Disc insulator 10KV/20/32/132KV porcelain insulator

An insulator is a material or method that restricts the transfer of either heat or the case of heat, thermal insulators work by reducing the rate heat can travel through a space. Generally, they use specific material and will keep hast-carrying matter from moving, In the case of electricity, electrical insultors confine an electric current to a designated path. They tyically work by using a material with many outer eletionsa condition that will cause low electrical conductivity.
