Stop Worrying About Cable Failures – Get Power That Stays On
You have a big job to do. Maybe you are wiring a new factory floor. Maybe you are fixing the power grid. Or maybe you are setting up a massive solar farm. You know that one bad cable can ruin everything. If the insulation melts, the machine stops. If the wire is too thin, it gets hot and starts a fire. If the shielding is weak, the signal gets noise and the motor runs wrong. You need a cable that works hard, stays cool, and lasts for years. You do not want to fix the same wire twice. We understand this stress. That is why we built the 4-core 16mm² cable. It is not just a wire. It is a promise of safety and reliability. We make this cable to meet the tough German standards. It handles high power easily. It resists water, oil, and rough pulling. It is the strong link in your power chain.
What Makes This 4G16 Cable So Special?
This is not a cheap wire from a random shelf. This is a professional-grade cable built for real work. Let us look at the core details. The “4G16” name tells you exactly what it is. “4” means four cores. “G” means it is a flexible stranded wire, not a stiff solid rod. “16” is the size—16 square millimeters of copper. This size is the sweet spot. It is thick enough to carry heavy loads but thin enough to bend around corners. We use 99.9% pure oxygen-free copper. Why? Because copper is the best metal for electricity. It has low resistance. That means less heat and more power at the end of the line. The inside insulation is XLPE (Cross-linked Polyethylene). This is better than standard PVC. It can handle up to 90 degrees Celsius without getting soft. If there is a short circuit, it can handle 250 degrees for a few seconds without burning. The outer sheath is heavy-duty PVC or PE. It is black to block UV light from the sun. This jacket is flame-retardant. If a fire starts, it does not spread the flame. It is also resistant to chemicals. If you spill oil or acid, the cable does not rot.

Where Do You Use This Cable? (Real World Scenarios)
You might ask, “Where exactly does this 4x16mm² wire fit?” The answer is: almost everywhere power is needed.
Industrial Motor Control
This is the most common use. Factories have huge motors for pumps, fans, and conveyors. These motors need three phases of power and a ground wire. That is exactly 4 cores. The 16mm² size is perfect for motors up to 30-40 kW. The XLPE insulation protects the wire from the heat the motor generates. The flexible copper strands handle the vibration of the motor without snapping. If you are building a control panel, use this wire to connect the Variable Frequency Drive (VFD) to the motor. It resists the electromagnetic noise from the drive, so the motor runs smooth.
Main Power Distribution
In a commercial building, you need to move power from the main switchboard to the floor distributors. 16mm² is strong enough to carry the load for a whole floor of offices or apartments. You can run it in the ceiling, in the walls, or in cable trays. If you use the armored version (SWA), you can bury it directly in the ground to feed an outdoor lighting system or a sub-station. The steel armor stops rocks from crushing the copper inside.
Solar and Renewable Energy
The solar industry loves this cable. It is used as the DC cable connecting the solar panels to the inverter, or the AC cable from the inverter to the grid. It is TUV certified for solar use. That means it can sit in the hot sun for 25 years and not crack. It is also double-insulated in some versions to prevent electric shock. If you are doing a 100kW solar project, you need hundreds of meters of this wire. We can supply it in drums of 100m or 1000m.
Harsh Environments
Do you have a project near the sea? The salt air eats normal wires. Our 16mm² cable has a special sheath that blocks moisture and salt. Do you have a project in a mine? The ground moves and rocks fall. The armored version protects against impact. Do you have a project in a cold storage warehouse? The insulation stays flexible even at -20°C. It does not become brittle and crack.

Frequently Asked Questions About 4G16 Cable
Is 16mm² enough for my 100 Amp load?It depends on the voltage and the distance. For 3-phase 400V, 16mm² copper can carry about 80-90 Amps in free air. If you bundle it with other cables or put it in a wall, the current goes down to about 60-70 Amps. Always check with your electrician. If you need more power, we also make 25mm², 35mm², and 50mm².Can I bury this cable directly?Yes, but only if it has armor (SWA or STA). The standard PVC sheath cable is for indoor or conduit use only. If you dig a trench, use the armored version. It is rated for direct burial.What is the difference between XLPE and PVC insulation?PVC is cheaper and good for up to 75°C. XLPE is more expensive but handles 90°C. XLPE is harder and resists water better. For main power and motors, always choose XLPE. For simple lighting, PVC is okay.How do I strip the ends?Use a proper cable stripper. Do not use a knife—you might cut the copper strands. Because the cores are stranded (Class 5), make sure you twist them tight before putting them in the terminal block. Use ferrules if you can.
