Compact Secondary Substation

A compact secondary substation is the critical bridge between the medium‑voltage grid and the low‑voltage power that actually runs your equipment. Our CSS units are type‑tested and arc‑tested assemblies containing MV switchgear, distribution transformers, LV switchboards, connections, and auxiliary systems – all factory‑built and operationally tested before shipment.

We have been manufacturing compact secondary substations for nearly a decade, and we have learned that reliability is not a feature – it is a necessity. That is why every compact secondary substation we produce is made from heavy‑gauge steel with advanced corrosion protection, and includes intelligent monitoring for voltage, current, and transformer temperature. Our 2000‑m² facility and 40‑person team ensure that each unit receives individual attention.

What sets our compact secondary substation apart is the speed of deployment. Because it is pre‑wired and pre‑tested, on‑site installation takes hours instead of weeks. We have delivered compact secondary substations to commercial centers, industrial parks, and even remote renewable sites. Our customers appreciate the plug‑and‑play simplicity, and we back that with a 1‑year warranty and full after‑sales support.

• Small industrial facilities
• Renewable power plants
• Hotels, shopping centres, office buildings
• Residential communities
• Temporary power supply for events and construction

We can build your compact secondary substation according to your own technical drawings or prototypes. While we do not offer OEM branding, we can tailor the capacity, voltage, and internal layout to your exact needs. Custom sample development takes about 1 week, and our MOQ is only 1 unit – so you can test before you scale.

Every compact secondary substation undergoes 100% inspection before packing, including voltage withstand, insulation resistance, mechanical operation, and relay calibration. We accept third‑party inspections at any stage. We source our components and control every production step – no outsourcing, no shortcuts.

Our 1‑year warranty covers all manufacturing defects. We have dedicated staff for after‑sales service, not an outsourced call centre. We monitor your power usage regularly and resolve issues promptly to ensure safety and continuity. If you need help, we are just a call away.
