performance of the system.
1.
APPLICATION
Stations are designed for
thermal vacuum degassing of lubrication and
insulating oils whose viscosity at temperature
50 C does not exceed 70 cSt to remove gases,
water and gases.
Stations are used for
mounting, repairing and operating high-voltage
oil equipment with voltage up to 1150 kV( power
transformers, high-voltage switches etc.)
The machine complies with
number 4 category placement and climatic design
UHL as per GOST 15 150-69.
Operating conditions:
-ambient temperature 283 to
308 K( +10 to 35)C;
-atmospheric pressure 84 to
106,7 kPa ( 630 to 800 mm.Hg);
- altitude above sea level
2000 m.;
- ex-proof premises.

Note
- *
Parameters stated in the table
can be reached within 1 processing cycle
under the following
characteristics of initial oil:
-
bulk gas content no more than
10,5%;
-
mass moisture content no more
than
50
g/t.
**
The station can be custom
manufactured with filtration degree 1mcm of
