The GY-3S-40.5 series outdoor high-voltage vacuum permanentmagnet circuit breaker is a new generation of pole-mounted vacuumcircuit breaker independently developed by our company,integrating advanced domestic and international technologies. ltadopts a new design concept, incorporates various advantages, andemploys high-tech methods. This product can serve as a switch forthe main transformer output in 35kV substations or as a pole-mounted switch in distribution networks. When combined with thecompany’s controllers,it facilitates control, protectionmeasurement, and communication, making it the preferredequipment for achieving distribution network automation and small-sized substations.
Key Features:
Utilizes magnetic actuation(permanent magnet mechanism) tosignificantly reduce the number of components, reduce arcingpower, and achieve high stability and reliability without the need forregular maintenance.
Uses imported outdoor epoxy resin as external insulation materialwith light weight, a service life of over 15 years, good weatherresistance, oil-free, SF6-free, and compliance with environmentalrequirements.
Short operation time for quick fault interruption, providingconvenient and flexible protection coordination.Can be powered by solar cells or current transformers, eliminatingthe need for an external power source for electric operation.Remote control operation is achievable with a dedicated remotecontroller, enabling remote operations without the need to climbpoles.
Integrated design of high-voltage isolation switch for compactstructure,easyinstallation,and maintenance.
