Prefabricated modular substations are highly integrated intelligent power equipment that integrates core components such as high-voltage switchgear, transformers, and protection devices into standardized cabins, enabling factory prefabrication, modular assembly, and rapid deployment. Their design aligns with the trend of smart grid development and is suitable for scenarios such as new energy infrastructure, urban power distribution, and industrial parks, significantly shortening construction cycles and reducing construction costs.

90% factory prefabrication rate , only basic construction and equipment hoisting are required on site, shortening the construction period by more than 60% (traditional solutions take 6 months, prefabricated modules only take 60 days).

The standardized cabin supports " plug and play " and is adaptable to complex terrain and space constraints.

Highly integrated: It integrates high-voltage switchgear, dry-type transformer, low-voltage distribution cabinet, intelligent monitoring system, etc., with flexible cabin size (commonly 6m×2.8m×3.2m ) and capacity covering 1MW~6MW .

Built-in intelligent protection devices (such as anti-islanding and overvoltage protection), response speed < 20ms , and support for remote monitoring and scheduling.

Reliable and durable: The cabin is made of fireproof and corrosion-resistant materials (such as rock wool insulation + galvanized steel plate), with a protection level of IP54 , adaptable to environments from -40 ℃ to +70 ℃ , and a service life of > 20 years.

The double-layer earthquake-resistant structure design can withstand an 8- magnitude earthquake, a level 12 strong wind, and 30cm of snow accumulation.

Green and energy-saving: Using non-metallic cabin materials (such as basalt fiber), production energy consumption is reduced by 50% , with no rust and no maintenance required.

The system's overall efficiency is ≥98.5% , and its no-load loss is reduced by 20% compared to traditional prefabricated substations.
