Tired of cables that melt, crack, or fail when the heat turns up?
You know the struggle. You install a cable in a hot environment—maybe a bakery oven, a steel mill, or a heating system. A few months later, the insulation gets brittle. It cracks. Then comes the short circuit, the downtime, and the expensive replacement. Standard PVC cables just can’t handle extreme heat. They melt at 70°C or 90°C. But your machines run much hotter than that.You need a wire that laughs at high temperatures. You need a wire that stays flexible even when it’s freezing cold. You need the German Cable HEAT 180 SiHF 2-core 1 sq mm high-temperature heating wire. This isn’t just a cable. It is a heavy-duty solution built for the toughest industrial jobs. It is imported directly from Germany, ensuring top-tier quality and precision engineering. Let’s look at why this specific cable solves your biggest headaches.
Unbeatable Temperature Range: -50°C to +180°C
Most cables have a small comfort zone. This one has a massive range. The ÖLFLEX® HEAT 180 SiHF works perfectly in freezing cold storage down to -50°C. It also handles scorching heat up to +180°C.Why does this matter?
- No Cooling Period Needed: You can install it near hot machinery without waiting for the machine to cool down.
- Rapid Heat Spikes: If your oven temperature spikes suddenly, this cable won’t melt.
- Winter Ready: If you have outdoor installations in freezing winters, the jacket won’t crack or shatter.
It passes the FT1 vertical flame test. This means if a fire starts, the cable doesn’t spread the flames easily. It is self-extinguishing. For a high-temperature heating wire, safety is just as important as performance.
Superior Materials: Silicone Rubber and Tinned Copper
Cheap cables use copper that rusts or insulation that gets sticky. This German cable uses premium materials.The Conductor:The core is made of finely stranded tinned copper. Why tinned? Because tin stops copper from oxidizing. Oxidation creates resistance and heat. Tinned copper keeps the electrical flow smooth. The stranding is Class 5, which means the wires inside are super thin and twisted together. This makes the cable incredibly flexible. You can pull it through tight conduits without breaking it.The Insulation and Jacket:Both the inner insulation and the outer jacket are made of high-quality silicone rubber. Silicone is naturally heat-resistant. It doesn’t release toxic smoke when burned. It is halogen-free. This is critical for indoor use, public buildings, and food processing plants. If there is a fire, your team isn’t breathing toxic gas.The outer jacket is red-brown. It resists oils, alcohols, and even animal fats. If you work in a food processing plant or a chemical factory, spills won’t eat through the cable.
Technical Specifications for the 2-Core 1.0mm² Model
Here are the exact numbers for the specific model you are looking at. This is the imported cable part number 0046007.
- Part Number: 0046007 (LAPP KABEL)
- Conductor Count: 2 Cores (plus ground connection option in other variants)
- Cross-Section: 1.0 mm² (approx 18 AWG)
- Nominal Outer Diameter: 6.6 mm
- Copper Weight: 19.2 kg/km
- Total Weight: Approx 66 kg/km
- Voltage Rating: 300/500V (Test Voltage: 2000V)
- Minimum Bend Radius: 4 times the cable diameter (approx 26mm). Do not bend it sharper than this, or you damage the internal structure.
- Temperature Range: Fixed installation: -50°C to +180°C. Occasional movement: -25°C to +180°C.
- Color Code: Black with white numbers (for cores) plus green/yellow for ground.

These specs show this is a robust wire. It isn’t flimsy. The copper is thick enough to carry power without overheating. The walls are thick enough to protect against physical damage.
Real-World Applications: Where This Cable Shines
You might ask, “Where exactly do I use this?” The answer is: anywhere it gets hot or messy.1. Foundries and Steel MillsMolten metal creates intense radiant heat. Standard cables turn to ash here. The HEAT 180 SiHF survives. It is used for control circuits in furnaces and casting lines.2. Glass and Ceramic FactoriesKilns run 24/7. The cable needs to handle constant high heat. This silicone cable is perfect for lighting systems and sensors inside the kiln area.3. Commercial Baking and Food ProcessingIndustrial ovens get very hot. Also, wash-down procedures are common. This cable resists steam and hot water. It is also compliant with food safety standards because it doesn’t drip harmful chemicals.4. Heating Elements and VentilationIf you are building a heater, you need a German Cable that can act as a power feed. It handles the high current going to the heating element. It is also great for ventilation engineering where fans move hot air.5. Wind Power and SolarOutdoor installations face UV rays, rain, and heat from the inverter. The UV-resistant and water-resistant nature of the jacket makes it perfect for renewable energy systems.
Why Choose Imported German Quality?
You can buy cheap local cable. But you get what you pay for. German engineering focuses on longevity. The LAPP KABEL factory (the maker of ÖLFLEX®) has strict quality control.
- Consistency: Every meter of cable meets the exact same standard. No weak spots.
- Purity: The silicone used is high-purity. Cheap cables use fillers that reduce performance.
- Testing: Each batch is tested for voltage resistance and heat aging.
When you buy this HEAT 180 SiHF 2-core 1 sq mm wire, you are buying peace of mind. You won’t have to replace it next year. It is a “fit and forget” solution. The fine stranding means it handles vibration well. If your machines shake or move, solid wires break. Stranded wires flex. This cable is built for motion.
Installation Tips for Maximum Life
Even the best cable fails if installed wrong. Here is how to get the best results:
- Respect the Bend Radius: Don’t kink the cable. Keep the bend radius at least 4x the diameter (about 26mm). If you bend it too sharp, you cut the silicone insulation internally.
- Use Proper Terminals: Since the conductors are finely stranded, use ferrules (bootlace ferrules) when connecting to screw terminals. This stops the wires from fraying.
- Separation: Keep this cable away from sharp edges. Even silicone can be cut by a sharp metal burr. Use grommets if passing through metal sheets.
- Shielding: If you have a lot of electrical noise (like near a big motor), look for the shielded version (HEAT 180 C SiHF). It has a copper braid that stops interference. The standard version (unshielded) is fine for most heating and power jobs.
Competitive Advantage: Oil and Chemical Resistance
One of the biggest pain points in industrial plants is oil leaks. Hydraulic oil destroys PVC jackets. It makes them swell and fall off.The HEAT 180 SiHF is different. The silicone jacket is chemically inert. It doesn’t react with:
- Mineral oils
- Hydraulic fluids
- Alcohols
- Cleaning agents
If you are in an automotive plant or a chemical processing plant, this is a huge benefit. You don’t need to run extra conduit to protect the cable from drips. The cable protects itself. This saves you money on installation materials and labor time.
