How RHI Electric Defines and Delivers Advanced Busbar Electrical Systems
Discover how RHI Electric designs and delivers advanced busbar electrical systems with precision, reliability, and innovation for modern power solutions.
Understanding the Busbar: Definition and Purpose
A busbar is a robust conductor—typically copper, aluminium, or a composite—used to efficiently distribute high currents in switchgear, EV packs, energy storage systems, and industrial control panels. Unlike traditional cable wiring, busbars allow power branching at multiple points, reduce wiring complexity, and offer superior heat dissipation, making them essential in today’s high-performance electrical environments.
RHI Electric treats its busbars as engineered systems, not just metal strips. Their product range spans rigid copper, flexible copper, aluminium, and copper–aluminium composite busbars, including injection-moulded designs optimized for new energy applications. They focus on conductivity, thermal performance, mechanical resilience, and compliance with international standards (IATF 16949, ISO 9001/14001/45001, RoHS, REACH) . This holistic approach ensures busbars meet specific electrical and mechanical demands while fitting neatly into compact layouts.
Materials and Design Excellence
From high-purity 1350 aluminium known for lightweight and corrosion resistance, to flexible-rigid copper composites that simplify routing in EV battery modules, RHI covers the full spectrum of busbar solutions. Customised copper–aluminium busbars offer the conductivity of copper at critical junctions while leveraging aluminium to reduce weight and cost—ideal for electric vehicle and renewable energy applications . Each design balances thermal dissipation, current capacity, and physical integration within constrained spaces.
Intelligent Manufacturing and Quality Control
On a 20,000 m² facility in Wenzhou, RHI employs automated bending, stamping, welding, injection moulding, and CCD visual inspections. Every project goes through DFM review, APQP/PPAP testing, and electrical/mechanical testing, including short‑circuit, pull‑off, and aging assessments. Such rigor, combined with UL/NEMA-grade coating options, ensures not just compliance but performance durability over time.
