Eight materials and standards commonly used in EV cables: At present, the eight materials commonly used in wire and cable are XLPE, TPE, TPV, TPU, EPR, PVC/HNBR, silica gel, and CPE/CR. 1. Application of XLPE in EVs XLPE is mainly used for high-voltage wires in cars. Its temperature resistance is so good that it will burn red with a soldering iron, and it will not be damaged after being placed on it for 10-20 seconds. It is expected that XLPE will be the main material for high-voltage wires in cars in 2017. Advantages: 1) Mature application, complete technology and supporting solutions, high cost performance; 2) High heat resistance, up to 150 degrees; 3) Because it is a thermosetting material, it is insoluble and infusible, short circuit and thermal shock resistant, crack and tear resistant 4) Low-smoke and halogen-free, high light transmittance, and good environmental protection; Disadvantages: 1) Compared with TPER, it is not soft enough, and the larger square (70-150) cable is harder; 2) It needs radiation crosslinking, and the process is long , which is inconvenient for areas without accelerators; 3) Poor anti-scratch whitening performance, easy to scratch; 4) Contradictory volume resistivity and flame retardancy; Standards for different application fields: High voltage lines: ISO 6722, QC/T 1073, CQC1122/ DECRAK179 Charging cable: CQC1103-1105, DECRA K1752. Application advantages of TPE in EV: 1) adjustable softness, 60-90A, good touch; 2) small specific gravity, 0.9-1,15, high cost performance; 3) liquid resistance Good performance, wire diameter change<15%; 4) Simple processing; 5) High electrical performance; Disadvantages: 1) There were too many cracks in the past few years, which caused distrust in the industry; 2) The low-hardness formula is easy to precipitate oil, and the surface is sticky and dusty; 3) The ink is not easy Adhesion, poor printing; Standards for different application fields: high voltage line ISO 6722, QC/T 1073, CQC1122/ DECRA K179 charging line CQC1103 -1105, DECRA K175 EN50620, UL623. TPU application in EV TPU is mainly used in Europe At present, some large cable factories in South China and Central China want to develop TPU materials. Advantages: 1) Good wear resistance, tear resistance and bending resistance, can be used in thin walls; 2) Good mechanical properties, strength 20-40mpa; 3) Oil resistance, water resistance and weather resistance; 4) Halogen-free flame retardant, high environmental protection; 5) Good High and low temperature performance; Disadvantages: 1) Poor processability, too narrow processing window, very strict requirements on equipment and technology, easy to vent holes, particles, surface defects and other phenomena during processing; 2) High price, mostly dominated by foreign manufacturers; Application standards: Charging cables CQC1103 -1105, DECRA, K175 EN50620, UL62 Friends who are involved in the charging pile industry can add editors to WeChat 178170997094. The application of EPR in EV EPR is widely used in Europe, and is generally used in charging pile core wires . Advantages: 1) Excellent heat resistance, up to 150 degrees; 2) Soft 70-90A; 3) Thermosetting, heat resistance and short circuit impact; 4) Low smoke and halogen-free, high light transmittance; 5) High electrical performance Disadvantages: 1) Poor oil and tear resistance; 2) Need irradiation crosslinking or vulcanization; Standards for different application fields: high voltage line ISO 6722, QC/T 1073, CQC1122/ DECRA K179 charging line CQC1103 -1105, DECRAK175, EN50620, UL625. Application of silicone in EV Advantages: 1) Excellent heat resistance, up to 200 degrees; 2) Soft 60-85A; Disadvantages: 1) Requires a special vulcanization production line; 2) Crack resistance, tear resistance The cracking performance is not good; application standards: ISO 6722, QC/T 1073, CQC1122/ DECRA K1796. Application of PVC/HNBR in EV This material is currently used the most in China due to its excellent feel and softness. Due to the presence of halogens, environmental issues remain to be resolved in the future. Advantages: 1) Excellent heat resistance, up to 125 degrees; 2) Softness 70-85A; 3) Good gasoline resistance; 4) High-grade texture, good hand feeling; 5) Crack resistance, tear resistance; Disadvantages: 1 ) The hardness increases a lot at low temperature; 2) The specific gravity is large, and the cost performance is not high; 3) It is not environmentally friendly; 4) The volume resistivity is low; Application standards: Charging line: CQC1103-1105, DECRAK175, UL627.CPE/CR in EV Application advantages: 1) high cost performance; 2) soft 60-85A; 3) good oil resistance; 4) thermosetting vulcanizate; 5) anti-cracking; ) The material is not environmentally friendly; application standards: charging line: CQC1103/CJS4522 Friends who are involved in the charging pile industry can add editors to WeChat 178170997098. The application of TPV in EV TPV appears less in the market, because the processing temperature is high, more than 200 If there is no suitable color masterbatch, it is easy to change color. Advantages: 1) Excellent heat resistance, up to grade 150; 2) Good gasoline resistance; 3) Crack resistance, tear resistance; Disadvantages: 1) Melt is too hard, poor processability; 2) Halogen-free flame retardant Difficult to make, low strength; 3) Relatively low cost performance compared to TPE; application standard: charging cable: CQC1103 In summary, it is a huge piece“cake”, Undoubtedly let TPE manufacturers salivate. The rapid development of charging piles is bound to accelerate the development of the TPE cable industry, but in the face of“High standards, many tests, inconsistent standards”For these problems, only by strengthening the research and development of the performance of TPE charging pile cables and meeting the requirements of various standards, can it occupy an important position in the charging pile cable industry. evcome-High-quality new energy charging pile cable research and development manufacturer. .
