Transmission and transformation equipment
Transmission and transformation of basic electrical equipment, including the main wire, transformers, switchgear, high voltage insulators, etc.
Because of the need to change the current in the process of transmission, so the current transfer is called power transmission.
High voltage has a very high risk, and the target electrical appliances do not need such a high voltage, which needs to reduce the voltage through the transformer
Power transmission and transformation of the protection of the main transformer, relay protection devices, lightning arrester, etc..
