Compact Substation Unit Trend Report

The box-type substation, or prefabricated substation, is light, easy to install and maintain, and has a neat appearance. It is well-suited for use in industrial areas, cities, parks, and residential neighborhoods. This type of substation contains high-voltage switchgear, busbars, an automation system, communication units, remote control, metering equipment, capacitor compensation, and DC power units, all packed into a weather-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, insulated, and fully enclosed steel box. The main features are as follows:

Advanced and Safe
The box uses high-quality materials and technology, with an outer shell of aluminum-zinc-coated steel, which is rust-resistant for up to 20 years. Inside, it has insulation for fire protection, air conditioning, and a dehumidifier, allowing it to work well in extreme temperatures (-40°C to +40°C). Main equipment like switchgear, dry transformers, and vacuum switches are fully enclosed, with no exposed parts, ensuring high safety. Automated systems allow for remote and unattended operation.

High Automation
The substation is fully automated, with systems that allow remote monitoring and control. Each part works independently, with protection systems to ensure safe operation. Remote monitoring of humidity, temperature, and smoke is possible, supporting unattended use. There is also an option for remote video monitoring.

Prefabricated in Factory
Only a basic design is needed before manufacturing. The substation is pre-assembled and tested at the factory, allowing quick installation. On-site setup is minimal, needing only placement, cable connections, and a few tests. It takes about 5 to 8 days from installation to full operation, which shortens project timelines.

Flexible Setup
Each box works as an independent system, so users can combine boxes in various ways to fit their needs.

Cost-Efficient
A box-type substation can cut costs by 40% to 50% compared to regular substations of simil
