It is a high-voltage substation used to step down voltage from transmission levels to distribution levels, typically converting 220 kV to 110 kV, 66 kV, or lower voltages. The effectiveness of a 220 kV substation depends heavily on the precision and clarity of its layout drawing.

kv substation layout drawing Introduction A 220 kV substation plays a vital role in the electrical power transmission network. It is a high-voltage substation used to step down voltage from transmission levels to distribution levels, typically converting 220 kV to 110 kV, 66 kV, or lower voltages.
