The Function Of Covering The PVC Insulation Busbar With Heat Shrink Tube

Busbar insulating tubing, also known as heat shrink tubing, is commonly used in many different applications for components such as wire harnesses and cables. Complete heat shrink tubing is ideal for wire, cable and busbar protection. The heat shrinkable sleeve protects the copper bar and the entire working environment to ensure safe and stable operation.

Copper busbars generally need to choose heat shrinkable sleeves of different colors. The main function is to distinguish the positive and negative wiring and provide insulation protection. From the aspects of process, assembly and cost, covering the heat shrinkable sleeve can increase the cost, especially when the main circuit copper bar is designed with multiple copper bar overlap points. In order to improve the assembly efficiency, it is recommended to remove the heat shrinkable sleeve at the overlap. 

The main uses of heat shrinkable sleeves covering copper busbars are as follows:
1. Enhance heat dissipation and reduce temperature rise;
2. Reduce water vapor and avoid electrochemical corrosion of copper rows;
3. The busbar covered with heat shrinkable sleeves can effectively improve the insulation capability;
4. For occasions where it is inconvenient to cover heat shrinkable sleeves, choose to use black paint to cover the copper bars, but use phase sequence color labels to mark the properties of the conductors.

Heat shrink tubing busbars are easily corroded by oxidation when exposed to wind and rain for a long time, affecting power transmission capabilities. They are often used in high-voltage places such as high-voltage distribution cabinets and substations. In this case, small animals or other foreign objects may easily interfere. This can lead to a short circuit, and the products covered with heat shrink sleeves provide insulation protection, which can effectively avoid such accidents. The heat shrinkable sleeve has a certain thickness and is not afraid of heating. It is suitable for high current places. Covering can prevent the copper bar from being interfered by outside air and rain. Even if the product heats up, there is no need to worry.

Now Xiamen Apollo Stamping Welding Technology Co., Ltd will show you how to choose the appropriate specifications and sizes of heat shrinkable sleeves.

The specifications of the heat shrinkable sleeve are related to the size of the copper bar. For example, a copper bar with a size of 100*10 refers to a cross-sectional length of 100 and a thickness of 10. Then we can calculate the perimeter of the copper bar as (100+10)* 2=220, the heat shrinkable sleeve is round, then divide 220 by 3.14 to get the diameter It is about 70.06, and the heat shrink sleeve is covered on the copper bar, so it is generally necessary to choose a heat shrink sleeve with a diameter greater than 70. We recommend a heat shrink sleeve with a diameter of 80 or 90. The heat shrink sleeve If the tube is too large, first of all, the size does not match, and secondly, it is easy to burn due to too long heating time.
