Product Overview

The XJG-14 spring operating mechanism is a dedicated load mechanism for XJ Delishier's T cabinet, suitable for operating circuit breakers in 12/24kV GISELA/MINEX SF₆ gas-insulated ring main units or other indoor/outdoor vacuum circuit breakers with equivalent closing power. Its performance complies with GB1984 "AC High-voltage Circuit Breakers" and the "Technical Requirements" of this product. The mechanism offers both electric and manual button operation for closing/opening. The manual operating mechanism has manual closing/opening functions. The electric operating mechanism has motor-driven closing/opening functions. The mechanism features smooth operation, compact structure, high closing power, and long lifespan.

Performance Features
