肘型避雷器 200A Elbow MOV Arrester

Eaton（Cooper）美标肘型避雷器 200A Elbow MOV Arrester (32380 Series）

Eaton combines metal(zinc) oxide varistor technology in a premolded rubber elbow to provide overvoltage system protection in an insulated, fully shielded, submersible, deadfront device with its Cooper Power^TM series metal oxide varistor elbow(M.O.VE.) surge arrester.

The arrester housing interface conforms to lEEE Std 386^TM-2006 standard-Separable Insulated Connector Systems. The arrester housing is molded of EPDM insulating rubber, which provides deadfront safety in a small, clampstick operable unit.

M.O.VE arresters are used on underground 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 200A loadbreak interfaces that conform to lEEE Std386TM-2006 standard to limit overvoltages to acceptable levels protect equipment and extend cable life.

The rubber body is constructed of high quality precision molded peroxide-cured EPDM insulation and semi-conductive materials.

The copper alloy probe and probe retainer are connected to the MOV block stack via welded flexible tin-plated copper leads. This ensures that the column cannot be damaged during installation and that a reliable current path to the MOV blocks is maintained. The disk column is composed of MOV disks bonded together with high-conductivity, silver-loaded epoxy to yield the most reliable electrical connection and eliminate air voids. The #4 AWG flexible copper ground lead, which reliably carries current to ground during voltage surges, is attached to the housing by a brass magneformed end cap. The brass end cap provides a tight, weatherproof seal.
