Price Range Of Prefabricated Substations

The price range of prefabricated substations is influenced by various factors, typically fluctuating between tens of thousands to hundreds of thousands of yuan or even higher, depending on the configuration and project requirements.

 

Based on the equipment composition and application scenario, the price is mainly determined by the following core components:

Transformer Type and Capacity: The transformer is the core of the cost. For example:

Small prefabricated substations (e.g., 100kVA~630kVA): Prices are mostly between 50,000 and 200,000 yuan.

Medium and large-scale projects (e.g., 1000kVA and above): Prices can reach 200,000 to 500,000 yuan or higher.

Dry-type transformers are more expensive than oil-immersed transformers, and S13 series energy-saving transformers are also more expensive than S11 series.

 

Equipment Configuration and Brand:

The brand and insulation method (e.g., gas insulation or air insulation) of components such as high-voltage switchgear, low-voltage switchgear, metering devices, and circuit breakers significantly affect the price. Using imported or first-tier brand components (e.g., Schneider Electric, ABB) results in a higher overall cost.

 

Customization Level:

Prefabricated substations are custom-made products, requiring construction tailored to electrical drawings. Price differences arise from variations in project location, grid connection standards, and protection levels (e.g., IP54 dust and water resistance).

 

Special Application Scenarios:
Photovoltaic step-up transformers" in distributed photovoltaic projects generally range in price from 150,000 to 500,000 yuan, depending on the installed capacity and grid connection requirements.

Temporary power supply at construction sites or mobile transformer substations, due to simplified configurations, may be priced as low as 30,000 to 80,000 yuan.

Prefabricated modular substations also include the cost of the substation casing, which costs approximately 3,000 to 5,000 yuan per cubic meter, further increasing the overall cost.
