The 10kV State Grid Replacement Prefabricated Substation (Metallic Type) is a high-performance power distribution solution purpose-built for the large-scale retrofitting of aging American-style box transformers across the State Grid infrastructure. Built upon the proven European-style box transformer platform, this metallic enclosure variant features enhanced structural strength and superior sealing performance. It incorporates optimized low-voltage configurations and precisely calibrated compensation systems to ensure seamless direct replacement of existing American box transformers, while integrating advanced intelligent monitoring capabilities for modern power grid management. The all-steel construction provides exceptional mechanical protection and durability for demanding industrial and outdoor applications.
Constructed with high-quality steel and treated with a special shot peening process followed by advanced anti-corrosion coatings, this metallic prefabricated substation offers outstanding mechanical strength and resistance to impact, wind, and sand erosion. The robust enclosure provides superior protection for internal components, ensuring reliable operation even in extreme weather conditions and harsh industrial environments.
This intelligent prefabricated substation features comprehensive remote monitoring capabilities. The transformer tank can be equipped with pressure gauges and thermometers with communication interfaces, while load switches can be fitted with travel switches. This enables real-time remote monitoring, operation, and maintenance, significantly reducing on-site inspection requirements and improving system reliability.
The fully sealed design ensures complete isolation of internal components from the external environment. The high and low voltage chambers achieve an IP54 protection rating, while the transformer body itself reaches an impressive IP68 rating. This exceptional sealing performance prevents oil oxidation and moisture ingress, greatly extending equipment service life and reducing maintenance needs.

Our American box transformer retrofit solutions are manufactured in strict compliance with international standards including JB/T10217, GB311.1, GB11022, and GB/T16927. Every unit undergoes comprehensive factory testing, including insulation tests, load tests, and protection function verifications, to guarantee exceptional quality and reliability. We offer a 2-year comprehensive warranty and lifetime technical support. Our dedicated after-sales team provides 24/7 emergency support, regular preventive maintenance, and equipment upgrade services to ensure your power distribution system operates continuously and efficiently.
Metallic substations offer superior mechanical strength and higher protection ratings, making them ideal for harsh industrial environments. Non-metallic substations provide better thermal insulation and corrosion resistance, suitable for coastal and polluted areas.
Yes, our monitoring systems support standard communication protocols and can be seamlessly integrated with most existing SCADA and power management systems.
Standard units typically ship within 15-20 working days, while custom configurations may require 25-30 working days depending on complexity.
