Smart Ring Main Unit
JGAIS-12 environmentally friendly gas insulated ring network switchgear
This product is a 160kW split type DC charging stack that can provide customers with reliable, safe, and fast DC charging services, meeting the charging needs of electric vehicles. The product provides multiple communication interfaces for real-time communication with station level monitoring centers or operation management centers, uploading real-time charging information. The product has a self checking function, which immediately stops charging when abnormalities or faults are detected, ensuring the personal and vehicle safety of the user during the charging process.
Product Highlights
Uses zero-pressure dry air instead of SF6 gas, with no greenhouse gas emissions, making it green and environmentally friendly.
It permanently records the time of zeroing events and the corresponding power data.
Spring energy storage, cam drive, and four-bar linkage mechanism, with a simple structure, stable performance, and long mechanical life.
The ventilation system is highly efficient and easy to maintain.
Oil-free, fully sealed, anti-condensation, explosion-proof, moisture-proof, and pillar-type structure design, requiring little or no maintenance for a long time.
