Abstract：Thermosets are widely used for insulation protection of electrical equipment and play notable roles in advanced electrical systems for their excellent electrical properties, thermal stability and mechanical properties. Conventional electrical insulating thermosets are processed complicatedly and unfriendly to environment during manufacture, operation, maintenance and recycling. In recent years, the advancement of green power grids and the promotion of sustainable development have spurred considerable interest in environmental-friendly electrical insulating thermosets. Green synthesis technology and design of recyclable molecular structure are emerging technologies for preparing environmental-friendly electrical insulating thermosets. This paper reviewed the advanced research for environmental-friendly electrical insulating thermosets and mainly introduced bio-based electrical insulating thermosets, green synthesis technology of electrical insulating thermosets, as well as electrical insulating thermosets based on unstable covalent structures. Finally, the future directions in the field of electrical insulating thermosets were proposed.
