Advantages and disadvantages of prefabricated substations and box type substations

Prefabricated substations (i.e. box type substations) and civil substations (transformer and distribution rooms) each have their own characteristics in terms of cost, reliability, and construction. The following is a specific comparison:

cost comparison

-Prefabricated substation: The equipment itself has a lower price, but the operation and maintenance costs are higher; The cost of cables may be lower due to dispersed layout.  

-Civil engineering substation: The cost of civil engineering investment is high, but the operation and maintenance expenses are relatively low; The amount of cables used is large, and the cost may be higher due to centralized layout.  

Reliability comparison

-Prefabricated substation: high integration, mature technology, and overall high reliability.  

-Civil engineering substation: built inside buildings for higher reliability.  

construction comparison

-Prefabricated substation: simple on-site construction, only requiring foundation and cable trench.  

-Civil engineering substation: It is necessary to redo the civil engineering, and the construction is complex.  

Operation and maintenance comparison

-Prefabricated substation: harsh operating environment, inconvenient maintenance.  

-Civil engineering substation: environmentally friendly and easy to operate.  

environmental impact

-Prefabricated substation: occupies ground space and may affect the landscape.  

-Civil engineering substation: has little impact on the environment.
