Grounding Causes of Cable Lines and the Principles of Incident HandlingOur 220 kV substation is located far from the urban center in a remote area, surrounded primarily by industrial zones such as Lanshan, Hebin, and Tasha Industrial Parks. Major high-load consumers in these zones—including silicon carbide, ferroalloy, and calcium carbide plants—account for approximately 83.87% of our bureau’s total load. The substation operates at voltage levels of 220 kV, 110 kV, and 35 kV.The 35 kV low-voltage side mainly supplies feeders to ferroalloy and silicon carbide plantsFelix Spark10/21/2025 -
