Environmental independence Hermetically tight, welded switchgear vessels made of stainless steel as well as single-pole solid insulation make the parts of the primary circuit under high voltage of 8DJH switchgear • Insensitive to certain aggressive ambient conditions, such as: – Saline air – Air humidity – Dust – Condensation • Tight to ingress of foreign objects, such as: – Dust – Pollution – Small animals – Humidity. Compact design Thanks to the use of SF6 insulation, compact dimensions are possible. Thus: • Existing switchgear rooms and substation rooms can be used effectively • New constructions cost little • Costly city-area space is saved. Maintenance-free design Switchgear vessels 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 62271-200 (sealed pressure system) • Installation, operation, extension and replacement without SF6 gas work • Reduced operating costs • Cost-efficient investment • No maintenance cycles.
