The utility model relates to a turning basin-type insulator, which comprises basin-shaped epoxy resin and central conductive rods arranged in the epoxy resin, wherein each central conductive rod comprises a connecting plate and rod bodies which are arranged at two opposite ends on two sides of the connecting plate and vertical to the connecting plate; and a flange on the periphery of the epoxy resin is made by metal. The central conductive rods are Z-shaped, then conductive rods linked with the central conductive rods do not need to be turned again, the mass standardized production of the conductive rods is facilitated, the component processing cycle can be shortened, the cost is saved, and the modular assembly is easier; and the metal flange on the periphery of the epoxy resin enables the uniform distribution of the electric field inside the basin-type insulator, the design requirements are better met, and the service life of the basin-type insulator can be prolonged with the adoption of the metal flange.
