Among all the astonishing equipment found in power transmission and distribution networks, the insulator plays a vital role by providing mechanical support and electrical protection to power system. Despite of all these noteworthy facts, the breakdown of insulators owing to surface contaminants appears to be particularly fascinating in today's scientific world. Researchers provide a plethora of methods to eradicate this problem. From all method, superhydrophobic coating provide better solution for its resistance to moisture, wetness, dust and ice. This unique property of superhydrophobic coatings requires further investigation. Hence, the suggested technique achieves this purpose by preparing the eco-friendly superhydrophobic solution of PDMS (Polydimethylsiloxane) with MTMS (Methyl tri methoxy silane) composites. In this study superhydrophobic coating were prepared by using sol-gel method and spray coating technique Analysis like FTIR, surface morphology and coating thermal study were included. self-cleaning ability of superhydrophobic coating on insulator surface with contact angle (CA) was measured from 165° to 170° and sliding angle 5° to 10° confirming superhydrophobic property. Finally, in an intentionally contaminated conditions based on solid layer method of IEC60507 standards and IEC 60587 standards insulation resistance are tested using a megger instrument.
