In power equipment and transmission and distribution systems, busbars are core components for power transmission and distribution, and their insulation protection is crucial. Inadequate insulation can not only lead to safety hazards such as equipment short circuits and leakage, but can also affect the stable operation of the entire power system. Therefore, busbar heat shrink tubing, a high-performance insulation protection product, is increasingly becoming a preferred insulation solution for medium- and low-voltage switchgear and indoor busbars.

What is busbar heat shrink tubing?


 
 
Busbar heat shrink tubing is a high-performance heat-shrinkable insulating tubing made of radiation-cross-linked polyolefin. By heating, it tightly wraps around the busbar or connector surface, forming a uniform, strong insulating layer. It not only provides excellent electrical insulation performance but also effectively protects against mechanical wear, chemical corrosion, and carbon marking in complex environments, significantly enhancing equipment reliability and lifespan.
 
Why choose Volsun busbar heat shrink tubing?
 
1. Excellent Physical, Chemical, and Electrical Properties
 
Volsun busbar heat shrink tubing maintains stable performance within a temperature range of -55°C to 125°C, making it suitable for both extremely cold and hot environments and resistant to aging and cracking. Its strong resistance to electrical carbon tracking prevents the formation of conductive paths even in humid and dirty environments, effectively eliminating creepage.
 
2. Significantly Reduces Phase Spacing and Optimizes Equipment Layout
 
With excellent dielectric strength and a 2:1 heat shrink ratio, busbar heat shrink tubing reduces phase spacing while ensuring insulation safety, enabling more compact equipment designs. It is particularly suitable for space-constrained switchgear and distribution boxes.
 
3. Easy Installation and Strong Adhesion
 
It shrinks rapidly at temperatures between 70°C and 120°C, ensuring efficient installation without the need for complex equipment. After shrinking, it tightly wraps the busbar, eliminating bubbles and wrinkles, and provides a perfect fit even in irregular shapes.
 
4. Available in a variety of sizes and colors
 
Our busbar heat shrink tubing complies with RoHS directives and is available in three voltage levels: 1kV, 10kV, and 35kV, meeting the needs of diverse electrical environments. The standard colors are red, yellow, and green, clearly distinguishing the three phases, and custom colors are available for easier management.

 
Busbar heat shrink tubing has a wide range of applications, whether in new power projects or retrofits of existing equipment. For example:
 

• Insulation protection of busbars and contacts in medium and low voltage switchgear;
• Internal insulation treatment of transformers, distribution boxes, ring main units, and other equipment;
• Power supply systems in rail transit, new energy power plants, industrial automation, and other fields;
• Local insulation reinforcement and restoration in substations and power maintenance.
