Isolation Self-Locking Pull Rod is a key safety operating component specially designed for ZW32 Circuit Breakers, mainly used in the isolating switch mechanism of outdoor high-voltage vacuum circuit breakers. As an important part of Vacuum Circuit Breaker Parts, it realizes reliable self-locking and positioning during the opening and closing of the isolating switch, effectively preventing misoperation and accidental movement, ensuring stable and safe equipment operation. Made of high-strength engineering plastic and metal alloy with precision machining, it features high mechanical strength, good toughness, stable self-locking performance, strong wear resistance and long service life. With standard structural dimensions and high compatibility, it fits perfectly with the isolating mechanism and is easy to install and replace. As an essential part of Circuit Breaker Spares and a safety-critical type of Electrical Components, it greatly improves operational safety and reliability, widely used in power distribution networks, industrial power systems and substation equipment to maintain stable and secure breaker operation.
