| Distribution Class Arresters for Underground Systems (Elbow and Parking Stand Arresters)
For underground distribution systems having deadfront equipment, Cooper Power Systems has a wide range of arresters for such
applications. Elbow and Parking Stand arrester styles are available in a gapless or gapped MOV (VariGAP®) designs. All of these
arresters come in a molded EPDM rubber housing.
Elbow Arresters
Elbow Arresters are used on undergound systems in pad-mounted transformer and entry cabinets, vaults, switching enclosures
and other installations to provide shielded deadfront arrester protection. They are designed for use with 200 A loadbreak
bushings or interfaces that conform to IEEE Standard 386™. These arresters limit overvoltages to acceptable levels and extend the life of cable and other connected equipment.
Cooper Power Systems elbow arresters are available in 15, 25 or 35 kV class interface sizes per IEEE Standard 386. Arrester ratings are available from 3 to 27 kV.
For more information on VariGAP elbow arresters, see Catalog Section 235-55
For more information on gapless M.O.V.E.™ elbow arresters, see Catalog Section 235-65
Parking Stand Arresters
Parking Stand arresters combine arrester technology with a premolded rubber insulated standoff bushing. They are designed to be
used with 200 A loadbreak elbows or interfaces conforming to ANSI/IEEE Standard 386. Parking Stand arresters provide an
economical means of overvoltage protection for energized but parked open point cable runs.
Cooper Power Systems Stand arresters are available in 15 or 25 kV class interface sizes. Arrester ratings are available from 3 to 21 kV.
