Major introduction

A core major focused on high-voltage power equipment and insulating materials to ensure safe and efficient grid operation.

Program overview

High Voltage and Insulation Technology is a hardcore yet practical direction in electrical engineering. Simply put, it's about safely delivering electricity to every home—from step-up at power stations, long-distance transmission, to final step-down. All high-voltage equipment (transformers, circuit breakers, cables, insulators) involved in design, testing, and maintenance relies on this major. Core courses include High Voltage Engineering, Dielectric Physics, Insulation Testing Technology, Overvoltage and Protection, and Power System Transient Analysis. You'll learn how to perform withstand voltage tests on equipment, select insulating materials (gas, liquid, solid), and prevent lightning strikes and switching overvoltages. This major suits students passionate about physics and electricity, who enjoy hands-on experiments and don't mind working with high-voltage equipment. Chinese universities excel in this field—Tsinghua University, Xi'an Jiaotong University, Huazhong University of Science and Technology, and North China Electric Power University have strong labs and industry-university partnerships, offering exposure to real UHV projects and smart grid initiatives. If you're into 'big engineering,' this field provides plenty of practical opportunities.

Major prospects

这个领域目前最火的方向是特高压输电和智能电网。中国已经建成了全球规模最大的特高压交直流电网，把西部的水电、风电、光伏电送到东部负荷中心，这中间需要大量高电压技术人才来保证设备可靠运行。另外，新能源并网（比如海上风电、沙漠光伏）也带来新的挑战——电压波动、谐波、绝缘老化等问题都需要专业解决。 对于国际学生来说，回国后可以参与本国电网升级或中国援建的电力项目（比如一带一路沿线国家），也可以留在中国的电力设备外企（如ABB、西门子）或本土巨头（如特变电工、许继集团）。这个专业的技术通用性很强，全球都缺懂高压的人才。

Career prospects

毕业后出路很明确： - 电网公司：国家电网、南方电网的省公司或研究院，做高压设备运维、试验或规划。 - 电力设计院：比如中国电建、中国能建下属的设计院，做变电站、输电线路设计。 - 设备制造企业：像特变电工、西电集团、平高电气，或者外企如ABB、西门子，做研发、试验或技术支持。 - 科研院所：比如中国电力科学研究院，或者高校实验室，继续读博做研究。 岗位主要有高压试验工程师、绝缘设计工程师、电力系统运行维护工程师、研发工程师。薪资方面，在中国硕士应届生起薪大概15-25万人民币/年（视城市和单位而定），有3-5年经验后可达30万以上。国际学生如果留在中国工作，通常需要掌握基本中文，但很多外企和合资公司对英语友好。
