Injection Molded Busbar

RHI offers a wide range of premium copper busbar products, including rigid, flexible, insulated, and nickel/tin-plated options.

Each product undergoes stringent quality control and testing to ensure performance that surpasses industry standards. For high-performance and dependable solutions, RHI busbars are your top choice.

RHI manufactures lightweight aluminum busbar products, including stamped, dovetail, clinched, and copper-aluminum composite types.

These aluminium busbars serve as conductor connectors for cylindrical batteries, prismatic cells, and pouch batteries, offering notable advantages such as neat, efficient wiring and space-saving design.

RHI manufactures flexible-rigid composite busbars that combine the features of flexible and rigid busbars to provide excellent conductivity and efficient power transmission. Compared to pure rigid busbars, composite designs reduce weight, while the flexibility of the busbars simplifies installation, making them ideal for complex spaces, especially in the new energy sector.

RHI masters copper-to-aluminium technology, using aluminium as the primary conductor and copper at both ends of the busbar. This copper-aluminium composite busbar offers excellent electrical conductivity and heat dissipation while reducing weight and material costs. It is particularly beneficial in cost-sensitive applications, such as new energy vehicle engineering, providing economic advantages.

RHI specializes in injection-molded busbars, ideal for the power and new energy sectors. These busbars offer high customization and integrated molding, meeting complex design needs, reducing assembly time, and improving efficiency.
