With the rapid development of productivity, the demand for power supply is increasing dramatically. As a safe and reliable way of power transmission, the investment scale of power cable engineering is increasing. This paper innovatively puts forward a calculation method of cable line engineering’s comprehensive cost index, which accurately reflects the variations in cable line engineering’s comprehensive costs with different voltage levels and various construction technologies within a certain period of time. Furthermore, it explores cable line engineering’s comprehensive cost index and the correlation between macroeconomic indicators. The correlation coefficients between research objects are calculated. The research shows that there is a strong correlation between the law of power cable engineering cost hole and macroeconomic index, and the fluctuation of raw material price index also has a profound impact on the cost.
