Inverter Bus Bar
Products Description
What is an Inverter Bus Bar? It is a copper DC connection component specifically designed for power electronic inverter systems. Through its low-inductance design and high-conductivity materials, it achieves efficient power transmission and distribution. As the core connection medium on the DC side of the inverter, this busbar plays a crucial role in connecting IGBT modules, capacitor banks, and input/output terminals, providing a stable and reliable electrical connection solution for new energy, industrial automation, and power transmission equipment.
Product Advantages
High Consistency of Electrical Parameters
Unlike manually wired cables, BusBar in Substation are molded in one piece, ensuring that the resistance, inductance, and impedance characteristics of each batch are exactly the same, eliminating unbalanced current in distributed circuits.
Significantly Reduced Assembly Error Rate
The structured Tinned Copper BusBar have a "foolproof" property, simplifying the installation process for production line workers and reducing the risk of system burnout due to loose wiring or reversed polarity.
Adaptability to Harsh Mechanical Environments
The rigid copper structure of Industrial BusBar has extremely strong vibration and shock resistance, providing greater structural stability than flexible cables in high-mechanical-stress scenarios such as electric vehicles (EVs) or wind turbine pitch systems.
Design Advantages
Minimize Inductance
The recommended insulation thickness between positive and negative BusBar Electric is 0.125-0.25mm. Wider overlap width and shorter length are preferable. Avoid opening holes or cutting grooves in the overlap area.
Overlap Surface Treatment
The overlap surface between the IGBT module terminals and theCopper BusBar for Siemens should be designed as a flat contact. The recommended torque value is determined according to the terminal specifications (e.g., 6-8 N·m for M6 bolts). Tin plating the overlap surface prevents oxidation and reduces contact resistance.
Insulation Material Selection
PET offers high cost-effectiveness (temperature resistance 105℃), polyimide is heat-resistant (200℃), and Nomex has a high flame retardant rating (UL94 V-0). Select according to the operating temperature and environment for BusBar for Bussmann.
Frequently Asked Questions
Q1: What material is used for the Tinned Copper BusBar?
A1: C11000 oxygen-free copper, with a purity of 99.9% or higher, ensuring excellent conductivity.
Q2: How is the insulation withstand voltage rating of the BusBar in Substation determined?
A2: It is selected based on the system operating voltage, commonly ranging from 500V to 3000V. Specific ratings should be referred to the design specifications.
Q3: How does the plating thickness affect performance of Industrial BusBar?
A3: A 5-15 micrometer tin plating layer balances conductivity and protection. Too thick a layer increases resistance, while too thin a layer reduces protection.
