What is NA2XSH Cable?
NA2XSH is a type of power cable. It is very popular in Europe and other international markets. The name looks like a code. Let me break it down for you. “NA” means it follows a specific standard. “2X” refers to the double insulation layer. “SH” means it is safe and resistant to heat and moisture.
This cable is not a standard PVC cable. PVC cables melt easily in fire. NA2XSH is different. It uses special materials. The insulation is cross-linked polyethylene (XLPE). The outer sheath is also special. It does not release toxic smoke. This makes it very safe for buildings, subways, and factories.
Many engineers choose this cable for big projects. It carries high voltage. It is strong. It lasts a long time. If you are a buyer, you need to know these basics. It is a high-quality product. It meets strict safety rules.
Why Choose NA2XSH Over Standard Cables?
You might ask, “Why not use cheaper cables?” The answer is safety and durability. Standard PVC cables have limits. They get soft at 70°C. NA2XSH can handle up to 90°C. This is a big difference.
Here are the main benefits:
Fire Resistance
This cable does not burn easily. If there is a fire, it stops the fire from spreading. It is flame retardant.
No Toxic Gas
When PVC burns, it creates black smoke. This smoke is poisonous. NA2XSH is halogen-free. It releases very little smoke. It is safe for people inside the building.
Moisture Protection
The “H” in the name stands for moisture resistance. You can put this cable underground. You can put it in wet areas. Water does not damage the copper core easily.
Mechanical Strength
The cable has a tough armor. You do not need a separate pipe for it in some cases. It resists pressure. It is good for direct burial in the ground.
Key Technical Specifications
Buyers need exact numbers. Here is the standard data for NA2XSH cables. We follow IEC 60502 and EN 50266 standards.
| Parameter | Value |
|---|---|
| Standard | IEC 60502-2 / EN 50266-2-2 |
| Voltage Rating (U0/U) | 0.6/1 kV to 1.8/3 kV |
| Conductor Material | Copper (Class 1 or 2) |
| Insulation Material | XLPE (Cross-linked Polyethylene) |
| Sheath Material | PVC or PE (Halogen-free option available) |
| Max Operating Temp | 90°C (Normal) / 250°C (Short circuit) |
| Min Operating Temp | -50°C |
| Flame Test | IEC 60332-1 (Pass) |
| Halogen Content | Low / Zero (LSZH) |
You can see the voltage range is wide. It works for both low and medium power networks. The conductor is always copper. We do not use aluminum for this grade. Copper conducts electricity better. It lasts longer.
The insulation is the key part. XLPE is better than PVC. It handles heat well. The sheath protects the cable from the outside world. You can choose PVC for low cost. You can choose LSZH (Low Smoke Zero Halogen) for high safety. LSZH is more expensive but required in airports and hospitals.
Where to Use NA2XSH Cable?
This cable is versatile. You can use it in many places. Here are the top three uses.
Underground Networks
This is the most common use. Cities need power under the street. NA2XSH is strong. It can handle soil pressure. It resists water. You can bury it directly without a concrete pipe. This saves money on installation.
Industrial Factories
Factories use heavy machines. They need a lot of power. The cables get hot. NA2XSH handles the heat. It is also safe in chemical plants. The outer sheath resists oil and chemicals.
High-Rise Buildings
Safety is key here. If a fire starts, you want low smoke. NA2XSH keeps the stairs clear of smoke. It helps people escape. It also keeps the power on for fire alarms longer.
Renewable Energy
Solar and wind farms use this cable. It connects the panels to the grid. It works outside in the sun and rain for 30 years. It is very durable against UV rays.
How to Order NA2XSH from China?
China makes the best cables. We are a factory. We can make the cable exactly how you want it. Here is the process.
Step 1: Define the Voltage
Tell us the voltage you need. Is it 1kV? Or 3kV? The insulation thickness changes with voltage.
Step 2: Choose the Armor
Do you need steel wire armor? Or steel tape? SWA (Steel Wire Armor) is for rough ground. STA (Steel Tape Armor) is for general use.
Step 3: Sheath Color
Black is standard. But you can order red, blue, or yellow. It helps workers identify the cables.
Step 4: Length and Packaging
We usually pack in drums. A standard drum is 500 meters or 1000 meters. We can also do wooden pallets.
Step 5: Testing
Ask for test reports. We do voltage tests. We check the conductor resistance. We ensure the cable meets the standard before shipping.
Common Mistakes to Avoid
Buyers often make errors. Here is how to avoid them.
Buying PVC Instead of XLPE
Some sellers sell cheap PVC cables as NA2XSH. Always check the data sheet. Look for “XLPE” or “Sioplas” insulation. PVC is cheaper but risks fire safety.
Wrong Voltage Rating
Do not use a 1kV cable for a 3kV system. It will explode. Always check the system voltage first.
Ignoring the Armor
If you bury the cable without armor, rats might eat it. Or rocks might cut it. Always use armored cable for underground.
Cheap Copper
Some factories use recycled copper. It breaks easily. It has high resistance. Ask for pure electrolytic copper. It costs a bit more but works better.
Frequently Asked Questions
Is NA2XSH cable waterproof?
Yes. It is designed for wet places. But the joints must be sealed well. Water gets in through the ends, not the side.
Can I use it in -20°C weather?
Yes. It works down to -50°C. It is great for cold countries like Russia or Canada.
What is the difference between NA2XSH and NAYY?
NAYY has PVC insulation. NA2XSH has XLPE insulation. NA2XSH handles more heat. NAYY is cheaper for low-heat areas.
How long does it last?
Usually 30 to 50 years. It depends on the soil and heat. XLPE does not rot like PVC.
Do you provide samples?
Yes. We can send a short sample. You can test it in your lab. We pay for the quality.
