PVC Insulation Bus Bar
Products Description
PVC Insulation Bus Bars are not simply a combination of bare copper and sheathing. Instead, they utilize an integrated dip-coating process to create a tight bond between the PVC insulation layer and the copper substrate, resulting in the following structural features:
Continuous overall coverage: The insulation layer is seamless and without gaps, avoiding partial discharge and creepage risks.
Uniform coverage at corners and edges: The insulation thickness is stable at busbar corners and edges, eliminating weak points.
Smooth and dense surface: Facilitates subsequent assembly, fixing, and system integration.
Coordinated conductor and insulation design: Balancing current-carrying capacity and safe clearance within a limited space.
This structural form is particularly suitable for compact and complex new energy power systems.
Core Technological Features Highlight Differentiated Competitiveness
| Precision Copper Conductor Forming Technology | Utilizing a cold extrusion forming process, compared to traditional hot processing, this effectively preserves the excellent conductivity of copper while improving the dimensional accuracy and surface finish of the conductor. Through precise mold design and process parameter optimization, conductors with complex cross-sectional shapes can be formed to meet the conductive connection requirements of different equipment. |
| Integrated Dip-Coating Insulation Technology | Our independently developed dip-coating process achieves a tight bond between the insulation layer and the conductor. By controlling the dip-coating temperature, time, and cooling rate, we ensure uniform insulation layer thickness, free from defects such as bubbles and pinholes. Simultaneously, a specialized adhesive technology enhances the adhesion between the insulation layer and the conductor, eliminating the risk of insulation layer peeling during long-term use. |
| Wide Temperature Range Adaptability Optimization Technology | Targeting the extreme temperature conditions in the new energy field, we have improved the wide temperature range adaptability of our products through formula optimization of PVC insulation materials and design improvements to the conductor structure. In low-temperature environments, it ensures the insulation layer does not become brittle and the conductor performance remains stable; in high-temperature environments, Dipped Insulated Copper Busbar possesses excellent heat resistance, preventing the insulation layer from aging and deteriorating. |
| Anti-interference shielding technology | An optional shielding layer design, by adding specialized shielding material outside the insulation layer, effectively resists external electromagnetic interference, ensuring the stability of current transmission. This technology is particularly suitable for scenarios with complex electromagnetic environments, such as high-voltage systems in new energy vehicles, improving the overall reliability of equipment operation. |
Scientific Design Concepts Enhance Adaptability and Practicality
Modular Design
Utilizing a modular design concept, conductors, insulation layers, and connecting terminals are designed as standardized modules. These modules can be quickly combined and matched according to customer needs, enabling rapid customization of Dipped plastic busbars of different specifications and improving order response speed.
Lightweight Design
Addressing the lightweight requirements of new energy vehicles, while ensuring product performance, we reduce product weight by optimizing conductor cross-sectional structure and selecting lightweight insulation materials. Compared to traditional products, weight can be reduced by 10%-15%, contributing to improved driving range for new energy vehicles.
Optimized Protection Design
We reinforce vulnerable areas such as Pvc Insulated Busbar ports and bends, increasing insulation layer thickness or using protective sleeves to improve wear and impact resistance. Additionally, we add anti-slip textured designs to the insulation layer for easy gripping and securing during installation.
