Porcelain insulator is designed to be assembled together to be insulator strings (also called strain insulators), which can divide into Ball & Socket Type and Clevis & Tongue Type. This structure enables them form the insulator string by fitting into themselves one another as per voltage requirement. A ceramic suspension insulator set complete with the fittings is used to carry a line conductor or conductors at its lower end. The top of the ceramic suspension insulator is fixed to the crossarm of the tower.
