All economic activities that affect the environment should be submitted to environmental licensing, being mandatory throughout the Brazilian territory. The National Environment Policy (PNMA) and National Solid Waste Policy (PNRS), established by Law No. 12,305/2010 and regulated by Decree No. 7,404/2010, establishes the need for compliance with socio-environmental principles through prevention and precaution, eco-efficiency, among others. Considering that most of the electrical equipment – e.g. power transformers, capacitor banks, circuit breakers, reactors, switches, Gas-insullated Switchgear - present in the plant of the electricity distribution companies use mineral oil insulating, Sulfur Hexafluoride (SF 6 ) and non-biodegradable solid materials, and given the complexity and extension national electric grid, it is evident the concerning with the methods of protection to the environment. So the appropriate treatment and disposal of waste, generated by energetic companies, brings benefits such as the improvement of socio-environmental indicators of the company and provides control and monitoring of its assets. Along with the usage of sustainable materials in high voltage equipments could provide a greater electrical equipment lifespan and shorten time and maintenance costs associated to. Therefore, this prospective review, initially describes the use of sustainable of non-regenerative insulating system in electrical equipment used by Brazilian energetic companies and presents a conclusion in order to demonstrate improvement in maintenance actions of electric energy assets in compliance with national sustainability policies.
