Advantages and related analysis of PVC dipped flexible copper processing for insulation and high temperature resistance

The core of immersion processing is to completely immerse PVC dipped flexible copper into polymer materials with high temperature resistance, corrosion resistance, and insulation properties such as modified polyethylene and epoxy resin, forming a uniform and dense protective coating. Compared to traditional spraying and electroplating processes, the immersion layer is more tightly bonded to the copper busbar substrate, with no pores or gaps, effectively isolating environmental factors such as moisture and salt spray from corroding the copper busbar.

The complete dipping process includes four key steps: pretreatment, preheating, dipping, curing and cooling. Each step requires strict control of temperature and time parameters to ensure that the coating thickness is stable between 0.5-2mm and the adhesion meets industry standards, providing comprehensive protection for PVC dipping insulated busbars. ​

The PVC dipped flexible copper treated by immersion molding has outstanding comprehensive performance and can adapt to harsh use scenarios such as high pressure, high temperature, and complex environments. In terms of insulation performance, its surface resistance can reach over 10 ΩΩ, which can meet the safety distance requirements of high-voltage equipment and effectively eliminate the risk of leakage; Excellent high temperature resistance, with a long-term use temperature range covering -40 ℃ to 150 ℃, and a short-term tolerance for high temperature peaks up to 200 ℃, suitable for operation under high temperature conditions;

The weather resistance performance is outstanding, and the ability to resist UV aging and chemical corrosion is far superior to ordinary coatings, extending the service life of copper bars. In addition, Insulated custom copper bus bar with PVC dipping has precision machining characteristics and dimensional tolerances can be controlled within ± 0.1mm, which can meet the design requirements of compact equipment and improve equipment space utilization. ​

Professional immersion processing requires multiple quality control processes to ensure stable and reliable performance of the Insulated flexible copper bus bar for power battery pack. Strict testing will be conducted on the dipping materials during the raw material process to ensure compliance with RoHS environmental standards; Automated dipping equipment is used in the production process, coupled with infrared thermometers to monitor the curing temperature in real time, to avoid problems such as bubbles and delamination in the coating;

The finished Plastic dipping copper busbar must undergo rigorous testing such as salt spray test (96 hours without corrosion) and pressure test (5000V without breakdown). Unqualified products are strictly prohibited from leaving the factory. In terms of production capacity, under batch production mode, the daily production capacity of a single production line can reach 500 meters, while supporting non standardized size and shape processing. Mature technology and strict quality inspection system can ensure the outdoor service life of products for more than 10 years, effectively reducing equipment maintenance frequency and costs. ​

Standardized operation can maximize the performance advantages of Soft connection copper busbar and extend the overall lifespan of the equipment. During installation, it is necessary to avoid mechanical scratches on the coating. The bending radius of the copper bar should be greater than three times its thickness to prevent coating cracking; If the ambient temperature exceeds the calibration range, it is necessary to use heat dissipation design or select a higher temperature resistant immersion material;

During the daily use of PVC dipped laminated flexible copper, it is necessary to regularly check the integrity of the coating. If any local damage is found, it should be repaired or replaced in a timely manner; When storing, it should be kept away from strong acid and alkali environments, avoid direct sunlight, and prevent accelerated aging of the coating.
