Multi-Layer Composite Structure Connection Bar
Products Description
A Multi-Layer Composite Structure Connection Bar is an integrated conductive assembly formed by bonding multiple layers of conductors-typically copper or aluminum-with high-performance insulating materials through a lamination process. Its core lies in a multi-layer composite structure of "conductor-insulator-conductor," which renders current paths more controllable and electrical performance more stable.
Typical Structural Components:
Multi-layer conductive layers (copper/aluminum)
Insulating layers with high dielectric strength (PET, PI, or epoxy composites)
Customized terminal connection zones
Structures formed via integral stamping or CNC machining
This structure not only reduces system parasitic inductance but also enhances overall mechanical strength and installation consistency.
Manufacturing Advantage: Digitally Driven Precision Processes
Fully Closed-Loop Hot Press Control
Utilizing precision-programmable hot presses, we continuously monitor pressure, temperature, and time profiles. This ensures the complete absence of microscopic voids between the insulation layer and the conductor, thereby thoroughly eliminating any risk of Partial Discharge.
Streamlined CNC Machining
To accommodate the complex internal wiring layouts typical of UPS systems, we employ 5-axis machining centers to shape our conductors. This guarantees absolute precision regarding bending radii and mounting hole alignment.
Non-Destructive Testing
Every partially laminated bus bar undergoes rigorous testing, including withstand voltage tests, partial discharge tests, and precise inductance measurements.
Application Advantages
UPS Power Modules: Dual Enhancement of EMC and Power Density
Within the power units of modular UPS systems, the low-inductance characteristics of Three-layer laminated busbars reduce the burden on EMI filters, while their compact structure supports higher power density; furthermore, the modular design facilitates hot-swappable maintenance.
Server Power Supplies: Low-Loss Transmission for 48V DC Distribution
In response to the evolving 48V DC architecture in data centers, the low-loss characteristics of Laminated bus bars, passive electronic components-particularly during high-current, low-voltage transmission-translate directly into improved energy efficiency and reduced thermal loads.
New Energy Storage: High-Reliability Inter-Battery Cluster Connections
The parallel connection of battery clusters in energy storage systems requires busbar connections characterized by low impedance and high reliability; laminated busbar in High Power Converters address this need by utilizing flexible sections to accommodate mechanical tolerances within the battery racks, while rigid sections ensure stable electrical performance.
Design Advantages: Empowering Your System Space
"Modular" Integration: We can directly integrate components-such as fuse holders, sensors, and capacitors-onto the Laminated Busbar for Electric Car itself, thereby significantly reducing the workload on downstream assembly lines.
Enhanced Space Utilization: Compared to cluttered wire harnesses, High Voltage Explosion-Proof Inverter Busbars are typically less than one-third the thickness, freeing up valuable cabinet space to create additional airflow channels for cooling.
Foolproof Design: The physical structure dictates a single, unique installation path, eliminating the risk of wiring errors during on-site assembly.
