Product descriptions from the supplier
Product Overview
The Compact Secondary Substation (CSS) is a highly integrated outdoor power facility, enclosing medium-voltage (MV) switchgear, distribution transformers, low-voltage (LV) switchboards, and auxiliary equipment within a single protective enclosure. It supports power conversion from 10-35kV MV input to 0.4kV LV output. Featuring modular design with arc-test certified components, its enclosure meets IP54+ protection standards, allowing direct installation in public-access areas like communities and commercial parks.
Type-tested for insulation strength and short-circuit withstand capability, the CSS incorporates an arc protection system and intelligent monitoring modules for remote condition surveillance. It completes full-process power conversion from high-voltage intake to low-voltage distribution in a compact footprint, delivering safe and reliable end-point power solutions for urban distribution networks.
Feature
Highly Integrated：Combines MV switchgear, transformer, and LV panel in a single enclosure, reducing footprint by 40%-60%. Directly converts 10-35kV to 0.4kV in one compact unit.
Modular Expandability：Standardized design with MV/transformer/LV compartments. Capacity adjustable from 500-2000kVA. Easy upgrades via module replacement.
Robust Safety Protection:IP54+ enclosure, arc-tested components, 42kV 1-minute AC withstand voltage, 31.5kA short-circuit tolerance.
Smart Monitoring:Real-time oil temperature/load monitoring. RS485/Ethernet interfaces for remote fault alerting.
Safe & Eco-Friendly:Noise reduction ≤55dB, landscape-friendly enclosure, anti-shock design compliant with IEC 62271-200.
Energy-Efficient & Reliable:Low-loss silicon steel core reduces no-load losses by 30%. MTBF exceeds 100,000 hours.
Rapid Installation：Prefabricated for 50% shorter on-site setup. Flexible deployment on slopes, narrow spaces.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
