Gas-insulated, medium-voltage, metal-enclosed, arc-resistant switchgear
Medium-voltage, gas-insulated switchgear 8DJH 36 can be arranged as a node in various applications. Its modular construction and configuration flexibility set the standard, particularly at the distribution level up to 38 kV. Functions can be arranged variably - not only within a section, but also in more complex switchgear lineup layouts. 8DJH 36 switchgear is suitable for implementation into almost all designs requiring various configurations. Additionally, all individual sections and lineups can be extended optionally.
The compactness of 8DJH 36 enables effective utilization of existing switchgear rooms. Plus, new buildings can be constructed smaller because of its size, and therefore at a considerably lower cost. 8DJH 36 helps economic utilization of land, especially in urban areas, and enables the ability of points of supply to be installed closer to consumers, thus also helping to reduce energy losses.
Also, with an available outdoor enclosure, 8DJH 36 can fit into existing solar farm skid solutions with a transformer and inverter.
