Rendering Where air is humid, salty or full of conductive dust, a resin-impregnated class H unit outlasts a casting. The SGB11 uses vacuum-pressure impregnation with a 180 °C insulation system, so it tolerates higher ambient temperatures and recovers from moisture ingress that would degrade other constructions.
