The Heavy-Duty Solution for High-Rise Elevators: A Simple Guide to TVVBG Cable
You are working on a big project. It is a tall hotel. It is a large office building. You need to install a fast elevator. The lift goes up many floors. It moves very fast.
You have a serious problem. The building is tall. The cable has to hang down a long way.
Usually, you use a standard flat cable. But standard cables are weak. They rely on the copper wires to hold the weight. If the building is too tall, the cable stretches. The copper wires snap. The elevator stops working.
You need a stronger cable. You need a cable that has a muscle. You need a cable that can hold its own weight.
This is where TVVBG cable comes in.
It is not just a wire. It is a heavy-duty tool. It has a steel core. It carries power. It carries signals. And it does not stretch. This article is for engineers and buyers. We will break down the name. We will explain why this cable is the hero of tall buildings.
Decoding the Name: What is TVVBG?
Cable names are like codes. Each letter tells you a secret about what is inside.
Here is the simple translation:
T: This stands for Elevator. It is made for lifts.
V: This is PVC. It is the plastic insulation. It is flexible.
V: This is the Outer Sheath. It is also PVC. It protects the cable.
B: This means Flat. The cable is flat, not round.
G: This means Steel Wire. There is a steel rope inside to hold the weight.
In short: This is a flat elevator cable. It has a steel core for strength. It is built for long distances and tall buildings.
Why Choose This Cable?
You might ask, “Why not use a standard cable?”
Standard cables are okay for small houses. But for tall buildings, they are bad. The copper is soft. It stretches like a rubber band. When it stretches, it breaks.
TVVBG is different.
It is designed for height and strength.
First, the Steel Core (G). This is the most important part. The steel wire takes 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). This saves space. The cable is thin and wide. It fits in small spaces. It does not twist. It hangs straight. It is easy to tie down.
Third, the Flexible PVC (V). Elevators move up and down. The cable bends a lot. Our PVC is soft. It bends easily. It does not crack. It lasts a long time.

Where Should You Use It?
This cable is for specific jobs. It is not for small houses.
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.
Long Travel: If the elevator travels more than 80 meters, this is required.
4.
Shopping Malls: Malls have big lifts. They need strong cables.
5.
Hospitals: Hospitals have large elevators for beds. They need reliable cables.
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 lifts. The copper holds the weight.
TVVBG (With Steel): This has a steel core. It is for tall lifts. The steel holds the weight.
The Rule of Thumb: If the elevator is short (under 80 meters), use TVVB. If the elevator is tall (over 80 meters), use TVVBG.
Installation Tips
This cable is heavy. It is complex. 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 -15°C). The PVC might crack.
