10 Environmental information
10.1 Sulphur Hexafluoride SF
6
The cubicles of the cpg.1 system are designed as a hermetically
sealed pressure system containing sulphur hexafluoride (SF
6
).
SF
6
is included in the Kyoto Protocol list of greenhouse
gases. SF
6
has a GWP ( Global Warming Potential ) of
22 200 units. (TAR, IPCC 2001).
At the end of the product's life, the SF
6
contained in it must
be recovered for processing and recycling, to prevent it being
released into the atmosphere. Extracting and handling of SF
6
must be carried out by qualified personnel, using a sealed
piercing system.
For the usage and handling of the SF
6
, the indications listed in
IEC 62271-303 must be followed.
10.2 Recyclability
The management and treatment of the rest of materials
must be carried out in accordance with the country’s current
legislation.
The materials that make up the cubicle (bases and front,
gas tank, busbar disconnector/grounding disconnector and
driving mechanisms) can be recycled. For further information,
please contact Ormazabal.
The bushings contain copper components which are difficult
to separate from the resin. Therefore, these are treated as inert
industrial waste together with the plastics.
SF
6
gas is not considered as waste, however Ormazabal
extracts the SF
6
from the cubicles at the end of their service
life, sends it for analysis and re-uses it if it retains its defined
characteristics.
