The invention discloses an insulating property synergistic effect design method of environment-friendly mixed gas for electrical equipment. The method comprises the following steps: determining the volume ratio k of the environment-friendly gas under different buffer gases; configuring an environment-friendly mixed gas with a preset gas pressure p and a volume ratio of the environment-friendly gas as k, carrying out a power frequency discharge test on the environment-friendly mixed gas, comparing discharge voltage values Ub under different buffer gases, and selecting the buffer gas corresponding to the maximum value Ub as a target buffer gas Gm; wherein the environment-friendly mixed gas is composed of buffer gas and environment-friendly gas; preparing an optimized environment-friendly mixed gas composed of an environment-friendly gas and a target buffer gas Gm; wherein different gas pressures p and volume ratios k constitute different configurations (p, k) of the optimized environment-friendly mixed gas; and
