The material of high voltage wire for electric vehicles meets the certifications of CQC1103-1105, TUV1908, DEKRA K175, EN50620, UL62, etc. The high voltage wire in the car meets the requirements of ISO6722, DEKRA K179, QC/T 1037-2016 and other standards. The high-voltage cables for electric vehicles have the advantages of environmental protection and non-halogen, soft, anti-cracking, oil and weather resistance, waterproof and anti-acid and alkali, excellent high and low temperature performance, and not easy to be stained with dust.
-I. What are the differences between electric vehicle high voltage wires and general wiring harnesses? 1, insulation check voltage is higher, AC 600V /DC 900V check voltage is 8KVAC 900V /DC 1500V check voltage is 10KV2, the outer layer of the wire can only be used in bright orange color 3, wear-resistant requirements stipulate the minimum number of times of reciprocation of 1000 ~ 1500 times 4, chemical impregnation time changed to 10 Seconds, highly corrosive such as gasoline, diesel fuel single impregnation after heat aging 240H, weak corrosive liquids such as coolant, glass water is divided into four impregnation, heat aging 3000H, and then winding and insulation test. 5, flame retardant requirements are higher, flame retardant test self-extinguishing time is required to be less than 30 seconds. The self-extinguishing time of GB/T 25085 and GB/T 25087 is less than 70 seconds.
