Typical uses, ratings, approvals 8DJH switchgear is a factory-assembled, type-tested, 3-pole metal-enclosed single-busbar switchgear for indoor installation. 8DJH switchgear is used in public and industrial energy systems of the secondary distribution level, e.g. in • Local ring-main units, customer transfer substations and switching substations of power supply and public utilities • Wind power and solar plants, hydroelectric power plants • Water and sewage treatment plants • Airports, railway stations, underground railway stations • Open-cast mining facilities • High-rise buildings....

Requirements Features 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...
