What are the common outdoor substation technologies？

Outdoor substation technologies are those involved in the design, construction and operation of substations used in outdoor 

environments. The following are some common outdoor substation technologies:

Overhead transmission lines: outdoor substations are usually connected to high-voltage overhead transmission lines, and the

 design and layout of transmission lines is one of the keys to outdoor substation technology. This includes the direction of the

 transmission line, the type and arrangement of the tower, line insulators and so on.

Transformer: oil-immersed or dry-type transformers are often used in outdoor substations. Oil-immersed transformers have

 higher load adaptability and better heat dissipation performance, while dry-type transformers have lower maintenance costs

 and better environmental adaptability.

Switchgear: Switchgear is commonly used in outdoor substations to control the connection and disconnection of circuits. 

Switchgear includes circuit breakers, disconnecting switches, load switches and so on.

Lightning arrester and insulator: In order to protect substation equipment from lightning strikes and insulation breakdown,

 lightning arrester and insulator are often installed in substations. Lightning arresters are used to eliminate overvoltage, 

while insulators are used to insulate equipment and support transmission lines.

Monitoring and Protecting Equipment: Outdoor substations need to monitor and protect the operational status and safety 

of equipment. This includes the use of monitoring devices for real-time monitoring of parameters such as current, voltage,

 temperature, etc., and the use of protection devices to protect against anomalies by timely disconnection.

Monitoring and communication systems: In order to realize remote monitoring and control of outdoor substations, monitoring

 and communication systems are often used. These systems, through sensors and remote communication devices, can monitor 

the operating conditions of the substation in real time, and communicate and comman.
