Description
Prefabricated Substation (Box-Type / Compact Substation)
This prefabricated substation — also called a box-type or compact substation — integrates a 12 kV high-voltage unit, a 30-2000 kVA transformer and a 400 V low-voltage unit into a single corrosion-protected, IP23-rated enclosure. It is designed for urban and rural distribution networks, industrial parks, residential communities and renewable-energy collection stations.

Key Features
  • Robust Corrosion-Proof Frame — made of antiseptic groove steel and angle steel for high mechanical strength and rigidity
  • Flexible Enclosure Materials — available in cold-rolled steel plate, stainless steel plate, aluminum alloy plate or composite color plate
  • Modular Compartment Layout — separate chambers that can be arranged in various layouts to fit the site
  • Convenient Maintenance — all rooms equipped with lighting for easy monitoring and servicing
  • Thermal Control — double-layer roof reduces thermal radiation; transformer cooled by natural ventilation with automatic top axial-flow fan
  • Damp-Proof Sealing — all rotating connection parts fitted with sealing devices for good moisture resistance
  • Five-Prevention Safety Interlock — complete anti-misoperation functions on HV side to ensure maintenance safety
  • Compact & Clean Design — neat appearance that blends into the surrounding environment
Applications
  • Urban & Rural Distribution Networks — incoming and outgoing feeders for medium-voltage distribution
  • Industrial Parks & Factories — reliable power supply for production facilities
  • Residential & Commercial Communities — compact substations for housing estates and commercial areas
  • Renewable Energy — collection and step-up for wind and solar power stations
  • Temporary & Construction Power — rapid-deployment supply for construction sites and mining operations
Frequently Asked Questions (FAQ)
What is a prefabricated (box-type) substation?
It is a compact substation that combines the high-voltage switchgear, transformer and low-voltage distribution equipment into one factory-built, pre-wired enclosure, delivered ready for on-site installation.
What voltage and capacity ratings are available?
The HV unit is rated 12 kV, the LV unit 400 V, and the transformer capacity ranges from 30 to 2000 kVA.
What does IP23 mean?
IP23 means the enclosure protects against solid objects larger than 12.5 mm and against water spray, making it suitable for typical outdoor installations.
What is the "five-prevention" function?
It is a set of five anti-misoperation interlocks on the high-voltage side (e.g. preventing opening/closing under load, closing while earthed, entering a live compartment) that protect operators during maintenance.
What is the noise level?
The substation operates at a sound level of 55 dB or below.
