The invention discloses a high-voltage wire cutting machining platform. The high-voltage wire cutting machining platform comprises a wire bearing slot body and cutting mechanisms. The wire bearing slot body is in a long strip shape. A length marking ruler is arranged on the outer surface of the wire bearing slot body and parallel to the wire bearing slot body. The wire bearing slot body is erected on two or more support frames. The cutting mechanisms are fixed to the support frames. The cutting mechanisms are located on the positions, opposite to one end of the wire bearing slot body, of the support frames. By the adoption of the high-voltage wire cutting machining platform, the standard distribution room building requirement can be met, the convenient distribution room assembly in the late period is guaranteed, construction processes are unified, the consumption of wires is reduced, the high-altitude operating time is reduced, the labor intensity is lowered, the working efficiency is improved, distribution room construction is promoted and converted into mechanization from artificialization, all related high-voltage wires cut through the platform are unified in size, and all the construction processes are unified and standard.
