Function
High voltage power receiving and distribution
Receiving and distributing high voltage electrical energy through high voltage switchgear.
Low voltage distribution
Distribute low-voltage electrical energy to users through low-voltage distribution devices.
Transformer voltage reduction
Using distribution transformers to reduce high voltage electrical energy to low voltage electrical energy.
Protection and Control
Equipped with comprehensive relay protection devices and automatic control systems to ensure the safe and stable operation of the power grid.

Box-Type/Container-Type Substations
These are self-contained units assembled in a sealed, weatherproof steel structure that houses the high-voltage switchgear, distribution transformer, and low-voltage distribution equipment.
E-Houses
Similar to box-type substations, E-Houses are prefabricated buildings designed for easy transport and installation. They can also be offered as a "skid" for smaller, more compact applications or as a "mobile E- House" installed on trailers.
Trailer-Mounted/Vehicle-Mounted Substations
These are fully integrated substations mounted directly onto trailers or vehicles for the highest level of mobility and rapid deployment.
Compact Substations
Often integrated into the box-type design, compact substations are small, efficient, and highly integrated units that minimize their footprint.
Applications
Urban power supply renovation
In the process of urban power supply infrastructure renovation, box type substations have become the preferred solution due to their small footprint and short construction period.
New energy power plants
With the rapid development of new energy such as wind power and photovoltaics, box type substations are also widely used in new energy power plants as collection and transformation transmission points for electrical energy.
Industrial and mining enterprises
In factories, mines, and other industrial and mining enterprises, box type substations provide stable and reliable power supply for production lines.
Construction site
In situations where temporary power supply is required, such as construction sites, box type substations provide a convenient mobile power distribution solution.
