QINGDAO RAILWAY 110KV PREFABRICATED SUBSTATION
Prefabricated substations are prefabricated in the factory, with different modules produced and installed synchronously. Factory prefabrication is carried out synchronously with on-site civil engineering, and on-site installation and commissioning take about 45 days. The entire station construction period is 3-4 months. The overall investment of the station is 12.4% less than that of the civil construction mode.
