The invention relates to a bypass flexible high-voltage power cable insulation residual life evaluation method and an experiment platform, and solves the problem that the bypass flexible high-voltage power cable insulation residual life evaluation cannot be realized in the prior art. The butt method comprises the following steps: preparing a cable sample, carrying out an accelerated aging experiment on a sheet-shaped sample and a short cable sample, determining a cable insulation residual life evaluation equation, and evaluating the insulation residual life of the bypass flexible high-voltage power cable in use. The experiment platform comprises an accelerated aging experiment table and a measurement experiment table. The method comprises the following steps: sampling a cable, accelerating aging, determining the relationship among the cable insulation life, the aging temperature and the conductive current, obtaining an evaluation equation, measuring the cable load current, the conductive current and the ambie
