摘　　要：本文回顾了反幂定律的发展过程,用Eyring公式对反幂定律的正确性进行了理论解释,总结了反幂定律在确定高压电缆绝缘厚度和在电缆E-t寿命曲线中的应用,给出了温度修正的电老化寿命模型,阐述了温度在高压电缆寿命设计中的重要性。The development process of the inverse power law was reviewed, and the correctness of inverse power law was theoretical explained with the Eyring equation. The application of the inverse power law in determining the thickness of high voltage cable insulation and the application in the life curves of cable were summarized. Finally, this paper presented the electrical ageing lifetime model revised by temperature and emphasized the importance of temperature in the lifetime design of high voltage cable.
