Product Introduction
Heat shrink tubing insulated busbar is a high-performance electrical component where conductive copper/aluminum bars are permanently encapsulated with heat-activated polymer sleeves. When heated, the tubing shrinks tightly to form a moisture-proof, corrosion-resistant insulation layer, providing superior electrical protection in compact spaces. This solution is essential for power distribution systems requiring reliable insulation and space efficiency.
working principle
The heat shrink tubing insulated busbar works by applying controlled heat to specially engineered polymer sleeves, causing them to shrink radially and conform tightly to the busbar surface. This creates a seamless, void-free insulation layer through molecular cross-linking, which enhances dielectric strength while providing environmental sealing against moisture, chemicals, and mechanical abrasion.
Product production process
1.Heat shrink tubing busbar production begins with precision stamping of copper sheets to form conductive busbars, followed by ultrasonic cleaning to remove oils and oxides for optimal adhesion.
2.The busbar sleeves insulation process involves sliding pre-cut radiation-crosslinked polymer tubes over the cleaned busbars, with special attention to corner protection and overlap ratios.
3.In heat shrink sleeves busbar final processing, the assemblies pass through multi-stage heating tunnels (150-200°C) where tubes shrink uniformly to form mechanical locking with the busbar surface.
