Is Your Cable Strong Enough for the Job?
You have a big problem. You are working with heavy machinery, a large truck, or a marine vessel. You need a cable that carries a lot of power. Standard wires get too hot. They crack in the cold. The insulation melts. This causes fires. It stops your work. It costs you money. You need a wire that works hard and does not quit.Our 120 sq mm tinned cable is the answer. It is built for extreme jobs. We use high-quality tinned copper. It resists corrosion. It handles up to 800 amps for jump starts. It handles high heat for motor connections. This is not a cheap wire. It is a professional-grade tool. It solves your power problems.
What Makes This 120 sq mm Cable Special?
This wire is thick. It is 4/0 AWG in American size. That is about 0.46 inches in diameter. It weighs 1440 kg per kilometer. This means it is solid copper inside. We tin the copper. Why? Because tin stops rust. If you use this cable on a boat or in a wet factory, it stays shiny. It does not turn green. It conducts power better than aluminum or cheap copper-clad wire.The insulation is top class. We use silicone rubber or EPR (Ethylene Propylene Rubber). It handles heat up to 180°C. Most PVC wires melt at 70°C or 80°C. Our wire stays safe in hot engines. It also stays flexible in the cold. You can install it at -25°C without cracking. It is tough against oil, acid, and salt water.
