The thermal expansion compensation optical fiber insulator comprises an insulation assembly, the insulation assembly comprises a hanging flange, an expansion joint, an extrusion part, a fixed flange and an insulator, one end of the expansion joint is connected with the hanging flange, the other end of the expansion joint is connected with the fixed flange, the extrusion part is installed on the expansion joint, and the fixed flange is connected with the insulator. And the insulator is matched with the fixed flange. According to the device, through the cooperation of the expansion joint and the extrusion piece, the complete filling of the glue solution in the optical fiber insulator core body is realized, the problems of glue solution leakage or optical fiber extrusion and the like are avoided, and the insulativity is improved. 本发明公开了一种热膨胀补偿光纤绝缘子及其使用方法包括绝缘组件，所述绝缘组件包括吊挂法兰、膨胀节、挤压件、固定法兰和绝缘子，所述膨胀节一端与所述吊挂法兰连接、另一端与所述固定法兰连接，所述挤压件安装于所述膨胀节上，所述绝缘子与所述固定法兰配合。本装置通过膨胀节与挤压件的配合，使光纤绝缘子芯体内实现胶液的完全填充，避免了胶液的泄漏或光纤挤压等问题提高了绝缘性。
