At present, the new energy automotive cable industry market is widely used around the world, and professional cable manufacturers understand the technology of cable production. The following is by understanding the differences in the characteristics of the materials used in cables:

Among them, XLPE or silicone rubber cables are mainly used for high-voltage cables in vehicles. The characteristics of both materials are highlighted in the performance.

Since the XLPE process is relatively mature, manufacturers can add cross-linked masterbatch for direct production, and the cost and construction period are relatively low. At present, domestic automobile manufacturers mainly choose to use XLPE.

The high temperature resistance (-50℃--180℃) and flexibility of silicone rubber cables are very helpful for in-car wiring. Foreign manufacturers mainly choose silicone rubber cables, such as Klopp, Leoni, Live electric, Kroschu, etc. Domestic manufacturers are also trying to develop silicone rubber cables. The main difficulty lies in the optimization of the synthesis ratio of silicone rubber materials and the optimization of the process. At present, foreign-funded enterprises do not have silicone thread production lines in China, and their products still rely on imports.

The characteristics of low-voltage automotive wiring harness models vary widely. 70% of manual production results in low gross profit margin and production efficiency. The future direction is to seek standardized parts in customization, as well as cable pre-processing and pre-assembly. process, continuously improve the level of automation, improve efficiency and gross profit margin. In comparing high-voltage wire harness production standards, high-voltage wires require calibration of instruments and equipment with high performance requirements.
