The 40.5kV~10kV modular prefabricated substation integrates electrical units such as transformers, multi-circuit high-voltage switchgear, reactive power compensation devices, insulated busbars, substation automation systems, communication, SCADA, metering, and DC power systems. All equipment is systematically, safely, reliably, and maintainably installed within a thermally insulated, fireproof, theft-proof, moisture-proof, rodent-proof, ventilated, fully enclosed, and movable steel enclosure.
This solution is ideal for urban and rural medium and small substations in the 40.5kV~35kV range, especially suitable for substation construction or retrofitting in industrial and mining enterprises. Its proximity to load centers reduces power supply radius and improves power quality, making it particularly effective for urban distribution network upgrades. Recognized as the “target model for 21st-century substation construction,” it meets State Grid Corporation standards, new rural electrification guidelines, and implementation frameworks—achieving a transformation from building a substation to buying an integrated one.
Land-saving Design:
The standard layout occupies only 230m², saving 60%–80% of land compared to traditional substations. It supports national land conservation policies.
Cost Efficiency & Reliability:
Most electrical components are self-manufactured, reducing costs. All equipment is installed indoors, insulated from environmental impacts. The metal-clad enclosure is corrosion-resistant, low-maintenance, long-lasting, and energy-efficient.
Modular Construction, Shortened Cycle:
Pre-engineered design templates reduce customization needs. Key modules—such as incoming, outgoing, transformer, and protection—can be rapidly deployed. The construction cycle is reduced to 3 months, compared to 1 year for traditional substations.
Eco-Friendly & Durable:
Minimal on-site construction; most work is completed indoors. Noise and electromagnetic radiation are confined within the metal enclosure. The all-metal structure outlasts brick-and-mortar or concrete alternatives, and components are recyclable.
