6 Requirements Features Safety Environmental independence The enclosed high-voltage part of 8D and 8DB switchgear is suitable for applications under aggressive ambient conditions, such as: Saline air ir humidity Dust Condensation. It is tight to ingress of foreign objects, such as: Dust Pollution Small animals. The application is independent of the site altitude. Compact design Thanks to the use of SF 6 insulation, compact dimensions are possible. Thus: Existing switchgear rooms can be used effectively New constructions cost little Costly city-area space is saved. Maintenance-free design Switchgear housings designed as sealed pressure systems, maintenance-free switching devices and enclosed cable plugs ensure: Maximum supply reliability Personnel safety Sealed-for-life design according to IEC (sealed pressure system) Reduced operating costs Cost-efficient investment. Innovation The use of digital secondary systems and combined protection and control devices ensures Clear integration in process control systems Flexible and highly simplified adaptation to new system conditions and thus to cost-efficient operation. Service life Under normal operating conditions, the expected service life of gas-insulated switchgear 8D and 8DB is at least 35 years, probably 0 to 50 years, taking the tightness of the enclosed high-voltage part into account.

60 Standards Standards, specifications, guidelines Type of service location The switchgear can be used as indoor installation according to IEC 6936 (Power installations exceeding kv C) and VDE 00 Outside lockable electrical service locations at places which are not accessible to the public. Enclosures of switchgear can only be removed with tools In lockable electrical service locations. lockable electrical service location is a place outdoors or indoors that is reserved exclusively for housing electrical equipment and which is kept under lock and key. ccess is restricted to authorized personnel and persons who have been properly instructed in electrical engineering. Untrained or unskilled persons may only enter under the supervision of authorized personnel or properly instructed persons. Terms Make-proof earthing switches are earthing switches with short-circuit making capacity according to IEC 67-0 and VDE / EN Dielectric strength The dielectric strength is verified by testing the switchgear with rated values of short-duration power-frequency withstand voltage and lightning impulse withstand voltage according to IEC/EN 67- / VDE 067- (see table Dielectric strength ) The rated values are referred to sea level and to normal atmospheric conditions (03 hpa, 0 C, g/m 3 humidity according to IEC 7 and VDE 0). The gas insulation at a relative gas pressure of > 50 kpa permits switchgear installation at any desired altitude above sea level without the dielectric strength being adversely affected.

61 Standards Standards, specifications, guidelines Current carrying capacity ccording to IEC or IEC 67-, VDE or VDE 067-, the rated normal current refers to the following ambient air temperatures: Maximum of -hour mean + 35 C Maximum + 0 C The current carrying capacity of the panels and busbars depends on the ambient air temperature outside the enclosure. Internal arc classifications Protection of operating personnel by means of tests for verifying the internal arc classification Internal arcing tests must be performed in accordance with IEC or VDE and IEEE Std C Definition of criteria according to IEC or VDE: Criterion Correctly secured doors and covers do not open, limited deformations are accepted Criterion No fragmentation of the enclosure, no projection of small parts above 60 g Criterion 3 No holes in accessible sides up to a height of m Criterion No ignition of indicators due to hot gases Criterion 5 The enclosure remains connected to its earthing point. Resistance to internal faults Due to the single-pole enclosure and the SF 6 insulation of the switchgear and the switching devices, the possibility of faults in SF 6 -insulated switchgear is a mere fraction of that typical of other switchgear types: There are no effects due to external influences, such as: Pollution layers Humidity Small animals and foreign objects Maloperation is practically excluded due to logical arrangement of operating elements Short-circuit-proof feeder earthing by means of the circuit-breaker. In the unlikely event of a fault within the switchgear housing, the energy conversion in the case of an internal arc fault is minor thanks to the SF 6 insulation and the shorter length of the arc, i.e. approximately only /3 compared to air. Resistance to short-circuits and earth faults Two-phase and three-phase short-circuits between the primary conductors are excluded by the single-pole primary enclosure. For installation on even and rigid concrete or steel structure (without considering building influences), the tested ground accelerations meet the following requirements: Uniform Building Code 997 (UBC) Zone California Building Code 998 (CBC) Zone International Building Code 006 (IBC) - 00 % merican Society of Civil Engineers 005 (SCE) - 00 % IEEE High required response spectrum (Figure.).
