What is a Flame Retardant Cable?
A flame retardant cable is a special power cable. It looks like a normal cable. But it acts very differently in a fire. When a fire starts, normal cables burn easily. They help the fire grow. They also make a lot of smoke. This smoke is toxic. It hurts people. It damages equipment.
Our flame retardant cable is different. It is made to stop burning when the fire source is gone. We call this “self-extinguishing.” It does not spread the fire to other rooms. It keeps the fire in one place. This gives people time to escape. It also protects other equipment.
We use special materials for the jacket and insulation. These materials are hard to ignite. They do not burn fast. This cable is for safety. It is for places where fire risk is high. Like hospitals, schools, and subways.
How Does It Work?
The secret is in the chemical formula. We use specific compounds in the PVC or XLPE. These chemicals react when they get hot. They release water vapor. This cools the cable down. It also forms a char layer on the surface. This char is like a shield. It stops oxygen from reaching the inner wire. Without oxygen, the fire dies.
There are different levels of performance. Some cables only stop flame for a short time. Others stop flame and reduce smoke. We focus on “Low Smoke Zero Halogen” (LSZH). This means if it burns, there is very little smoke. And there is no acid gas. Acid gas is very dangerous. It destroys lungs and electronics. Our cable is safe for indoor air.
Key Technical Specifications
Here are the hard numbers. These are the details engineers need. You can use this for your project specs.
Conductor Material
We use high-purity electrolytic copper. It is 99.9% pure. This gives the best conductivity. We can also make it with Copper Clad Aluminum (CCA) if you need to save money. But copper is better for safety. The conductor is solid or stranded. Stranded is more flexible. It is easier to pull through pipes.
Insulation Material
We use Cross-linked Polyethylene (XLPE). It is better than PVC. XLPE can handle higher heat. It does not melt easily. The maximum operating temperature is 90°C. In a short circuit, it can go up to 250°C. It is very tough against chemicals and moisture.
Sheath / Jacket Material
The outer skin is special Flame Retardant PVC or LSZH compound. The color is usually orange or red. Orange is standard for fire-resistant cables. We can print on the jacket. We print the brand, voltage, and size every meter. This helps you check the cable easily.
Voltage Ratings
We make Low Voltage (LV) cables.
- 0.6/1kV: This is the most common. Used for general power.
- 1.8/3kV: Used for slightly higher power needs.
- 3.6/6kV and higher: We can do medium voltage too. Ask us for details.
Fire Test Standards
Our cables pass strict global tests.
- IEC 60332-1: This tests a single vertical cable. It must self-extinguish.
- IEC 60332-3: This tests a bunch of cables together. It simulates a real cable tray fire.
- BS 4066: This is a British standard. It is very tough.
- UL 1581 / UL 1685: These are for North America. We do the “Vertical Tray Test.”
Why Choose Our Flame Retardant Cables?
Safety First
Fire kills. Smoke kills. Our cable saves lives. It limits the fire area. It buys time for firefighters. It reduces toxic gas. This is the top reason to buy from us. You are selling safety to your clients.
Long Service Life
Moisture and heat destroy normal cables fast. Our XLPE insulation resists water. You can bury it in the ground. You can put it in wet ducts. It lasts 30 years or more. This saves maintenance cost.
Easy to Install
The cable is flexible. It bends easily around corners. You do not need special tools to strip it. The outer skin is strong. It resists scratches during pulling. This makes your electricians work faster.
Cost Effective
We are a factory. We control the raw material cost. We buy copper in bulk. Our production line is fast. We give you a factory price. It is cheaper than big brands but has the same quality. We offer OEM. We put your logo on the package.
Where to Use These Cables?
You can sell this cable for many projects. Here are the best markets:
Commercial Buildings
Skyscrapers need this. Office blocks have thousands of people. Fire codes are strict. Use our cable for lighting, power sockets, and fire alarms. It meets the building inspector’s requirements.
Public Transport
Subways, trains, and airports are high risk. Tunnels are hard to escape. Cables must not burn. They must not smoke. Our LSZH cable is perfect for the train carriage and the station platform.
Industrial Factories
Factories have heavy machines. They use high power. They have oil and chemicals. Our cable resists oil. It is safe for the control panels. It keeps the production line running safely.
Data Centers
Servers cost millions. Smoke destroys servers. Halogen gas corrodes the metal contacts. Our Zero Halogen cable protects the data. It is safe for the server room environment.
Frequently Asked Questions (FAQ)
What is the difference between FR and NH cable?
FR means Flame Retardant. It stops burning when fire is removed. NH means Fire Resistant (Nai Huo). NH cable can keep working even inside a fire for a time (like 90 minutes). It is for emergency lights. We make both.
Can you supply the test reports?
Yes. We have reports for IEC, BS, and ASTM. We can send you the PDF by email. We also accept third-party testing. You can send SGS or Intertek to our factory.
What is the minimum order quantity (MOQ)?
For standard sizes, we have stock. MOQ can be 500 meters or 1000 meters. For special colors or prints, MOQ is higher. It depends on the material waste. Contact us for the exact number.
How do you pack the cable?
We use wooden drums or steel-wood drums. The drum is fumigated. This is safe for shipping. The cable is wrapped with plastic film. It is water-proof. We also put warning tape on the side: “FRAGILE – CABLE”.
What is your lead time?
Standard orders take 7 to 10 days. Big orders (containers) take 15 to 20 days. We ship by sea or air. We can do DDP terms. We handle the customs clearance for you.
How to Order?
Buying from us is simple. Send us your inquiry. Tell us the voltage, size (like 3×2.5mm), and quantity. We calculate the price fast. We provide free samples. The sample is 10 meters long. You test it in your lab. If it passes, you place the big order. We are your reliable partner in China. We care about quality. We care about your reputation. Let’s build a safe world together.
