What is WDZAN-RYS Cable? A Simple Guide for Importers
If you work in construction or electrical trade, you know safety is the top priority. You need wires that work well. You also need wires that keep people safe. Today, we talk about a special cable. It is called WDZAN-RYS. This name sounds long and confusing. But it is actually simple. It is a type of power cable. It is used in buildings. It stops fire. It saves lives. Let’s learn more about it.
What does WDZAN-RYS mean?
The name is a code. Each letter tells you something about the cable.
W: Low Smoke
W stands for “Low Smoke.” Normal cables make a lot of black smoke when they burn. You cannot see anything. It is hard to escape. WDZAN-RYS makes very little smoke. The air stays clearer. You can see the way out.
D: Low Halogen
D stands for “Low Halogen.” Halogen is a chemical. Most cables have it. When it burns, it makes toxic gas. This gas hurts your lungs. It is very dangerous. WDZAN-RYS has almost no halogen. It is safe to breathe near it.
Z: Flame Retardant
Z means “Flame Retardant.” This cable does not catch fire easily. If a fire starts, the cable stops the fire from spreading. It is like a wall against flames.
A: Class A Fire Resistance
A is for “Class A.” This is a high level. It means the cable can handle very high heat. It keeps working even in a big fire.
N: Fire Resistant
N means “Fire Resistant.” It is similar to A. But it focuses on time. The cable works for a long time while burning. Usually, it is 90 minutes. Or it is 120 minutes. This gives people time to leave.
RYS: Soft Copper Wire
RYS describes the inside. It has soft copper wires. They are flexible. They are easy to install in tight pipes. They do not break easily.
Why is this cable popular?
This cable is famous for one reason: safety. Modern buildings are tall. They have many people inside. If a fire starts, it is scary. You need cables that do not add to the danger. WDZAN-RYS does not burn fast. It does not make poison gas. Builders love it. Architects specify it. It is the standard for hospitals, schools, and malls.
Another reason is the law. Many countries have strict rules. They say you must use safe cables in public places. WDZAN-RYS meets these rules. If you import cables, you need to know these rules. Selling this cable opens big markets for you.
How is it different from normal cables?
Let’s compare it with a standard cable, like BV or VV.
Material difference
Normal cables use PVC plastic. It is cheap. But it burns fast. It makes black smoke. WDZAN-RYS uses special rubber or XLPE. This material is strong. It does not melt easily.
Safety difference
Imagine a fire in a hotel.
- Normal cable: Burns quickly. Releases acid gas. People get hurt. The fire spreads to other rooms.
- WDZAN-RYS: Burns slowly. Releases water and CO2 mostly. The fire stays in one place. People can escape.
Price difference
WDZAN-RYS costs more. The materials are expensive. The making process is hard. But it is worth it. You pay for safety. You do not want a cheap cable to cause a disaster.
Technical Specifications Table
Here is the data sheet. We use simple terms. You can show this to your engineers.
| Feature | Detail | What it means for you |
|---|---|---|
| Standard | IEC 60332 / GB/T 19666 | It follows global safety rules. |
| Voltage Rating | 450/750V / 0.6/1kV | Good for normal building power. |
| Conductor | Soft Copper (Class 5) | Very flexible. Easy to pull. |
| Insulation | XLPE / LSZH | High heat resistance. No toxic smoke. |
| Sheath | LSZH (Low Smoke Zero Halogen) | The outer skin is safe and fireproof. |
| Fire Test | IEC 60331 / IEC 60332 | It passes the wire flame test. |
| Operating Temp | -15°C to 70°C (or 90°C) | Works in hot and cold weather. |
| Bending Radius | 6x or 12x Diameter | You can bend it without breaking. |
| Application | High-rise buildings, Subways, Airports | Best for big projects. |
| Certificates | CE, CCC, ISO, SGS | You need these to clear customs. |
Where do you use WDZAN-RYS?
You cannot use this cable everywhere. It is too expensive for a small home light. You use it where the risk is high.
Emergency Systems
Fire alarms need power to work. Emergency lights need power. If the main power cuts, this cable keeps the lights on. It helps people find the exit.
Public Transport
Subways and trains use a lot of power. They are underground. Smoke is deadly underground. WDZAN-RYS is mandatory here. It keeps the train running if a fire starts.
Commercial Buildings
Hospitals have sick people. They cannot run fast. Schools have kids. Malls have crowds. These places must use WDZAN-RYS. It is the responsible choice.
How to buy the right WDZAN-RYS?
If you are an importer, you must be careful. Not all factories make good cables.
Check the Copper
Copper is expensive. Some bad sellers mix aluminum with copper. Aluminum breaks easily. It gets hot. Always ask for 99.9% pure copper. Ask for the Class 5 flexibility standard.
Check the Sheath Material
Ask for a sample of the plastic. Burn it with a lighter. If it goes out when you remove the fire, it is good. If it keeps burning and drips, it is bad PVC. Real LSZH is hard to burn.
Check the Certificates
Do not trust words only. Ask for test reports. Look for CE or UL marks. If the factory says it meets IEC standards, ask for the IEC report number. Verify it on the official website.
Ask for the “A” Class
There are Class A, B, and C. Class A is the best. It handles the highest heat. Always ask for Class A for your high-rise projects. Class C might be too weak for big fires.
Common questions about this cable
Is it waterproof?
Not really. The “W” is for smoke, not water. If you need it wet, you need a special armor or black PE sheath. Ask the factory for “Waterproof LSZH” if you need it outside.
Can I use it for solar panels?
Sometimes. But solar cables usually have different insulation (EN 50618). WDZAN-RYS is better for the connection from the inverter to the grid inside the building.
Why is it so heavy?
Copper is heavy. The fire-proof material is thick. A good cable feels heavy. If it feels too light, the copper might be thin. Check the weight per meter. Compare it with the spec sheet.
Conclusion
WDZAN-RYS is not just a wire. It is a safety tool. The world is getting stricter about fire safety. The demand for this cable is growing fast. As an importer, you have a great chance.
Focus on quality. Do not buy the cheapest option. Find a factory that tests every batch. Sell the safety, not just the copper. If you do this, your customers will trust you. They will come back for more.
