CTOnews.com May 11 news, Shin Yue Chemical Company released a new plastic silicone-based rubber KE-5641-U. This new type of silicone-based rubber can be used in high-voltage cable sheath of electric vehicles. Compared with the traditional sheath material, this new material improves the flexibility of the cable and reduces the weight. The company aims to expand sales by taking advantage of higher-voltage commercial opportunities in the drive systems of electric vehicles (EV) and other electric-driven vehicles.

CTOnews.com learned that the voltage resistance of Xinyue's new silicone gel has reached the highest level in the industry, and its dielectric breakdown strength is 40kV / mm, which is about 54% higher than that of traditional silicone products. Higher unit voltage withstand characteristics mean that the same insulation performance can be maintained in thinner high voltage cable sheath, thus increasing the flexibility of the cable, resulting in thinner cable diameter and lighter weight.

According to reports, the internal wiring length of Tesla Model Y and other new energy vehicles is more than 100m, and the internal wiring of some vehicles is even more than 1000 m, just like the length of blood vessels in the human body. The disadvantage of traditional cable sheath materials is that when trying to ensure insulation, the sheath becomes thicker, making the car heavier. Therefore, automobile manufacturers require high-voltage cables to have good flexibility and lightweight characteristics to facilitate wiring work. Xinyue's new silicone greatly optimizes the wiring weight and improves the energy efficiency of the vehicle.

Xinyue Chemical has currently sent samples to automakers, but the timing of mass production has not yet been set. In addition to automotive applications, this new silica gel can also be used as sheath material for high voltage cables in industrial machinery, railway equipment, power plant energy storage and other applications.
