-SF6 gas insulated
SF6 is a kind of electric insulation gas. It is non-poisonous, nonflammable and has good arcing feature.
-Various bushing types
Besides standard porcelain bushings, we can also supply rubber bushings.
-Visible open and close status.
It is easy to see clearly the main contact position indicator ( greenopen, red-close). This indicator is directly connected with main contact drive shaft assembly so that it can show contact status exactly.
-Fast operation
Spring energy storage operating mechanism can quickly open and close (less than 1 second).
-Remote control
Electronic controller is equipped. Users can operate locally, or operate at master station through FTU interface.
- Firm and durable switch
The switch is made of firm, durable and anti-corrosive stainless steel so it has a long service life (30 years) and it is maintenance free. It is an ideal option for pole equipment.
-Standard
Each switch is filled with SF6 gas and is sealed. And it is tested according to IEC60265-1（1988）、GB3804-1990 before delivery.
