Built to IEEE C37.121, ANSI C57.12.34 and IEC 62271-202. Entogo designs and builds the 36 kV Outdoor Compact Unit Substation in its own factory with a vertically integrated supply chain: this product ships in 16–24 weeks (new UL or CSA certification can extend that, within a guaranteed 36-week worst case), and every Entogo product carries a minimum 36-month manufacturer warranty. The **36 kV outdoor compact unit substation** is the North American–conventional form factor for distributed medium-voltage service: a single factory-built, weather-tight assembly that combines incoming 34.5 kV switchgear, a liquid-filled distribution transformer (**1,000 – 10,000 kVA**) and a low-voltage section, all delivered on a skid or pad ready for set-down on a prepared foundation. It replaces the older approach of bolting a pad-mounted transformer to a separate medium-voltage switchgear and low-voltage cabinet on site. Engineered to **IEEE C37.121** (unit substations), **ANSI C57.12.34** (three-phase pad-mounted-equipment enclosure integrity) and IEC 62271-202 (high-voltage / low-voltage prefabricated substation), it is configured as a step-up unit for solar PV, wind, and battery-storage collector duty, or as a step-down service entrance for industrial and commercial loads. Dead-front loadbreak elbows give crews the same operator-safe switching they expect from pad-mounted apparatus; microprocessor protection, SCADA, and an **FR3** natural-ester insulation option are available on request. Cold-climate, wind / seismic and corrosive-environment packages are specified per site. ## Key features - Single weather-tight, walk-in enclosure containing HV switchgear, transformer and LV section — replaces a bolted-together pad-mount + cabinet assembly. - Designed to IEEE C37.121 (unit substations) and IEC 62271-202 — directly comparable with North American and European OEMs. - Dead-front loadbreak elbows on the medium-voltage side for operator-safe switching; live-front porcelain bushings available where required. - Configurable as step-up (renewables collector) or step-down (industrial / commercial service). - Mineral-oil filled standard; FR3 natural ester available for less-flammable, biodegradable insulation. - NEMA 3R / IP54 enclosure with hot-dip galvanized base frame, marine-grade powder coat, anti-condensation heaters. - Microprocessor protection relay (SEL / ABB / Schneider class), SCADA-ready, optional remote disconnection and metering. - Factory-tested as a complete substation to reduce on-site commissioning to days, not weeks.
