2,The standard conditions of use

1. Relative Humidity: 100%
2.  Ambient air temperature: upper limit +50 ºC, lower limit of -40 ºC.

1. SF6 gas-insulated

   1.1 SF6 gas is a kind of nontoxic, nonflammable and electrical insulating gas. It has the excellent characteristic of arc extinction.
   2. Drive pipe with large diversity
   2.1In addition to the standard ceramic drive pipe, we can also provide a variety of solutions, including rubber insulators used in the epoxy resin filling equipment.
   3. Visible open / closed status
   3.1 It is easy to see the main contact position indicator which is color-coded just standing on the ground (Green - off; red - closed). The indicator is directly connected with the main contacts of the drive shaft assembly to ensure accurate display of contact states.
   4 Quick operation
   4.1 operating mechanism with spring energy to ensure a quick closing and opening operation (less than 100milliseconds).
   5 Can realize remote control
   5.1 It is equipped with electronic controller, fit for in situ operation as well as FTU interface console operation.
   6. Rugged switch
   6.1 The switch is made of proven durable, corrosion-resistant materials (special used in warships 304L stainless steel plate)which ensures that there is a very long service life (30 years), and can be implement a series of operations.It has the ideal characteristics as a column equipment.
   7 Standard
   7.1 Each switch before leaving the factory has been filled with SF6 gas, sealed, and test according to IEC60265-1, GB40.504 standard.
