Detailed explanation of high temperature resistant Dip insulated copper bus bars technology - providing reliable connection solutions for new energy and industrial electrical systems

Immersion molding is an important process for surface insulation and protection treatment of Dip insulated copper bus bars. By immersing the copper bars as a whole into polymer insulation materials such as modified polyethylene and epoxy resin, a uniform and dense protective layer is formed. Compared to traditional methods such as spraying and electroplating, the immersion layer is more tightly bonded to the copper busbar substrate, with no pores or gaps, which can effectively block external erosion such as moisture and salt spray.

The complete process flow of PVC dipping insulated busbar includes steps such as oil and rust removal pretreatment, preheating, plastic immersion, curing and cooling. Each step requires strict control of temperature and time to maintain a stable coating thickness of 0.5-2mm and ensure good adhesion.

The Insulated custom copper bus bar with PVC dipping treated by immersion molding has outstanding comprehensive performance and can meet the requirements of high pressure, high temperature, and complex working conditions. In terms of insulation performance, its surface resistance can reach more than 10 ΩΩ, which can meet the safe insulation spacing of high-voltage equipment; Excellent high temperature resistance, with a long-term use temperature range of -40 ℃ to 150 ℃ and a short-term ability to withstand temperatures up to 200 ℃; The weather resistance and corrosion resistance are equally outstanding, with significantly better resistance to UV aging and chemical corrosion than ordinary coatings. In addition, PVC dipped insulated bus bars have high processing accuracy and dimensional tolerances can be controlled within ± 0.1mm, making them suitable for various compact electrical equipment structural designs.

With characteristics such as insulation, high temperature resistance, and weather resistance, Insulated flexible copper bus bar for power battery pack has been widely used in the fields of new energy and industrial electrical. In the new energy sector, it is mainly used for key equipment such as photovoltaic inverters, energy storage battery clusters, charging piles, etc; In the industrial field, it is commonly found in motor controllers, high and low voltage distribution cabinets, and other places with high requirements for moisture resistance, dust prevention, and insulation. Its stable performance and precise size make it an important component for improving safety and reliability in modern electrical systems.

Professional Plastic dipping copper busbar rely on a comprehensive quality system to achieve stable delivery. From raw material testing to ensure compliance with RoHS environmental requirements, to the use of automated equipment and real-time infrared temperature monitoring in the production process, to the strict inspection of finished products such as salt spray testing and pressure resistance testing, the product performance is fully guaranteed. The large-scale production line has high production capacity and can support customized non-standard sizes and irregular structures. The reliable coating quality can achieve an outdoor service life of more than 10 years, effectively reducing equipment maintenance costs in the later stage.
