Silicone Rubber Used In High-Voltage Wiring Harness For New Energy Vehicles

There is no doubt that new energy vehicles have become an important development trend in the future. However, due to the safety issues of new energy vehicles, the trust of domestic and foreign users in new energy vehicles has grown very slowly over the years.

According to the "New Energy Vehicle National Supervision Platform Big Data Safety Supervision Achievement Report", since May 2019, the new energy vehicle national supervision platform has discovered 79 safety accidents of new energy vehicles, involving 96 vehicles. Among them, 47 accident vehicles were connected to the national supervision platform, and 28 accidents had been warned by the national supervision platform within 10 days before they occurred.

Automobile safety is the most concerned issue of automobile consumers in China and the world. Compared with ordinary fuel vehicles, new energy vehicles are more prone to safety problems in high-voltage connections, such as overload, short circuit, spontaneous combustion, and current leakage.

Silicone Wire Seal

The silicone harness seal in the new energy vehicle is like the “blood vessel” of the vehicle, which penetrates all parts of the vehicle, connects all electronic components, and transmits power and data. It mainly provides high-voltage and strong electric power supply for vehicles. It is a high-safety part, with the characteristics of large voltage/high current, large wire diameter and a large number of wires, and many parts such as inverters, transformers, air-conditioning compressors, etc. need to be used Large diameter wire.

The pressure faced by the automotive wire harness seals: the voltage of the new energy vehicle battery can reach 600V, and the peak current of the corresponding wire can reach 300A. The traditional fuel vehicle battery voltage is a safe voltage, generally 12V.

Therefore, the design of high-voltage wiring harnesses is facing huge challenges, and how to select materials has naturally become a top priority. Is there such a material that has excellent insulation, heat resistance, and good flame retardancy? In the process of producing high-performance new energy vehicles, silicone materials play a vital role. Because they are widely used in various solutions, such as the assembly and protection of key automotive components. The high-voltage wiring harness for vehicles made of this material can meet the long-term high-current full-load operation requirements and prevent spontaneous combustion of the vehicle.

Silicone Wire Seal is widely used in the bonding and sealing of components in electronic appliances to effectively isolate bad environmental pollutants from the outside world, and at the same time ensure that the components can work in various environmental temperatures, humidity, and other harsh environments Under maintain its physical and electrical characteristics.
