Main features of the product
Using dry air as insulation medium, environmentally friendly
The core unit (gas box) adopts 304 stainless steel and laser static sealing welding technology, making its protection level as high as IP67
The isolation switch and grounding switch only have one operating handle, so there is no need to identify or worry about errors
The connection method of the main busbar can be selected as top expansion or side expansion, which is easy to expand
Complete logic and mechanical interlocking system, integrated with mechanical switch position indication and panel simulation diagram
Fully insulated, fully shielded, plug-in cable, maintenance free, easy to install
Complete and reliable "five prevention" interlocking and operating mechanism with dual anti misoperation system
