Product Description

BOX-TYPE SUBSTATION

A box - type substation is a compact power distribution device that integrates high-voltage switchgear, distribution transformers, low-voltage devices, and intelligent systems.

It contains a high - voltage chamber (such as load switches), a transformer chamber (oil - immersed or dry-type), and a low-voltage chamber (such as power distribution cabinets), and realizes power conversion, distribution, and protection through modular design.

It has a compact structure, occupying only 1/10 - 1/5 of the land area of a traditional substation.

The enclosure protection level reaches above IP33D, and it can adapt to an environment with a temperature range from - 40°C to + 40°C.

It supports intelligent monitoring, can remotely monitor the status, give early warnings of faults, and can also be connected to new energy sources.

It is widely used in urban power distribution networks (commercial centers, residential communities), new energy projects (photovoltaic, wind power), and temporary power - use scenarios, and is a key device in modern power systems.

Functional Advantages

ALL-IN-ONE INTEGRATED DESIGN

Integrates MV switchgear, transformer, and LV panel in one enclosure to simplify engineering interfaces and deliver true one-stop power distribution.

COMPACT FOOTPRINT, FASTER PROJECT DELIVERY

The modular structure dramatically reduces land use versus traditional substations, supporting rapid deployment for space-limited urban and industrial sites.

TRANSFORMER OPTIONS FOR DIFFERENT SAFETY & COST TARGETS

Available with oil-immersed or dry-type distribution transformers, allowing selection based on fire safety expectations, budget, and operating environment.

OUTDOOR-READY ENCLOSURE & ENVIRONMENTAL ADAPTABILITY

Built with steel housing and designed for outdoor installation; engineered to operate in harsh climates (e.g., -40°C to +40°C) with enclosure protection options to suit site conditions.

Core Applications

URBAN DISTRIBUTION NETWORKS

Widely used in commercial centers, residential communities, and business parks to deliver reliable MV/LV distribution with minimal footprint and fast commissioning.

RENEWABLE ENERGY PROJECTS (SOLAR & WIND)

Commonly applied in solar compact substations and wind power distribution/collector systems, enabling scalable installation and easier operation & maintenance across sites.

INDUSTRIAL PLANTS & LOGISTICS FACILITIES

Supports factories, warehouses, and industrial parks that need robust package substation solutions for independent power nodes and stable production electricity.

INFRASTRUCTURE & PUBLIC UTILITIES

Suitable for airports, rail/metro stations, tunnels, road lighting distribution points, and municipal power upgrades where outdoor installation and reliability are critical.

TEMPORARY POWER & EMERGENCY DEPLOYMENT

Ideal for construction sites, temporary events, and emergency restoration projects requiring rapid installation and reliable short-to-medium term power distribution.
