Why Do Copper Bars Need To Be Covered With Heat Shrink Tubing? What Are The Benefits?

Jan 10, 2025

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.

What are the uses of heat shrinkable sleeves covering copper busbars?

 

1. Enhance heat dissipation and reduce temperature rise;

2. Reduce water vapor and avoid electrochemical corrosion of copper rows;

3. Heat Shrink Tubing BusBar effectively improves 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.

 

Copper busbars are easily corroded by oxidation when exposed to wind and rain for a long time, affecting power transmission capabilities. Copper busbars 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 interfere easily. Causes short circuit, and Heat Shrink Tube Polyolefin Busbar acts as insulation protection, which can effectively avoid such accidents.

 

Busbar Insulation Sheet has a certain thickness and is not afraid of heating. It is suitable for high current places. Covering the copper bar can prevent the copper bar from being interfered by outside air and rain. Even if the copper bar heats up, there is no need to worry.

Now Xiamen Apollo Stamping Welding Technology Co., LTD teaches you how to choose the appropriate specifications and sizes of heat shrink tubing.

 

Heat Shrink Tubing The specifications of the BusBar 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 straight The diameter is about 70.06, and the heat shrinkable sleeve is covered on the copper bar, so it is generally necessary to choose a heat shrinkable sleeve with a diameter greater than 70mm. Petrogolin recommends a heat shrinkable sleeve with a diameter of 80 or 90mm. If the heat shrinkable sleeve is too large, first of all, the size does not match, and secondly, it is easy to burn due to too long heating time.

 

Xiamen Apollo Stamping Welding Technology Co., LTD supports customized extruded copper busbars, dipped copper busbars, thermoplastic sleeve copper busbars, laminated soft copper busbars, aluminum busbars, copper-aluminum composite busbars, etc. The sample material is T2 copper conductor + PVC insulation.
