The invention discloses a load switching method for a flexible cable between adjacent strain towers. The invention discloses a load switching method based on a reusable flexible cable, and relates to the field of power line construction methods. In the process of lap joint of a newly-built line, existing overhead lines will be bridged, at present, hard cables are often adopted for load transfer, but the hard cables are strict in bending radius requirement, cannot be curled and wound and unwound at will, are mostly used for a single time and are low in repeated utilization rate. The method comprises the following steps: selecting a flexible cable which can be repeatedly used; manufacturing a cable terminal; erecting a flexible cable; short-time power failure is carried out, and the drainage wire of the first strain tower is dismounted and connected with the flexible cable; disassembling a second strain tower drainage wire and connecting the second strain tower drainage wire with the other end of the flexible c
