1. ZW32 is a three-phase structure, each phase is combined of vacuum interrupter and operation insulator in the sealed pole. The permanent magnet mechanism adopts three-phase linkage, mounted in a sealed stainless-steel shell. Enclosure is with IP67.
2.The magnetic mechanism is with interlock function to keep the operation of mechanism in good condition and keep the ON/OFF condition by electromagnetic lock. Tripping is done by a anti power of coils from a anti current .The operation power is supplied by the capacitor in the Recloser Control.
3.ZW32 Recloser is with manual tripping function to keep the Recloser at ON/OFF positions by handle the hand shank out of the shell which is with indication ON/OFF ,it is easy for operator to watch conditions from the ground., the Recloser's ON/OFF can be inspected by state of auxiliary switch .by current transformer of which rate is 600/1A(100-500/1A optional) CT to meter current and protect the overcurrent .The main insulated pole is poly insulating material which is anti-ultraviolet rays. The silicon rubber tube of outlet is with high creep distance. The terminal kit to connect with connector and overhead line.
