Compact Substation

A Compact Substation (also known as a Package Substation or Prefabricated Substation) is a fully integrated power distribution solution that combines medium voltage switchgear, transformer, and low voltage distribution equipment into a single enclosed unit.
It is designed for efficient, safe, and space-saving power distribution, widely used in urban infrastructure, industrial facilities, renewable energy systems, and commercial developments.

• Small size, reasonable and compact structure;
• Fully sealed fuel tank, fully insulated design, safe and reliable operation;
• Strong overload capacity, excellent resistance to sudden short circuit;
• Both ring network and terminal power supply can be used.
• Easy operation and reliable power supply;
• Energy saving, low loss;
• Good impact resistance;
• Cable connector number can operate 200A load current, mechanical life and long electrical life

1. Medium Voltage (MV) Switchgear

Ring Main Unit (RMU) or metal-clad switchgear

Protection and control of incoming power

2. Transformer

Oil-immersed transformer or dry-type transformer

Voltage transformation (e.g., 11kV/0.4kV, 33kV/0.4kV)

3. Low Voltage (LV) Distribution Panel

Power distribution, metering, and protection

Equipped with circuit breakers, meters, and control devices
