Heat Shrink Tubing BusBar: An Efficient Insulation Solution For The New Energy Industry
Jun 18, 2025
Heat Shrink Tubing BusBar is a type of copper busbar insulated with heat shrink tubing, widely used in new energy vehicles, energy storage systems, and power electronics equipment. By utilizing the properties of heat shrink tubing, which contracts upon heating to closely fit the surface of the busbar, a uniform and robust insulating layer is formed. This layer effectively prevents short circuits, oxidation, and corrosion, while enhancing the safety and reliability of electrical systems.

Material Characteristics
The primary insulating material for Heat Shrink Tubing BusBar is polyolefin heat shrink tubing. This material has excellent electrical insulation properties and mechanical strength. Polyolefin heat shrink tubing contracts at high temperatures to form a tight insulating layer, with an insulation strength of up to 20kV/mm and a withstand voltage of 5000V. Additionally, this material features good heat resistance, operating stably within a temperature range of -40℃ to 125℃. It also has excellent chemical corrosion resistance and flame retardancy.

Production Process
The production process of PE Heat Shrink Tube Insulated Busbar includes several key steps:
| Busbar Fabrication | Copper materials are processed into the desired shapes and sizes according to customer requirements. |
| Selection and Pretreatment | Suitable polyolefin heat shrink tubing is selected and cleaned to ensure the quality of the insulating layer. |
| Tubing Installation | The heat shrink tubing is placed over the busbar surface, ensuring complete coverage of the insulation area. |
| Heating and Shrinking | The heat shrink tubing is heated using a heat gun or oven, causing it to contract and tightly fit the busbar surface, forming a uniform insulating layer. |
| Quality Inspection | Rigorous electrical and mechanical performance tests are conducted on the finished products to ensure compliance with international standards. |
