Epoxy Powder Coated Busbars
Products Description
This Epoxy powder coated busbars uses high-purity copper or aluminum busbars as the conductor substrate, with an electrostatically sprayed epoxy powder coating and high-temperature curing to form an integrated insulating protective layer. It is suitable for:
UPS uninterruptible power supply systems
Data center server power distribution systems
High-density distribution cabinets and modular power units
Industrial-grade backup power supplies and critical load systems
Its design goal is not simply "protection," but rather to create a busbar solution that balances conductivity efficiency, insulation safety, and system integration friendliness.
Technical Features: Balancing Dielectric Strength and Thermal Management
Excellent Dielectric Strength
As an insulating layer, epoxy resin possesses extremely high volume resistivity and breakdown voltage. In UPS high-voltage DC applications, Epoxy Powder Coated Busbars effectively prevent micro-discharges and electrical treeing, ensuring no breakdown or aging under long-term high-voltage operation.
Superior Thermal Conductivity
Overheating is a major concern in data centers and server rooms. Traditional PVC or heat-shrinkable materials have extremely low thermal conductivity, essentially covering the Epoxy Spray Copper Bus Bars with a "quilt." The dense layer formed after epoxy powder coating cures, though extremely thin, has far superior thermal conductivity compared to traditional plastics.
Weather Resistance and Aging Resistance
Epoxy resin is a thermosetting material; once cured, Insulated Copper Bus Bar will not melt even upon reheating. This allows the coating to maintain stable physical properties even under long-term high-temperature environments (such as inside a UPS), without softening or deforming due to heat, thus eliminating the risk of short circuits caused by insulation aging.
Material Advantages: A Performance Leap Forward Through Chemical Formulation
We adhere to top-tier standards in raw material selection, using only high-performance thermosetting epoxy resin powders.
Environmentally Friendly Formula: Our powders are solvent-free, belonging to 100% solids coatings. No volatile organic compounds are generated during spraying and curing, meeting international environmental standards and providing a healthy working environment for workers.
Halogen-Free Flame Retardant Properties: For fire safety in data centers and public places, we use a halogen-free flame retardant formula. When exposed to open flames, it produces extremely low smoke and no toxic or corrosive gases, greatly improving the safety probability of personnel escaping in the event of a fire, meeting the UL 94 V-0 flame retardant standard.
Customizable Colors: In addition to standard insulation colors (such as red, blue, and black), we can formulate epoxy powders of various colors according to customer project requirements, enabling color-coded management of Busbar Insulation Paint systems, facilitating engineers' quick identification of phase sequence or voltage levels.
Application Advantages: Deep Adaptation to Critical Power Scenarios
| Modular UPS with Three-Dimensional Insulation Solution | For the drawer-type structure of modular UPS, we have developed a three-sided adaptive coating technology to ensure complete protection for any exposed surface of the Busbar Bonded Powder Coating during insertion and removal. The coefficient of friction of the coating surface has been optimized (μ=0.15-0.25), reducing module insertion and removal force by 40% while ensuring contact stability, perfectly resolving the insulation and connection contradictions in compact UPS. |
| A Revolution in Vertical Power Distribution for Server Racks | The vertically mounted busbar system designed for high-density server racks employs a differentiated front and rear double-coating design: a thin coating with high thermal conductivity on the side facing the heat dissipation duct, and a thick coating with high insulation on the back side. This asymmetrical design reduces the temperature difference of the Epoxy Bus Bar Coating within a 2400mm height to within 5℃, supporting an increase in rack power density from 8kW to 15kW without changing the basic architecture. |
| Harsh Environmental Adaptability of Industrial UPS | Addressing the challenges of dust, moisture, and chemical corrosion in industrial environments, the coating system integrates self-cleaning and self-repairing functions. The surface's micro-nano structure prevents dust adhesion, and special additives can automatically migrate and repair micro-damage to the coating, maintaining insulation integrity. This characteristic extends the maintenance-free life of the Powder Coated Bus Bars to 10 years in harsh industrial environments such as petrochemicals and metallurgy. |
