Servicing
42 End of service life
Service life Under normal operating conditions, the expected service life of gas-insulated switchgear 8DA10
is at least 35 years, probably 40 to 50 years, taking the tightness of the enclosed high-voltage
parts into account. The service life is limited by the maximum number of operating cycles of the
switching devices installed:
• For circuit-breakers, according to the (endurance) class defined in IEC 62271-100
• For three-position disconnectors and earthing switches, according to the (endurance) class
defined in IEC 62271-102.
The maximum permissible number of operating cycles of the circuit-breakers installed is
10000 (optionally 30000). The current number of operating cycles can be checked on the
mechanical operations counter.
SF
6
gas The equipment contains the fluorinated greenhouse gas SF
6
registered by the Kyoto Protocol
with a global warming potential (GWP) of 22 800
2
.
Recycling The switchgear is an environmentally compatible product.
The components of the switchgear can be recycled in an environmentally compatible way by
dismantling into sorted scrap and residual mixed scrap.
After evacuating the SF
6
gas, the switchgear mainly consists of the following materials:
• Steel
• Copper
•Aluminum
•Cast resin
• Fiber-reinforced plastics
• Rubber materials
• Ceramic materials
•Lubricants
The switchgear can be recycled in ecological manner in compliance with existing legislation.
Auxiliary devices such as short-circuit indicators have to be recycled as electronic scrap.
Any existing batteries have to be recycled professionally.
As delivered by Siemens, the switchgear does not contain hazardous materials as per the
Hazardous Material Regulations applicable in the Federal Republic of Germany. For operation
in other countries, the locally applicable laws and regulations must be observed.
For further information, please contact the Siemens Service Hotline.

CAUTION
Danger of suffocation and risk of environmental damages
A high concentration of SF
6
in the air can cause suffocation.
Larger amounts of SF
6
in the atmosphere can cause environmental damages.
➭SF
6
has to be reclaimed and must not be released into the atmosphere.
➭ For use and handling of SF
6
, IEC 62271-4:
High-voltage switchgear and controlgear - Part 4:
Use and handling of sulphur hexafluoride (SF
6
) has to be observed.
