An insulator is an electrical component used for the interruption of the current through the conductor. The insulator is connected to support a current carrying wire through the pole or any rigid structure. It is made of porcelain which is a great insulator. The 33Kv Pin insulator is thoroughly inspected and defects free. This electrical device is capable of providing insulation for 33 Kv supply. The device is free from deterioration due to contraction and expansion of the porcelain.
