The invention discloses a high-voltage suspension optical fiber composite insulated column. The high-voltage suspension optical fiber composite insulated column comprises composite insulated column bodies, the length of each composite insulated column body is smaller than or equal to 9 m, the two composite insulated column bodies are connected through a connecting piece, and a polarization maintaining optical fiber is arranged in the composite insulated column bodies. The connecting piece is formed by flanges, a connecting sleeve and a fixing sleeve, the flanges are arranged on the end portions of the composite insulated column bodies, and the flanges are connected to the connecting sleeve in an articulated manner. Generally, the high-voltage suspension optical fiber composite insulated column is advantaged in that the insulated column is simple in structure and convenient to produce and manufacture, the transportation difficulty of the high-voltage suspension optical fiber composite insulated column can be effectively reduced, the usage cost is reduced, the problem that the high-voltage suspension optical fiber composite insulated column is hard to transport is effectively solved, and the high-voltage suspension optical fiber composite insulated column has an extremely-high application value.
