The　use　of　a　silicone　rubber　composite　insulator　has　become　an　important　aspect　to　ensure　the　safe　operation　of　an　electrical　power　grid.　This　study　introduces　a　preparation　method　of　a　superhydrophobic　silicone　rubber　surface　using　a　simple　preparation　process　at　low　cost　and　with　excellent　performance,　which　can　be　used　in　the　mass　production　of　silicone　rubber　composite　insulators.　In　this　study,　the　combination　of　a　compression　molding　process　and　a　template　method　was　used　to　prepare　the　product.　A　microstructure　composed　of　numerous　boat-shaped　grooves　was　constructed　on　the　surface　of　silicone　rubber.　The　modification　of　a　low　surface　energy　material　is　not　required.　The　static　contact　angle　with　water　after　the　high-temperature　treatment　exceeds　150°,　and　the　rolling　angle　is　under　10°.　Excellent　performance　has　been　observed　in　terms　of　self-cleaning　effect,　aging　resistance,　and　mechanical　and　droplet　bounce　properties.　It　has　been　shown　that　the　loss　of　superhydrophobic　properties,　due　to　the　prolonged　immersion　in　water,　can　be　restored　by　a　high　temperature　heating　process.　This　journal　is　©　The　Royal　Society　of　Chemistry.
