Oxidised silicon is quartz, i.e. silicon dioxide, the main component of glass. This happens since the “valence” band containing the highest energy electrons is complete, and a large energy gap separates this band from the next band above it. There is always some voltage that provides electrons adequate energy to be excited into this band. As soon as this voltage is exceeded the material ceases becoming an insulator, and charge starts to pass through it. On the other hand, it is generally accompanied by physical or chemical modifications that permanently degrade the material’s insulating properties.

Pin insulators are commonly utilized in distribution and short transmission lines for voltages up to 33KV. Shackle and remain insulators on the other hand are used in low voltage systems. The insulators or line insulators are utilised in overhead transmission and distribution lines.
