Outdoor Vacuum Circuit Breaker FAQ
Q: How does an Outdoor Vacuum Circuit Breaker differ from an SF6 type?
A: The primary difference lies in the arc quenching medium. A Vacuum Circuit Breaker uses a high-vacuum interrupter, making it more environmentally friendly as it contains no greenhouse gases. It offers excellent dielectric recovery, requires less maintenance, and is generally more compact. Lugao's designs leverage vacuum technology for a cleaner and safer grid solution.
Q: What is the typical maintenance interval for an Outdoor VCB?
A: Modern Outdoor Vacuum Circuit Breakers, like those from Lugao, are designed for minimal maintenance. The sealed vacuum interrupter is maintenance-free for life. Routine checks, recommended every 3-5 years or per operational cycles, primarily involve mechanical components, insulation checks, and secondary circuit testing. Our digital monitoring features significantly extend these intervals by providing health diagnostics.
Q: Can these breakers be retrofitted into older switchgear?
A: Yes, in many cases. Lugao engineers Outdoor Vacuum Circuit Breakers with a focus on standardized footprints and interoperable dimensions to facilitate replacement and retrofit projects. However, a full compatibility assessment of the existing switchgear cell, busbar system, and protection relays is always necessary before installation.
Staying ahead in power distribution means partnering with innovators. The latest Outdoor Vacuum Circuit Breaker technology from Lugao Electric delivers the intelligence, robustness, and efficiency required for the future grid.
