1 Scope
1.0.1 The "Rule" prescribed the basic requirements for power plants and transformer substations newly-built project selecting (3-500) kV conductor and electrical equipment.
1.0.2 The "Rule" is suitable for power plants and transformer substations newly-built project selecting (3-500) kV conductor and electrical equipment. For expanded project and reconstructed project, it can refer to use.
1.0.3 Foreign projects will take the country of supply party or buyer into consideration. The "Rule" is referred to in combination with the physical circumstance of the project.
