Both in electrical transmission and distribution lines and substations, insulators are used for suspension and support of the electrical conductors. Nowadays the porcelain or ceramic insulator become obsolete because of their fragile resistance to climatic and seismic conditions which could damage the operation of the equipment of high and medium voltage.

The current-limiting fuses are components whose main function is to protect electrical equipment such as distribution transformers, motors and capacitor banks against over currents. INAEL, manufacturer with a long experience in this product,
