- Product Introduction
Jinneng electrical 1kV 10kV 35kV heat shrink busbar insulation tubing is a thick-walled, heat-shrinkable polymer tube designed to provide electrical insulation, mechanical protection, and environmental sealing for copper or aluminum busbars. When heated, it shrinks tightly around the busbar, act as the protection layer.
● High Dielectric Strength
Withstands high voltages (1kV to 10kV+), preventing electrical leakage and short circuits.
● Thick-Walled Design
Provides enhanced mechanical durability against abrasion, impact, and corrosion.
● Heat-Activated Shrinkage
Shrinks instantly (typically 50% shrinkage ratio) to conform tightly to irregular busbar shapes.
● Environmental Resistance
Resists moisture, chemicals, UV radiation, and extreme temperatures (-55°C to 135°C).
● Flame Retardancy
Complies with UL/VDE standards for fire safety in electrical applications.

Selection Guide
1. Voltage Rating
Choose based on operational voltage (600V, 1kV, 10kV,35kV).
2. Busbar Dimensions
Choose inner diameter to fit the busbar's widest point (typically 1.2-1.5x larger).
3. Material Compatibility
Ensure compatibility with copper/aluminum and operational environment (oil-resistant, UV-stable).
4. Certifications
With UL, VDE, RoHS, or IEC standards compliance.
Our heat shrink tubing use high quality raw material,all product has RoHS certificate.
