Gaobo Fully Sealed Insulated SF6 Ring Main Unit | 12kV High Voltage Switchgear

 

Product Introduction:

HXGN15-12/125-31.5 fully sealed fully insulated ring main unit is a high-performance SF6 gas-insulated high-voltage switchgear independently produced by Gaobo Switchgear Manufacturer. Different from traditional open-type switchgear, this equipment adopts full metal sealed and fully insulated design, with internal live parts completely isolated by high-purity SF6 gas, effectively avoiding external dust, moisture and foreign object interference.
 
With advanced integrated sealing technology, the cabinet achieves IP4X high protection level, realizing long-term stable and safe operation in complex outdoor and indoor power environments. It supports 12kV rated voltage, 125A rated current, and can withstand 20KA short-time current for 4 seconds and 50KA peak current, with excellent overload and short-circuit resistance.
 
Compliant with the latest GB/T3906-2020 national standard, the equipment has passed strict insulation and lightning impact tests. The overall structure is compact, small in size, light in weight, free of daily maintenance, low operation cost and long service life.
 
Gaobo provides professional customized services including cabinet layout, functional configuration and technical parameter adjustment to meet various urban grid renovation, industrial power distribution and engineering supporting needs.
