Silicone rubber has been implemented in the utility market for more than 25 years and is becoming the polymeric material of choice for application at distribution, transmission and substation. Balestro chose silicone for its exceptional performance durability and insulation characteristics. Inherent to silicone are its ability to maintain its natural hydrophobicity over its service life plus maintain stability against high temperatures, flashovers and UV radiation.

Balestro silicone cutouts weigh less than of their porcelain counterparts. The insulator body is a one-piece silicone injection mold that encapsulates the upper and lower mounting provision as well the center-mounting pin. This design eliminates the potential for moisture ingress and increases the rigidity as well as decreases the flexion on the silicone body under interruption and re-fusing. All Balestro Cutout meet or exceed applicable test requeriments including IEEE C 37.41-2000, ANSI C 37.42-1996 and IEC 60.282/05.
