On city streets, in industrial parks, and even along remote village roads, you might spot some square-looking "big boxes." Positioned in inconspicuous spots along the road, these are indispensable "all-rounders" in modern power systems—the box-type substation.
A box-type substation (abbreviated as "box substation") is a compact power station that integrates high-voltage switchgear, transformers, and low-voltage distribution devices into a single unit. Think of it as a "power integration package" that packs all the functions of a traditional substation into a relocatable metal enclosure. Box-type substations are better suited for scenarios requiring rapid deployment and flexible power supply, while traditional substations are ideal for long-term, stable, high-load demands.
Appearance:
The enclosure can be made from steel plates, aluminum alloy, composite panels, stainless steel, or glass fiber reinforced cement (GRC). Shanxi Beike Electric primarily manufactures enclosures using steel plates and composite panels.
Internal Structure:
Includes a high-voltage compartment, transformer compartment, and low-voltage compartment, ensuring the safe conversion of electrical power from high to low voltage.
Comparison Item | Box-Type Substation | Traditional Substation |
Construction Period | 1-2 weeks to commissioning | Months or even years |
Footprint | Minimal (can be placed in green belts) | Requires dedicated land |
Flexibility | Mobile and reusable | Fixed installation, difficult to relocate |
Cost | Lower (saves civil engineering costs) | Higher (requires building construction) |
Applicable Scenarios | Cities, construction sites, temporary power | Major grid hubs |
