800V Busbar Heat-Shrink Tubing for High-Voltage Platforms
Rated wall and recovery for 800V EV and energy-storage busbars. 800V platforms need insulation that holds wall after recovery and resists tracking under humidity. We build the sleeve with a voltage-rated wall and V-0 behavior for the 800V duty. We match shrink ratio, recovered wall and color to your busbar stack and assembly process.

Applications by industry
- 800V EV and hybrid battery busbar phase insulation
- Inverter-to-motor HV cable busbar protection
- ESS pack DC busbar sleeve insulation
- High-voltage junction box busbar covering
- Automotive traction busbar creepage management
- Heat-shrink phase separation on 800V DC busbars
Why crosslinked polyolefin / EPDM for this application
At 800V DC the creepage and partial-discharge margins are tight, so the sleeve must be crosslinked, sized to the bar and thin to clear tight pack geometry while fully isolating the conductor edges.
p>Confirm DC voltage rating and wall for 800V pad. Do not reuse LV polyolefin shrink. Check that corner edges of the busbar are free of burrs that can pierce the wall. do not reuse LV polyolefin shrink. Check that corner edges of the busbar are free of burrs that can pierce the wall.Standards: UL 224 / ISO 6722 (HV cable), IEC 62631 (dielectric).
Feature and remaining-wall review
800V Busbar Heat-Shrink Tubing is cut to length before installation, and the adhesive-lined dual-wall grade needs a controlled heat profile for the adhesive to flow properly. Feature depth, edge distance and remaining wall are reviewed against critical geometries, with capability confirmed on your drawing rather than a blanket tolerance.
Inspection and traceability

Common questions
How do I select the right grade of 800V Busbar Heat-Shrink Tubing for High-Voltage Platforms?
Start with the duty for 800V Busbar Heat-Shrink Tubing: the voltage, the temperature it will see and the mechanical load in the assembly. Send those and we match them against the grades in the specification table on this page.
What material is used for 800V Busbar Heat-Shrink Tubing for High-Voltage Platforms?
The material is Heat-shrink tubing (polyolefin). Alternate grades can be quoted against your drawing.
Is material certification supplied with 800V Busbar Heat-Shrink Tubing for High-Voltage Platforms?
Every batch of 800V Busbar Heat-Shrink Tubing ships with a material COA. First-article inspection and dielectric strength testing are added when your specification calls for them.
Can 800V Busbar Heat-Shrink Tubing for High-Voltage Platforms be made to our drawing?
Bore, wall and cut length on 800V Busbar Heat-Shrink Tubing come from your drawing. Send the print with the quantity and the quote follows it.
