Heat Shrinkable Busbar Insulating Tape
Heat shrinkable busbar insulating tape, also commonly known as insulated copper busbar or electrical busbar, is the core power transmission component that integrates conductivity, insulation, and protection in new energy and power systems. It uses high-purity copper as the conductive substrate and forms a dense and continuous insulation protective layer through the insulation process of PE/PVC heat shrink tubing. It is the key "power vessel" connecting power generation, energy storage, and power supply links.

Product Introduction
Heat shrinkable busbar insulating tape is not just ordinary tape or tubing. It is an active insulation and mechanical protection integrated material designed specifically for copper busbars, connecting bars, and busbars. It undertakes four core tasks in new energy high-voltage systems: insulation enhancement, stress buffering, wear prevention, and identification differentiation. Different from traditional dipping or powder coating processes, heat shrinkable insulation tape can be wrapped twice after the busbar is formed, suitable for on-site modification of irregular, bent, and installed busbars, solving the pain points of flexible protection that cannot be covered by fixed insulation processes.
Product features
Form flexibility
The structure of the Heat shrinkable busbar insulating tape can adapt to complex busbar shapes such as L-shaped and Z-shaped, solving the limitation of traditional sleeve type heat shrink tubing that cannot be bent. It does not require additional cutting or modification of the busbar and is suitable for various irregular installation scenarios, greatly improving construction convenience.
01
High shrinkage rate
After shrinkage, it tightly adheres to the surface of the Customized busbar insulating tube without gaps, with stable insulation performance across complex application environments. It can effectively block the invasion of pollutants such as moisture and dust, eliminate hidden dangers such as creepage and arc breakdown, and ensure the long-term safe operation of the busbar.
02
Color diversity
Solid insulation tubing busbars in standard colors such as red, yellow, green, and black are provided for easy visual identification and daily equipment maintenance. Exclusive colors can be customized according to actual customer engineering needs to clearly distinguish different phase sequences and greatly reduce the error rate of later maintenance and repair work.
03
Environmentally friendly flame retardant
Compliant with UL94-V-0 flame retardant standards, halogen-free, RoHS/REACH certified, no toxic or harmful gases released during combustion, fully meeting global environmental compliance requirements while effectively curbing fire spread and enhancing the overall safety protection level of the power system.

4. Cooling and shaping: Quickly cool and fix the insulation layer to maintain dimensional stability.
Application advantages
New energy vehicles
EV battery connectors inside the battery pack increase energy density, while solving the complex spatial layout problem of L-shaped/Z-type busbars through thin insulation layers (≤ 1.5mm), providing key support for the design of high-energy density battery modules.
Photovoltaic energy storage
The DC side of the inverter is insulated to prevent condensation and flashover, and its UV aging resistance (≥ 1000 hours) ensures long-term stable operation of outdoor equipment in extreme weather conditions, reducing the operation and maintenance costs of the Battery terminal bus bar.
Industrial power distribution
Heat shrinkable busbar insulating tape protection for switchgear reduces cabinet volume by 30%, achieves equipment miniaturization through high insulation strength (3500-5000VDC), and greatly reduces material usage and installation space.
