Designed by GRENO (XIAMEN) SWITCHGEAR CO., LTD., SF6 load break switches are perfect for switching circuits with currents up to 630 A in 6 kV, 10 kV, and 20 kV/24kV/50 Hz three-phase A.C. networks.
Introducing our latest innovation from GRENO (XIAMEN) SWITCHGEAR CO., LTD., the SF6 Gas Insulated Switchgear. This switchgear is providing enhanced insulation ability for arc-extinguishing when in open status. The switchgear is filled with SF6 gas at a pressure range of 0.03Mpa~0.04Mpa, ensuring optimal performance.
One of the key advantages of our SF6 Gas Insulated Switchgear is its compact size. We have safely made the whole size smaller, allowing for easy installation and space-saving benefits.
The copper contactor used in our switchgear is made from the best material available. With more than 99.95% Cu content and a special production process, the copper contactor guarantees exceptional abrasion rigidity. We refer to this material as T2 copper.
In addition, our SF6 Gas Insulated Switchgear features an increased phased distance of 210mm. This particular design elongates the air and creepage distance, ensuring enhanced safety and performance.
Our internal contact terminals are made of permanent magnetism material, ensuring their durability and longevity. When the LBS switches to the open position, the arc naturally becomes thinner and eventually extinguishes in SF6 gas. This feature enhances the safety and efficiency of our product.
We warmly welcome any inquiries at any time. Feel free to reach out to us with your questions or requests.
