How To Choose A Suitable Prefabricated Substation

Choosing a suitable prefabricated substation requires comprehensive consideration of key factors such as application scenario, load characteristics, environmental conditions, expansion needs, and safety protection level. Based on your industrial project background, the following are the core dimensions and decision-making suggestions for selection:

 

Define the Application Scenario and Power Supply Mode

Terminal Type vs. Ring Network Type: If the project is an independent plant area or single-power supply, a terminal type prefabricated substation can be selected; if dual-power supply switching and improved power supply reliability are required (such as continuous production factories), a ring network type should be prioritized, supporting two high-voltage incoming lines.

Typical Applications: Prefabricated substations are widely used in industrial plants, mines, oil and gas fields, wind/photovoltaic power stations, etc., and are especially suitable for urban grid upgrades and space-constrained areas.

 

Match the Protection Level According to Environmental Conditions

Outdoor Use: Ensure the enclosure has moisture-proof, dust-proof, corrosion-proof, and condensation-proof capabilities. In cold northern regions (such as Harbin), attention should be paid to the temperature control system to prevent equipment failure due to low temperatures.

Protection Rating Reference:
IP33: Protects against solid foreign objects larger than 2.5mm, rainproof, suitable for general industrial environments;
IP54 and above: Dustproof, splashproof, suitable for high humidity, coastal, or dusty environments.

Special Environments: High altitudes, areas with highly corrosive gases, or areas experiencing vibration require customized environmentally friendly transformer substations with enhanced heat dissipation and corrosion resistance.
