【Abstract】This paper mainly summarizes three commonly used shielding methods for high-voltage wire harness at present. By analyzing and comparing several shielding structures and their advantages and disadvantages，it is found that there are two main trends in the development of high-voltage wire in the future，namely： ① optimize the current braided shielding structure of wire to reduce its cost and make it easier to process；② High voltage wire is unshielded.

【Key words】high voltage harness；electromagnetic shielding；wire unshielding；shielding sleeve；wave filter

当前新能源汽车正朝着高电压大电流方向发展，有的高压系统承受的电压高达800V，电流高达660A，如此大的电流和电压会产生电磁辐射，电磁辐射会干扰其它电子元器件的正常运行，所以高压线束在设计时必须要考虑电磁干扰问题。（剩余2837字）
