Laminated Low Inductive Bus Bar
Products Description
Laminated Low Inductive Bus Bars are multi-layered composite power transmission core components designed specifically for UPS uninterruptible power supplies, servers, and data center power distribution systems. They are precisely composed by alternating layers of high-purity conductive copper and high-performance insulating media, featuring "low stray inductance, low impedance, high current carrying capacity, strong heat dissipation, and high integration." They replace traditional cables and single copper busbars, solving pain points such as voltage spikes, EMI interference, messy wiring, excessive temperature rise, and insufficient reliability in high-power, high-frequency switching scenarios. They are the "power highway" that ensures the efficient, stable, and safe operation of UPS/server systems.
Product Nature and Core Features: Electrical Optimization Beyond Physical Connections
Physical Attributes
Multi-layer Composite Structure: Utilizes alternating layers of refined conductive copper plates and high-performance thin films, forming physical characteristics similar to a supercapacitor.
Ultra-compact Design: Replaces tangled, thick cables, enabling high-density cabling within the confined space of a UPS cabinet.
Core Electrical Features
Ultra-low Stray Inductance: Compared to traditional parallel copper busbars, the close contact and opposite orientation of the positive and negative plates nearly completely cancel out the magnetic fields they generate for BusBar with PET Insulating Paper.
Uniform Characteristic Impedance: Ensures excellent voltage drop and spike suppression performance under high-speed dynamic loads.
Material Advantages: A Perfect "Sandwich" Balance Between Dielectric and Conductivity
| Introduction of High-Temperature, High-Breakdown Insulating Dielectric | Server power supplies operate at extremely high temperatures, accompanied by high-frequency ripple. We have abandoned conventional insulating tapes and adopted specially formulated PET (polyethylene terephthalate), PP (polypropylene), or even higher-grade Nomex (aramid) insulating films. These materials not only possess extremely high dielectric strength (breakdown resistance) but also extremely low dielectric constants. |
| Addressing the "High-Frequency Skin Effect" of Oxygen-Free Copper | High-frequency current does not flow uniformly across the conductor cross-section but concentrates on the surface (skin effect). We select high-purity T2 oxygen-free copper as the conductive layer, whose extremely high conductivity effectively reduces AC resistance at high frequencies. |
| The "thermal bridge" function of the thermally conductive insulation layer | In high-current UPS scenarios, the Power Distribution Unit BusBar itself generates a significant amount of heat. The special insulating film we selected not only provides insulation but also possesses excellent thermal conductivity (extremely low thermal resistance). |
