Electrical Automotive Insulated Copper Bus Bar
Products Description
Electrical Automotive Insulated Copper Bus Bars are power transmission components that combine highly conductive copper bars with multi-layer insulation materials. Their structure typically consists of the following components:
High-purity electrolytic copper conductor layer
PET insulation paper/composite insulation film
Bonding and lamination layer
Connection and termination zone (areas for cutouts, welding, or connections)
This structure enables the busbar to maintain excellent electrical conductivity while ensuring stable voltage withstand capabilities and resistance to environmental interference.
Material Advantages
Superior Electrical Insulation
High breakdown voltage and low dielectric loss minimize energy waste and enhance system safety.
Stable Thermal Performance
Excellent thermal conductivity and resistance to thermal aging ensure the insulation layer neither softens nor decomposes in high-temperature environments.
Mechanical and Chemical Compatibility
Good flexibility facilitates easy lamination and forming; resistance to chemical corrosion makes the IGBT Bus Bar suitable for the complex internal environment of battery packs.
Eco-friendly and Sustainable
The material is highly recyclable, aligning with green manufacturing trends in the new energy vehicle industry.
Application Advantages
Custom-engineered for film and supercapacitors
Whether for DC-link or high-frequency filtering applications, our EV Laminated Busbars ensure seamless terminal-level connections and minimize contact resistance.
Enhanced system-level power density
The compact PET-insulated design enables denser capacitor array layouts, supporting vehicle lightweighting and miniaturization goals.
All-climate adaptability
Meets rigorous environmental standards across global regions, maintaining stable electrical performance in extreme cold, high humidity, and high-salinity environments.
Design Advantages
Modular 3D Layout
Busbar for DC-Link Capacitor Supports custom designs for positive/negative electrode stacking, embedded copper pillars, conductive vias, and insulation pads, enabling single-step installation and minimizing on-site assembly errors.
