Laminated Bus Bar For Variable Frequency Drive
Products Description
Choosing our Laminated Bus Bar for Variable Frequency Drive provides you with an engineering-grade solution that significantly enhances system efficiency and reliability. Its core advantages lie in three dimensions: electrical performance, safety, and system integration.
Low Inductance, High-Efficiency Transmission: The layered structure minimizes loop inductance, reduces switching transient overvoltages, protects power devices such as IGBTs/MOSFETs, and improves the overall efficiency and lifespan of inverter drives and UPS systems.
High Current Density Bearing: Optimized conductor cross-section and heat dissipation design support continuous high-current operation with controllable temperature rise, adapting to high-load industrial scenarios.
Strong Electromagnetic Compatibility: The multi-layer shielding structure effectively reduces electromagnetic radiation and conducted interference, ensuring stable system operation in dense equipment environments.
Easy Installation and Maintenance: The integrated molding design reduces the number of connection points, lowers contact resistance and potential for failure, shortens on-site assembly time, and improves system maintainability.
Material Advantages: Ultimate Purity and Dielectric Strength Stretch
| High-Purity Oxygen-Free Copper (OFC) | High-grade oxygen-free copper strip is selected, with extremely low oxygen content and impurity precipitation, ensuring excellent electrical and thermal conductivity. Compared to ordinary brass or recycled copper, BusBar with PET Insulating Paper has a current-carrying capacity and softening temperature resistance. |
| High-Performance Multilayer Composite Insulation Film | Depending on the voltage level, pure PET, high-temperature resistant NOMEX paper, or high-frequency corona-resistant PP film composite structures are selected. These materials not only possess excellent electrical strength and extremely low dielectric constant, but also maintain mechanical toughness under long-term high-temperature baking at 130℃-155℃. |
| Environmentally Resistant Encapsulating Resin | The external insulation encapsulation uses epoxy resin or polyurethane systems with extremely high tracking index (CTI) to resist humidity, condensation, and metal dust contamination in UPS rooms or industrial sites. |

Detailed Showcase: A Masterpiece That Withstands High-Pressure Magnification
Precise Insulation Edge Covering
All perforated and cut edges utilize a special flanging or multiple-layer covering process to ensure the copper foil edges are completely wrapped, eliminating any exposed areas and preventing creepage even in high-humidity environments.
Anti-Loosening Thread Inserts
Mounting holes for IGBT module connections use high-strength steel wire thread inserts or embossed inserts to increase contact area and prevent screw slippage and arcing under strong vibration conditions.
End Corona-Proof Sealing Treatment
The cut-off end face of the Laminated Bus Bar for Distributing Power Backplane is the weakest link. We use high-strength epoxy resin for end potting and sealing to prevent moisture intrusion and end-face corona discharge.
Precision Positioning and Foolproof Marking
To complement automated assembly, optical positioning reference points are reserved on the Laminated Bus Bar for Router Backplane Distribution, and clear polarity markings and foolproof installation serial numbers are laser-engraved to ensure zero-error operation by production line workers.
