. They slide over each other instead of grinding down. This allows the cable to bend into a U-shape over 100 million times. Yes, 100 million! Your machine will probably retire before this cable does.

Technical Specs You Can Trust

We know you need numbers, not just promises. Here is the hard data on this cable.Physical Properties:

• Conductor: Flexible copper (Class 5 stranded). This is the highest flexibility class.
• Cross-Section: 1.5 mm² (approx 16 AWG).
• Number of Cores: 3 Cores (Live, Neutral, Earth).
• Insulation Material: Special PVC or TPE blend (depending on series like RO-FLEX). It is not the hard plastic you find on cheap extension cords. It stays soft.
• Sheath Color: Black or Grey (usually Black for industrial use).
• Outer Diameter: Approx 7.8mm (varies slightly by specific model like RO-FLEX 22775F).
• Bending Radius: 8 times the outer diameter. This means it can turn sharp corners without damage.
• Standard Length: 153 meters (500 feet). This is a full drum, ready for big projects.

Electrical Performance:

• Rated Voltage: 300V / 500V (flexible installation).
• Test Voltage: 2500V for 5 minutes (it can handle high voltage spikes).
• Current Carrying Capacity: At 30°C in air, it can handle about 15 to 16 Amps. If it is in a drag chain or bundled, we usually derate this to be safe. Check the chart, but for 1.5mm, 13-15A is a safe bet for continuous use.
• Conductor Resistance: Max 13.3 Ohms/km at 20°C. This means very little energy is lost as heat.

Environment & Safety:

• Temperature Range: -15°C to 70°C (flexing) / -40°C to 80°C (fixed). It works in cold freezers and hot factory floors.
• Flame Retardant: Complies with IEC 60332-1. If there is a fire, it does not spread the flame easily.
• Halogen Free: Yes. This is critical. If it burns, it does not release toxic smoke. It is safe for people and electronics.
• Oil Resistance: Excellent. It is designed to resist oils and chemicals found in factories. The sheath does not swell or get hard when it touches machine oil.

Where can you use this cable?

You might think “cable is cable,” but in the real world, the wrong cable causes failures. Here are the best places to use this NICHIGOH cable.Robotics and Automation:This is the #1 use. Robot arms have wrists, elbows, and shoulders. They twist and turn all day. A normal cable will snap in a week. This NICHIGOH cable is designed for “reciprocating motion.” It moves back and forth, up and down, forever. It is perfect for the internal wiring of robot arms and pick-and-place machines.Drag Chains (Cable Carriers):If you have a CNC machine, the cable goes inside a plastic chain that drags along the track. The chain moves fast. The cable inside rubs against the chain links. Cheap cables get ground down by the plastic. This cable has a smooth, tough sheath that resists abrasion. It glides inside the chain instead of getting stuck.Conveyor Systems and Logistics:In a big warehouse, packages move on belts. Sensors and scanners are on the moving parts. The cable connecting them needs to flex thousands of times a day. This cable handles that constant movement easily.Marine and Outdoor Use:Water and electricity do not mix. But this cable is built tough. It is water-resistant and dust-proof (IP67 rated connectors are available). It is great for boat wiring, outdoor lighting systems, and security cameras exposed to rain. The UV-resistant sheath stops the sun from cracking the plastic.Construction Sites:Construction is rough. Cables get dragged over concrete, stepped on, and bent around corners. The “Fine Diameter” feature of NICHIGOH cables makes them easy to pull through pipes. They are about 10% slimmer than standard cables, so you can fit more cables in a conduit.

Why choose NICHIGOH? The Safety Factor

Safety is not a joke. A bad cable can cause a fire or electrocute a worker. NICHIGOH takes safety very seriously.Certifications that Matter:You need to pass inspection in your country. This cable has you covered.

• CE Mark: Mandatory for Europe. It meets the EU safety standards.
• UL / cUL Listed: Essential for North America (USA and Canada). UL tests the cable for fire and shock hazards.
• CCC: Mandatory for China.
• VDE: German standard for quality.
• RoHS Compliant: No lead, no mercury, no bad stuff. It is eco-friendly.

Low Smoke and Gas:In a modern building, air quality matters. This cable has “Low Gas Emission.” It does not release smelly or toxic gases (outgassing) that make people feel sick. This is vital for hospitals, schools, and offices.Fire Retardant:We mentioned IEC 60332-1. This means if a short circuit happens, the cable chars but does not burst into flames. It stops the fire from spreading to other machines.

Comparison: NICHIGOH vs. Cheap Generic Cable

Let’s be honest. You can buy cheaper cable on the internet. But here is what you get with the cheap stuff vs. what you get with NICHIGOH.

You see? The cheap cable looks like a deal. But when your machine stops, the cost of that cheap wire is nothing compared to the lost production. NICHIGOH is an investment in reliability.

Specific Series to Look For
