SF6 Gas and Gas Reclaiming
|
SF6 Gas is
considered to be the best dielectric medium for EHV Switchgears
upto 400 KV because of its properties, We at OVAC, can
store, supply, reclaim from poles / empty cylinders, purify
SF6 gas, with the help of our imported Haskel make portable reclaiming
machines.
SF6 Gas is available in Standard Capacity Cylinders of 11kg,
25kg, 36kg, and 50kg. Under NTP, SF6 is in gaseous form. It
is filled in cylinder at 0oC to 5oC. Hence under
completely filled cylinder, Bulk of the cylinder is filled
with liquid SF6. As gas is used from new cylinder, liquid
gas level drops in side cylinder, which ultimately reduces
weight
and pressure of gas. At certain stage the cylinder is declared
as empty where as 1/2 to 1 kg of gas is still
there in the cylinder.
With the help of HASKEL Model 52089 SF6 gas can be
efficiently reclaimed from such cylinders as well as SF6 breaker
poles and reused after filtering. The unit requires 4-10 bar
compressed air supply to generate pressure upto 35 bar and
can empty cylinder 260 torr vacuum.
We also have range of imported and indigenously normally developed
filters for purification of Gas.
