Polymer cross arm insulators are electrical equipment used in power transmission and distribution lines to bear mechanical load and insulation.
Polymer cross arm insulators have an effective use of a narrow corridor pressure transmission and applicable to rebuild of city power net. Polymer crossarm insulators can also reduce the tower height, saving manpower, material and financial resources. Silicone rubber crossarm insulator has a superior performance than porcelain insulator. The type code is normally FS Type.
