The Fire-Safe, Heat-Resistant Wire: A Simple Guide to ZA-RVV-90 Cable
You have a big project. Maybe it is a subway station. Maybe it is a tall office building. Or maybe it is a power plant.
You need to run power cables. But you have two big problems.
First, the place is hot. The wires are near machines or pipes. Normal wires get hard and crack in the heat.
Second, the place is dangerous. If a fire starts, normal wires act like fuel. They help the fire grow. They spread the flame to other rooms.
A normal wire cannot fix these problems. A normal wire melts. A normal wire burns.
You need a wire that handles heat. And you need a wire that fights fire.
This is where ZA-RVV-90 cable comes in.
It is not just a wire. It is a shield. It has a heat shield and a fire shield. This article is for buyers and engineers. We will break down the name. We will explain why this cable is the best choice for high-risk places.
Decoding the Name: What is ZA-RVV-90?
Cable names are like codes. Each letter tells you a secret about the safety and the shape.
Here is the simple translation of ZA-RVV-90:
ZA: This is the fire rating. Z means Flame Retardant. A means Class A. This is the highest level. It stops big fires.
R (Ruan): This means Soft. The copper inside is many thin strands. It is flexible like a rope.
V (PVC): This is the material. It uses PVC plastic for insulation and the outer jacket.
90: This is the heat rating. It means the wire can handle 90°C. Normal wires only handle 70°C.
In short: ZA-RVV-90 is a flexible power wire. It stops the worst fires. And it handles high heat without melting.
Why Choose ZA-RVV-90?
You might ask, “Why not use a normal fire-safe wire?”
A normal fire-safe wire (like ZA-RVV) stops fire. But it cannot handle high heat. If the room gets too hot, the plastic gets hard. It cracks. The power fails.
ZA-RVV-90 is different.
It is designed for maximum safety and heat.
First, the Class A Fire Rating. This is the most important part. “ZA” means it passes the toughest fire test. If you bundle many of these wires and light them, the fire will go out. It will not spread. It protects the whole building.
Second, the 90°C Rating. This is the second key part. The plastic is special. It can handle heat up to 90 degrees Celsius. It stays soft. It does not crack. It is safe near hot machines.
Third, Flexible Copper. The “R” means the copper is soft. It is easy to install. You can bend it around corners.
Technical Specifications Table
We know you need the hard numbers. Here is a simple table with the standard specs for ZA-RVV-90 cable.
Feature | Specification | Simple Explanation |
Standard | IEC 60332 / GB/T 19666 | International safety standards. |
Voltage | 450/750V (0.6/1kV) | Standard voltage for power. |
Conductor | Stranded Copper (Class 5) | Flexible fine wires (like a rope). |
Insulation | PVC (90°C) | Plastic layer that handles heat. |
Jacket | PVC (90°C) | Outer skin that handles heat. |
Flame Test | IEC 60332-3-25 (Cat A) | Stops the biggest fires from spreading. |
Temperature | -15°C to +90°C | Handles higher heat than normal. |
Where Should You Use ZA-RVV-90?
This cable is for critical places. It is not for a simple home lamp. It is for places where fire and heat are big risks.
Here are the best places to use it:
1.
Subways and Tunnels: This is a top use. In a tunnel, fire is very dangerous. There is no way out. ZA cable stops the fire.
2.
High-Rise Buildings: In tall buildings, fire can move fast up the walls. ZA cable helps stop the fire on one floor.
3.
Power Plants: These places have a lot of heat. A fire can be a disaster. ZA-90 cable protects the plant.
4.
Industrial Areas: In a factory, machines get hot. Normal wires crack. This cable handles the heat.
5.
Crowded Places: In a mall or airport, safety is key. This cable is safe for people.
The Difference Between ZA-RVV and ZA-RVV-90
This is a common question. Both cables stop fire. But they are not the same.
ZA-RVV (Normal Fire): This is a safe wire. It stops fire. But it only handles heat up to 70°C.
ZA-RVV-90 (Heat Resistant): This is a stronger wire. It stops fire. And it handles heat up to 90°C.
The Rule of Thumb: If the room is cool, use ZA-RVV. If the room is hot (near machines), use ZA-RVV-90.
Installation Tips for ZA-RVV-90
Even a strong cable needs care. Here are three tips for installing this cable.
Bending: This cable is flexible. But do not bend it too much. The rule is: the bend radius should be at least 6 times the diameter of the cable.
Temperature: Do not install the cable if it is very cold (below -15°C). The plastic might crack.
Cutting: Be careful when you cut the cable. Use a good tool. Do not hurt the inner wires.
