1. Product Definition & Core Composition

A box-type substation (also known as a “pre-installed substation” or commonly referred to as a “European-style box substation”) is a compact complete power distribution device. Its core feature is the organic integration of multiple power equipment into one or more enclosed cabinets, mainly including:

High-voltage switchgear
Power distribution transformer
Low-voltage switchgear
Electric energy metering equipment
Reactive power compensation device

2. Core Features

Factory Pre-installation & Integration: All components are assembled, wired and fully tested in the factory to ensure equipment compatibility and operational reliability;
Overall Transportation & Deployment: The complete set of equipment is transported to the usage site as a whole unit in cabinets, without the need for on-site disassembly and assembly;
Rapid Commissioning Capability: On-site, only simple external wiring and commissioning work are required to quickly put it into operation, significantly shortening the construction cycle.

3. Core Advantages

As a high-quality alternative to traditional civil engineering substations, the box-type substation highlights modern power distribution advantages:

Standardized Design: Complies with unified technical specifications, featuring strong component versatility and controllable quality;
Miniaturized Layout: The integrated design greatly reduces the floor space, suitable for scenarios with limited space;
Maintenance-Free Performance: Optimized commissioning is completed during factory pre-installation, no frequent maintenance is required during operation, reducing operation and maintenance costs;
Mobility: The cabinet structure facilitates overall migration, flexibly adapting to load changes or site adjustment needs.

4. Application Positioning

It represents the modern development trend of standardization, miniaturization, maintenance-free and mobility in the power distribution field. It is suitable for scenarios with high requirements for flexibility, convenience and space utilization of power distribution devices, and is an efficient alternative to traditional civil engineering substations.
