FZW32-40.5/T1250-25 outdoor high voltage isolate vacuum switch is a new generation of high voltage electrical equipment developed by both home and overseas advanced technology. Each of the technical performance have reach the standard of GB3804 and IEC.
They are designed for the construction and reform of urban and rural grid. The bottom of the product has adopted stainless steel and galvanized carbon steel with ultraviolet-proof coating material, to make sure it's normal outdoor operation. Each stainless steel component can ensure it's durability, stability, water-proof and salt fog against ability.
It has characteristic of small size, light weight, good appearance, easy operation, strong breaking ability, long electrical life maintenance free and obvious fracture. It can adopt manual single-pole operation and also electric, distance operation.
