Powder Coated Bus Bars
Products Description
Powder Coated Bus Bars use high-purity copper or aluminum as the base conductor, with a uniform insulating layer formed on the surface through electrostatic spraying. After high-temperature curing, a continuous, dense, and mechanically strong protective interface is achieved. Compared to traditional heat-shrink tubing or tape insulation, powder coating is an integrated insulation structure with higher consistency and stronger environmental resistance.
Its core structure includes:
Highly conductive metal substrate: ensuring low impedance and excellent current-carrying capacity
Thermosetting powder insulation layer: forming stable electrical isolation and surface protection
Interface bonding layer: improving adhesion and peel resistance
Customizable end treatments: adaptable to screwed, welded, or composite connection structures
This multi-layered synergistic structure gives the busbar electrical, mechanical, and environmental stability.
Manufacturing Advantages: Lean Manufacturing and Customization Capabilities
Fully Automated Coating Line
Utilizing fluidized bed or electrostatic spraying technology, we ensure coating thickness tolerance is controlled within 0.05mm/pm, meeting the assembly requirements of precision electronic equipment for Epoxy Powder Coating Insulated Copper Busbar.
High-Precision Forming Process
Equipped with a multi-axis CNC bending center, ensuring near-zero conductive cross-sectional area loss at bends during the forming of high-current thick busbars.
Surface Pretreatment
Rigorous degreasing, pickling, and phosphating processes enhance the coating's corrosion resistance and long-term stability.
Class 10,000 Cleanliness Control
For server-grade customers, the production environment is strictly dust-controlled to prevent breakdown risks caused by impurities in the insulation layer for Insulated Copper Bus Bar.
Material Advantages and Design Innovation: From Microscopic Material Selection to Macroscopic Architecture
Deep Application of Materials Science
We focus not only on conductivity but also on the compatibility of material interfaces in our material selection for Epoxy Spray Copper Battery Bus Bar.
Substrate Selection
We use high-purity T2 copper or 6063 aluminum alloy to ensure low impedance. For copper-aluminum transition requirements, we employ friction or flash welding processes and coat the weld seams to eliminate the risk of corrosion arising from potential differences at the contact surface.
Powder Coating Formulation
Based on the UPS application scenario, we have customized a mixed formulation of epoxy resin and polyester resin. Epoxy resin provides excellent adhesion and insulation, while polyester resin provides superior UV resistance and weather resistance. The combination ensures that the coating does not become brittle or peel off under long-term power-on heating conditions.
Engineering Freedom in Design
Powder coating technology gives the Epoxy Powder Coated Busbar Insulation design a high degree of freedom. For complex UPS internal structures, we support:
Multi-dimensional Bending: Supports three-dimensional bending designs. The coating not only does not peel off at the bending points but also becomes more robust due to the uniform tension distribution.
Customized hole positions and interfaces: All punching and tapping processes are completed before spraying, and the connecting surfaces are precision-machined to ensure flatness of the overlapping surfaces and minimize contact resistance. The coating around the mounting holes is smooth, without powder accumulation or drips, ensuring good contact of the mounting gaskets.
