Cooper Power Systems proven POSI-BREAK design has expanded from protection of loadbreak separable connector systems to the arrester market. Cooper Power Systems has designed an elbow arrester, the POSI-BREAK elbow arrester, which increases reliability while protecting your operators. POSI-BREAK elbow arresters address the partial vacuum flashover that occurs when an elbow or cap is separated from an energized bushing. Our POSI-BREAK elbow arrester offers improved dielectric strength and minimizes susceptibility to partial vacuum flashovers while increased tolerance to contamination and high altitude increases its reliability.
