The Standard for Safe Elevators: A Simple Guide to 60227 IEC 71F (TVVBG) Cable
You are building a tall apartment block. You are installing a new lift in a shopping mall. The elevator needs to move up and down. It needs power. It needs to be safe.
You have a serious problem. Standard round cables are heavy. They twist. They get stuck in the elevator shaft. Also, if the cable hangs down, it stretches. The copper wires inside can break. This is dangerous.
You need a cable that is safe. You need a cable that follows the rules. You need a cable that is flat and strong.
This is where 60227 IEC 71F (TVVBG) cable comes in.
This name is long. But it is very important. It tells you that the cable is safe. It tells you that the cable is strong. This article is for engineers and buyers. We will break down the name. We will explain why this is the best choice for your building.
Decoding the Name: What is 60227 IEC 71F?
Cable names are like codes. They look hard. But they tell you a story.
Here is the simple translation:
60227 IEC: This is the international rule book. It means the cable is tested. It means the cable is safe. It is a global standard.
71F: This is the specific type of cable. It means it is a flat cable. It is made for elevators.
TVVBG: This is the factory model name. It tells you what is inside.
○
T: Elevator (Lift).
○
V: PVC (Flexible plastic).
○
V: PVC (Outer protection).
○
B: Flat (Not round).
○
G: Steel Wire (Strong core).
In short: This is a certified elevator cable. It is flat. It has a steel core for strength. It is safe to use.
Why Choose This Cable?
You might ask, “Why not use a normal wire?”
Normal wires are not safe for lifts. They are not flat. They do not have a steel core.
60227 IEC 71F (TVVBG) is different.
It is designed for safety and strength.
First, the Steel Core (G). This is the muscle. The steel wire holds the weight of the cable. The copper wires do not have to hold the weight. They just carry electricity. This stops the cable from stretching.
Second, the Flat Shape (B). Round cables twist in the shaft. Flat cables hang straight. They move smoothly. They do not get stuck.
Third, the Certification (IEC). This is the most important part. You know the cable is good. It has passed strict tests. It will not fail you.
Technical Specifications Table
We know you need the hard numbers. Here is a simple table with the specs.
Feature | Specification | Simple Explanation |
Standard | IEC 60227 / GB/T 5023 | International safety rules. |
Model | TVVBG | The factory code for this cable. |
Voltage | 300/500V | Standard elevator voltage. |
Conductor | Stranded Copper | Flexible, Class 5 or 6. |
Core | Steel Wire Rope | The “G” component. Holds the weight. |
Insulation | PVC | Flexible plastic. |
Temperature | -10°C to +70°C | Works in normal building heat. |
Speed | Up to 4 m/s | For fast elevators. |
Where Should You Use It?
This cable is for safe and tall jobs. It is not for small machines.
Here are the best places to use it:
1.
High-Rise Buildings: If the building is over 20 floors, use this. The steel core is needed.
2.
Fast Elevators: If the elevator moves faster than 2 meters per second, use this.
3.
Shopping Malls: Malls have heavy use. This cable is tough.
4.
Hotels: Hotels need safety. This cable is certified (IEC).
5.
Long Travel: If the elevator travels more than 80 meters, this is required.
The Difference Between TVVB and TVVBG
This is a common question. The names are very similar.
TVVB (Standard): This is a basic flat cable. It has no steel core. It is for short elevators (under 80 meters).
TVVBG (With Steel): This has the steel rope. It is for tall elevators. It is strong.
60227 IEC 71F: This is the official name for the TVVBG type. It means it meets the standard.
The Rule of Thumb: If the elevator is short, use TVVB. If the elevator is tall, use TVVBG (60227 IEC 71F).
Installation Tips
This cable is heavy. It is strong. You must install it right.
Use the Clamp: There is a special clamp for the steel core. You must fix the steel core at the top. The copper wires must hang loose. Do not let the copper hold the weight.
Check the Bend: Do not bend the cable too much. The flat shape must be kept.
Temperature: Do not install it if it is freezing (below -10°C). The PVC might crack.
