Epoxy Powder Insulated Bending Copper Busbars
Products Description
Epoxy Powder Insulated Bending Copper Busbars are busbar products that use highly conductive copper busbars as the core conductor, are custom-bent, and then have an epoxy powder insulation layer applied to the entire surface. They are not simply "conductor + coating," but rather functional components structurally designed to meet system integration needs.
Core structural features include:
Integral bent structure: Reduces connection nodes and improves current continuity
Full-coverage epoxy insulation layer: Provides uniform and stable electrical isolation
Rounded edges and corners: Prevents localized electric field concentration
Customizable size and routing: Matches the complex cabling requirements within UPS and server racks
This product is particularly suitable for power systems with extremely high requirements for insulation reliability, compact layout, and long-term operational safety.
Precision Manufacturing Process: Every Step Safeguards Quality
1. Raw Material Selection: High-purity electrolytic copper ingots conforming to standards are selected. Copper purity and impurity content are tested using a spectrometer to ensure the copper substrate has a conductivity of≥99.9% and meets mechanical property standards.
2. Substrate Processing: Copper materials are cut according to customer requirements. Cold rolling is used to increase copper density, enhance conductivity and mechanical strength, and ensure the substrate's dimensional accuracy meets design requirements.
3. Surface Pretreatment: The copper substrate undergoes sandblasting to remove the surface oxide layer and impurities, improving surface roughness. Degreasing and cleaning are then performed to ensure a clean surface, laying the foundation for coating adhesion.
4. Precision Bending: The pretreated copper substrate is placed in a CNC bending machine and precisely bent at multiple angles according to preset parameters. Stress changes are monitored in real time during bending to prevent cracks and deformation.
5. Electrostatic Spraying: Using high-voltage electrostatic spraying technology, modified epoxy powder is evenly sprayed onto the bent copper Epoxy Powder Coated Busbars, controlling the coating thickness to 0.2~0.5mm to ensure the coating is free of pinholes and bubbles.
6. High-Temperature Curing: The Epoxy Spray Copper Bus Bar is placed in a high-temperature curing kiln and held at 180~200℃ for 2~3 hours to fully cure the epoxy powder, forming a dense insulating layer.
7. Post-Processing: After curing, the product undergoes edge grinding and burr removal to ensure a smooth appearance without sharp edges, preventing damage to other equipment components during installation.
Product Advantages: Creating Multi-Dimensional Value for Projects
Space Optimization Master
The interior of a UPS power supply is extremely limited in space. Traditional straight Insulating Coatings Busbar connections require numerous joints and additional bends, consuming space and increasing resistance. Our integrated bending design, tailored to the installation path, significantly reduces connection points and installation space, making the UPS design more compact and achieving higher power density.
Installation Efficiency Revolution
For contractors, time is money. This Busbar Insulation Paint is pre-insulated and shaped at the factory. On-site installers simply need to secure it to the support and tighten the bolts. No cumbersome on-site heat shrink tubing or complex piping connections are required. This "plug-and-play" feature can improve on-site assembly efficiency by over 50%.
Extremely Low Maintenance Costs
Due to the extremely high mechanical strength and anti-aging properties of the epoxy powder layer, the Epoxy Powder Coating Insulated Copper Busbar system requires almost no maintenance during the UPS's 10-15 year lifespan. There's no need for regular checks for insulation aging and cracking, greatly reducing the difficulty and cost of later-stage data center maintenance.
Enhanced Safety eliminates exposed live parts
Effectively prevents accidental contact with live parts by maintenance personnel in densely populated maintenance passages or narrow machine rooms. Furthermore, the high flame-retardant epoxy material has self-extinguishing properties when exposed to open flames, providing a final line of defense for fire safety.
Why are they particularly important in UPS power systems?
UPS power systems are the last line of defense for ensuring the continuity of critical business operations. In a UPS system, the reliability of the connecting components directly determines the performance of the entire system. Our Epoxy Spray Copper Battery Bus Bars offer the following unique value in UPS systems:
Preventing internal short circuits: UPS systems have compact internal spaces, and any poor insulation can lead to short circuits. Our products provide superior insulation protection.
Reducing energy loss: In a UPS system, the resistance of the Epoxy Powder Coated Busbar Insulations directly affects system efficiency. Our products ensure minimal power loss.
Accommodating frequent switching: UPS systems require frequent switching between AC power and battery power. Our products can withstand this dynamic load, ensuring stable operation.
Extending system lifespan: Excellent insulation protection reduces electrical stress, extending the overall lifespan of the UPS system.
