Cabinet
Structure
Key components of the 1000 kVA compact substation provide waterproofing, dustproofing and corrosion resistance for harsh environments.
-Transformer Compartment: The core unit for voltage step-up/step-down conversion.
-Switchgear Compartment: Includes incoming switches, load break switches, disconnectors and combined switches.
-Cable Tunnel: Used for cable maintenance.
-Cabinet Compartment: Ensures proper air conditioning for the substation and serves as a passage for metering, dispatching and monitoring devices.
Auxiliary devices, such as distribution panels and cabinet-type racks, offer circuit protection, control, display and communication functions for the power distribution system.
Control devices include various control panels for operating and monitoring the substation’s functions.

Safety Protection Measures
Explosion & Fire Prevention
For environments with explosive gases or fire risks, necessary explosion-proof and fire-resistant measures should be implemented inside the substation, such as using flame-retardant materials.
Five Protection Interlocking Mechanism
1.Prevent accidental opening/closing of circuit breakers
2.Prevent load-breaking disconnect switch operations
3.Prevent live grounding wire installation
4.Prevent energizing with grounding wires connected
5.Prevent unauthorized access to live compartments
Dehumidification
In humid environments, dehumidification devices should be installed inside the enclosure to prevent condensation, thereby protecting electrical components from damage.
Ready-to-ship Finished Products
Operation
Daily Inspection
1.Check the substation’s exterior for damage
2.Ensure door locks are intact
3.Verify that ventilation openings are not blocked
Electrical Testing
Conduct preventive tests on the electrical equipment inside the substation at scheduled intervals to ensure they are in good condition.
Regular Maintenance
1.Properly maintain key components
2.Replace aged or damaged parts in time
Fault Handling
1.Respond promptly with corrective measures to restore power supply
2.Document fault details for further analysis and improvement
Frequently Asked Questions
What is inside a compact substation?
The package combines a medium-voltage switchgear or ring main unit, a distribution transformer, and a low-voltage panel in a single enclosure, factory-assembled and pre-tested.
What voltage classes and ratings are available?
Standard configurations run from 11 kV to 35 kV on the MV side with transformer ratings typically from 315 kVA to 2500 kVA. Ratings outside this range can be engineered on request.
Is the enclosure suitable for outdoor installation?
Yes. The enclosure is designed for outdoor use with IP-rated protection, corrosion-resistant coating and ventilation matched to the transformer rating.
How is the compact substation delivered and installed?
It is delivered as a factory-tested package ready for placement on a prepared foundation, which shortens site works compared with separately installed switchgear and transformer.
Can the protection and metering scheme be customized?
Yes. Protection relays, metering, remote signalling and SCADA interfaces are configured to your utility or project specification.
