Product characteristics
Vacuum circuit breaker or load switch + fuse (combined electrical appliancetechnical solution can be used on the high voltage side of Huashi box. The electricalcharacteristics of the combined electrical structure is that when any phase fuse isblown, the load switch will be guaranteed to trip and cut off the power supply, and themain switch can be closed after replacing the fuse.
The vacuum circuit breaker or load switch + fuse (combination electrical appliance)used in the high voltage side is set up mechanical interlock to prevent misoperation,and the vacuum circuit breaker or load switch + fuse (combination electricalappliance) is set up signal transmission signal to facilitate the background real-timemonitoring of its operating status and remote control function.

Say goodbye to the long construction cycles and uncertain risks of traditional power generation. We offer prefabricated, modularly designed, and one-stop delivery solutions for prefabricated substations, shortening project construction time by 60% and ensuring faster, more stable, and smarter power supply.
From design to factory commissioning and delivery, the entire substation can be completed in just 4-6 weeks.
Onsite, only foundation leveling, hoisting, and cable connection are required, and power supply is available within a week.
Winning prime time for grid connection of new energy power plants, enterprise expansion, and emergency power supply.
Full-condition simulation pre-commissioning: Over 100 tests, including protection transmission and communication point-to-point testing, are completed in-plant to ensure error-free commissioning.
Military-grade protective enclosure: High-strength steel structure, C5-level corrosion protection (hot-dip galvanizing), IP54 protection rating, and resistance to salt spray, wind, sand, and condensation.
Intelligent internal environment: Industrial air conditioning, fans, electric heaters, and gas fire protection systems work together to maintain a constant temperature and humidity inside the system.
