Abstract
Un aparato eléctrico aislado por gas que comprende un recinto conductor exterior, un electrodo interior dispuesto dentro de dicho recinto exterior y espaciado del mismo, medios para soportar con posibilidad de aislamiento dicho electrodo interior dentro de dicho recinto exterior, un gas aislante dispuesto dentro de dicho recinto exterior y que aísla eléctricamente dicho electrodo interior respecto de dicho recinto exterior, un vapor disolvente que comprende tricloroetileno entremezclado con dicho gas aislante dentro de dicho recinto exterior, y un revestimiento aislante seco, relativamente duro al principio, dispuesto sobre áreas superficiales seleccionadas de dicho aparato eléctrico, teniendo dicho revestimiento aislante una superficie del mismo expuesta a dicho gas aislante y a dicho vapor disolvente comprendiendo dicho revestimiento aislante un componente aglutinante químicamente inerte frente a dicho gas aislante y dicho vapor disolvente, siendo dicho componente aglutinante un vinilo seleccionado dentro del grupo que consta de cloruro de vinilo, copolímeros de cloruro de vinilo-acetato de vinilo, copolímeros de etileno-acetato de vinilo y mezclas de los mismos, y un componente activo que interactúa con dicho vapor disolvente para volverse pegajoso después, siendo dicho componente activo una resina fenólica, siendo de aproximadamente 1:0,3 a 5,0 la relación de dicho componente aglutinante a dicho componente activo, volviéndose pegajoso dicho revestimiento aislante en la superficie del mismo, después de su exposición a dicho vapor disolvente, para atrapar partículas contaminantes, pero manteniendo su posición espacial sobre dichas áreas superficiales seleccionadas.
