Abstract: [Introduction] Cable terminal tower is the development trend of converting the overhead transmission line to electric cable line in power grid construction. [Method] Based on the current status of cable terminal construction, this paper proposed a new anti-beam structure of cable terminal platform, mainly studied the optimal arrangement of the platform structure and analyzes in detail of the new structure. The strength, rigidity and stability of the main force components of the calibration platform were analyzed. The influence of the platform structure on the force of the tower was analyzed, and the details were discussed. [Result] The results show that using a simplified structure of the anti-beam structure using simplified support structure in a range of span and the terminal head and the arrester base on the main beam, the size and spacing of the secondary beams can be properly arranged to ensure the strength and rigidity of the platform structure and save the amount of steel. Form a standardized platform design, and combine the existing terminal towers with diverse conditions can realize "general-purpose" through the "terminal tower + standard design platform" model. [Conclusion] Our data widely summarizes the experiences in Guangdong province, this work provides some guidance for different areas, voltage classes and tower models.
