Cable support and cable installation method

The invention belongs to the technical field of power grid construction, and discloses a cable support and a cable installation method. The cable support comprises a stand column, a supporting frame and a clamping mechanism. The stand column is configured to be fixed to an installation position. The supporting frame is used for supporting a cable, the supporting frame is connected to the stand column, and the supporting frame can slide in the height direction of the stand column and is positioned on the stand column; the clamping mechanism comprises a clamping arm, the clamping arm is connected to the supporting frame in a sliding mode, and the clamping arm can clamp and fix the cable to the supporting frame. According to the cable support, the mounting height can be adjusted according to the position of a cable, the adjusting precision is high, the mounting efficiency is high, the cable can be limited, the cable is prevented from being abraded or sliding off, and the safety is improved. 本发明属于电网施工技术领域，公开了一种线缆
