Your cables are melting, cracking, or failing too soon. You need a wire that survives extreme heat and chemicals without breaking the bank.
If you work in industrial automation, electric vehicles, or marine engineering, you know the pain. Standard PVC cables turn soft in hot environments. They crack when oil or fuel spills on them. They get brittle in freezing cold. When a cable fails, your machine stops. That costs you money in downtime and repairs. You need a cable that doesn’t just carry electricity—it fights the environment around it.This is where the HUBER+SUHNER RADOX 155 series changes the game. We are talking about a 4-core, 6mm² cable built with tinned copper and a special insulation technology. It is not just a wire. It is a shield for your electrical systems. It handles high heat, resists aggressive fluids, and lasts for years where cheap cables fail in weeks.
What makes this 4-Core 6mm² RADOX Cable special?
This specific product is a heavy-duty hook-up wire. It comes in a black jacket. The reel length is 100 meters. The conductor is made of tinned copper. Why tinned copper? Because it does not rust. If you are in a wet or salty environment, bare copper turns green and stops working. The tin coating protects the copper. It ensures a strong connection for a long time.The “4-core” part means you get four separate wires inside one outer jacket. This is perfect for complex circuits. You can use it for 3-phase power plus a ground. Or you can use it for signal and power in the same run. The cross-section is 6mm². This is a thick wire. It can carry a lot of current. We are talking about 10 AWG in American wire gauge terms. It is robust and built for high-power jobs.
The Secret Weapon: RADOX 155 Technology
You might ask, “Why is this better than standard XLPE or silicone wire?” The answer is the RADOX process. RADOX stands for “Radiation X-linked.” Huber+Suhner uses a high-energy electron beam to change the chemical structure of the plastic insulation.Normal plastics melt when they get hot. RADOX plastics do not melt. They are “cross-linked.” Imagine a net. In normal plastic, the chains are loose. In RADOX, the chains are tied together in a tight net. This makes the cable incredibly tough.Here is what RADOX 155 gives you:
- High Heat: It works up to 155°C. Standard wires usually fail at 70°C or 90°C.
- Cut Resistance: It is harder to slice through. This is great for moving cable carriers (drag chains).
- Chemical Resistance: Battery acid, diesel, hydraulic oil—these liquids won’t eat the insulation.
- Thin Walls: Because the material is so strong, they can make the insulation thinner. This means the cable has a smaller outer diameter. It saves space in your control cabinets.

Where should you use this cable?
You should use this cable anywhere the environment is tough. Do not waste it on a simple LED light. Use it where it counts.1. Electric Vehicles (EVs) and Charging StationsEVs get very hot. The battery compartment can hit 100°C or more. Standard wires melt there. RADOX 155 is perfect for connecting battery modules or charging piles. It is also resistant to the coolants and fluids inside the car. It is lightweight, which helps the car go further on a single charge.2. Industrial Robotics and Drag ChainsRobots move. Their cables flex millions of times. Normal cables crack and the copper breaks inside. RADOX is flexible down to -55°C. It bends easily without kinking. It is ideal for moving cable carriers (drag chains) on CNC machines or robotic arms.3. Marine and OffshoreSalt water destroys electronics. The tinned copper and black jacket protect against corrosion. The cable is also flame retardant and low smoke. If there is a fire on a ship, this cable won’t produce toxic gas. It meets strict marine standards.4. Oil and Gas / Process IndustriesIn a refinery, you have oil, fuel, and high pressure. The RADOX sheath is “mud resistant” and “oil resistant.” It won’t get soft if a pipe leaks. It keeps the electricity flowing safely.
Why buy Huber+Suhner instead of cheap alternatives?
You can find cheaper wire on the internet. But cheap wire has hidden costs.
- Quality Control: Huber+Suhner makes this in Switzerland. Every meter is tested. You get a serial number for traceability. If a batch is bad, they know exactly which reel it is. Cheap wire might have thin spots in the copper or bad insulation.
- Safety: This cable is Halogen-free. If it burns, it does not release toxic acid gas. This is a legal requirement in many public buildings and trains.
- Longevity: A cheap cable might last 2 years. A RADOX cable can last 10 or 15 years. You save money on maintenance and replacement.
- Certifications: It has UL and CSA approvals for many versions. It meets EN 50306 standards for railway applications.
How to Order and Pricing
We know you need to compare prices. The price for this specific 4-core 6mm² cable depends on the current copper market (LME price) and the exchange rate between USD and CHF (Swiss Franc). Because it is a specialized product, we usually sell it in full reels of 100 meters.We can also cut it to length if you need specific harnesses, but the standard stock is 100m reels. The weight is significant because of the thick copper and heavy insulation. A reel weighs about 6 to 7 kilograms.Do you have a specific project requirement?Maybe you need a different color for identification? We can check stock for Blue, Red, or Green/Yellow. Maybe you need a screened version (with a braid) to stop electrical noise? We can source RADOX 155 S (Screened) versions too.
