What is N2xs (SE) Y Cable?
N2xs (SE) Y is a type of power cable. It is used for underground electricity networks. You can also use it in wet or dry places. This cable is very strong. It does not break easily. It is a popular choice in Europe and other markets. The name looks like a code. But it is easy to understand. Each letter tells you something about the cable. It stands for the materials and the standards.
What does the name mean?
The name N2xs (SE) Y follows a German standard (DIN VDE). Let’s break it down into small parts.
The “N” and “2”
“N” means it follows a standard norm. “2” refers to the type of conductor and insulation. It tells us it is a power cable.
The “x” and “s”
“x” stands for XLPE insulation. This is a special plastic. It handles heat very well. “s” means there is a lead sheath. This is a metal layer. It stops water from getting in.
The “(SE)” and “Y”
“(SE)” means a specific type of earth connection. “Y” is the outer jacket. It is usually made of PVC or PE. This protects the cable from dirt and rocks.
Why is this cable special?
This cable has three main benefits. These benefits make it better than old cables.
No Halogen (HFFR)
This is the most important feature. It is halogen-free. If a fire happens, it does not make toxic smoke. It is safe for people in buildings like hospitals or schools. It is also good for the environment.
Fire Resistant
The cable does not burn easily. Even in a fire, it keeps working for a while. This gives people time to fix the problem or leave the area.
Strong Mechanical Protection
It has a metal sheath. This makes it very tough. You can bury it directly in the ground. You do not always need a pipe. This saves money on installation.
Technical Specifications (Data Sheet)
Here are the standard technical details. You can use this to check if the cable fits your project.
| Parameter | Value |
|---|---|
| Standard | DIN VDE 0276-603 / IEC 60502-2 |
| Voltage (Uo/U) | 0.6/1 kV (1.2 kV options available) |
| Conductor | Copper (Cu) or Aluminum (Al) |
| Insulation | XLPE (Cross-linked Polyethylene) |
| Sheath | Lead (Pb) or Aluminum (Al) |
| Outer Jacket | PVC (Purple/Black) or PE (Black) |
| Temperature (Fixed) | -20°C to +70°C |
| Temperature (Emergency) | Up to 90°C (Short circuit: 250°C) |
| Bending Radius | 12x to 15x Cable Diameter |
Voltage Ratings
Most buyers need 0.6/1 kV. This is for standard city power. If you need higher voltage, ask the factory. We can make cables for up to 36 kV.
Conductor Options
Copper is the best for conductivity. It is heavy and costs more. Aluminum is lighter and cheaper. But you need a bigger size for the same power.
Where do you use N2xs (SE) Y?
You can use this cable in many places. It is very flexible for engineers.
Underground Networks
This is the main use. It goes under streets and parks. The lead sheath stops ground water. It also stops chemicals in the soil from damaging the wire.
Industrial Areas
Factories need strong cables. Machines cause vibrations. This cable is thick. It does not shake loose. It is also safe if there is oil or gas around.
Renewable Energy
Solar and wind farms use this cable. It connects the panels to the grid. It can handle outdoor weather for 30 years.
N2xs (SE) Y vs. Other Cables
How is it different from NYY or NAYY? Let’s compare them simply.
Compared to NYY
NYY has PVC insulation. N2xs has XLPE insulation. XLPE handles more heat. N2xs carries more power than NYY of the same size. But N2xs costs more.
Compared to NAYY
NAYY has an aluminum sheath. N2xs often has a lead sheath. Lead is heavier. But lead is softer. It is easier to seal at the ends. Aluminum is lighter but harder to seal perfectly.
How to choose the right size?
Choosing the size is easy if you know the load. The load is the amount of power you need.
Calculate the Amps
First, find out how many amps your machines use. Add them up. Then, look at the cable table. Find the row that matches your amps.
Check the Voltage Drop
If the cable is very long, you lose voltage. This is bad for machines. Pick a size one step bigger if the distance is over 100 meters.
Soil Conditions
If the soil is very hot, the cable cools down slower. You may need a bigger cable. If the soil is wet, it cools better. Tell your supplier about your soil type.
Why buy from a Chinese Factory?
China makes a lot of cables. The quality is good now. The price is better than European brands.
Cost Savings
You save about 30% to 50% on cost. The raw materials like copper are cheaper to buy in bulk here. The labor cost is also lower. But the machines are the same as in Europe.
Fast Production
Chinese factories are fast. We can finish an order in 10 days. European factories might take one month. Speed is important for projects.
Customization
We can change the color. We can change the print on the cable. We can make the jacket UV-resistant. Just tell us what you need.
Quality Control in the Factory
You worry about quality. We have strict tests. We do not send bad cables.
Raw Material Check
We test the copper and XLPE before we start. We make sure it is 99.9% pure copper.
During Production
We check the thickness of the insulation. We use lasers to measure the diameter. If it is too thin, the machine stops.
Final Testing
We test the voltage. We put high voltage on the cable for 15 minutes. If it sparks, we reject it. We also do a bending test. We bend the cable to see if it cracks.
Packing and Shipping
Cables are heavy. We pack them well so they do not get damaged.
Drum Packing
We use wooden drums or steel drums. The cable is wrapped in plastic first. This keeps moisture out during sea shipping.
Container Loading
We load the drums tightly. We use braces so they do not roll. We can put 20 tons in one 20-foot container.
Documents
We give you the Bill of Lading. We give you the Invoice. We give you the Packing List. We also give you the Test Report and Certificate of Origin.
Frequently Asked Questions
Is N2xs (SE) Y armored?
Yes, it has a metal sheath. It acts like armor. It protects against physical damage.
Can I use it in water?
Yes. It is designed for wet places. The outer jacket is waterproof.
What is the minimum order quantity?
It depends on the size. For standard sizes, we might have stock. For special colors, we need 1000 meters.
