The plant for preliminary drying the solid insulation «INEY»

ineyThe Plant is designed for vacuum degassing, preliminary drying and drying the solid insulation of power transformers up to    1150 kV, tanks of which are withstand residual pressure 26 Pa (0,2 mm of mercury column) during installation and repair of them.
Useing the Plant for transformers tanks which are not withstand residual pressure 26 Pа it is possible after tank strengthening.

 ParameterValue
 Quickness of gas-vapor mixture exhaust from transformer at the residual pressure  26-60 Pa, m3/s, not less than 0,4
 Residual pressure in Plant at the closed inlet fitting, Pa, not more than 2,6
 The trap surface temperature which determine by cooling mixture temperature, oС, not above than:
  •  when the useing hard carbon dioxide and acetone as refrigerant coolant
 -70
  •  when the useing liquid nitrogen as refrigerant coolant
 -160
  •  when the useing built-in cooling facility
 -70
