Ryan Packaged Substations
Ryan factory-built packaged substations — European-style compact (prefabricated) substations and American-style pad-mounted transformer units up to 44 kV / 10 MVA — genuine equipment made available through our partnership network, with 24-hour response on production slot and lead time for customers worldwide.
Genuine Ryan packaged substations from SENTRADO
Ryan (Jiangsu Ryan Electric Co., Ltd.) builds complete factory-assembled distribution substations: the European-style compact/prefabricated substation integrating HV switchgear, distribution transformer and LV switchgear in one walk-in enclosure (per GB/T 17467, up to 35 kV), and the American-style pad-mounted transformer with dead-front construction for underground distribution networks (up to 44 kV, up to 10,000 kVA, built to GB, IEC, IEEE, UL, CE and ASTA standards). These units are genuine Ryan products made available through our partnership network, supplied with FOB, CIF or DDP terms, type-test certificates and full export documentation. We reply within 24 hours with a human response on production slot and lead time — contact us for live stock & lead time.
SENTRADO (Beijing Xinshentuo Technology Co., Ltd.) is an industrial automation and electrical-equipment export company with 25+ years of experience. Ryan transformers, switchgear and packaged substations are made available through our partnership network, with type-test and export documentation.

Technical specifications
Parameters below are taken from official Ryan product pages and product documentation for compact/prefabricated and pad-mounted substations.
| Product range | European-style compact (prefabricated/box-type) substation; American-style three-phase and single-phase pad-mounted transformers |
|---|---|
| Compact substation standard | GB/T 17467-2020 (high-voltage/low-voltage prefabricated substation) |
| Voltage class | Compact substations: up to 35 kV; pad-mounted units: up to 44 kV |
| Capacity range | Compact substations: main capacities up to 2,000 kVA (YB box-type) and up to 5,000 kVA in the prefabricated compact range; pad-mounted: up to 10,000 kVA (10 MVA) |
| Integrated equipment (European style) | HV switchgear cabinet, distribution transformer (oil-immersed or dry-type), LV distribution panel and enclosure shell, factory-assembled as one unit |
| Pad-mounted construction | Dead-front, tamper-resistant enclosure; HV load-break/sectionalizing switch and ring/feed options in one sealed tank; loop-feed and radial configurations |
| Primary voltages | Compact: 6 / 10 / 11 / 15 / 20 / 22 / 33 / 34.5 / 35 kV class; pad-mounted: 12.47, 13.2, 13.8, 19.9, 20, 22, 24.9, 33, 34.5 kV class |
| Secondary voltages | 220 / 380 / 400 V and 120 / 208 / 240 / 415 / 480 V class |
| Transformer options | Oil-immersed or cast-resin dry-type; copper or aluminum windings; mineral oil, FR3 or silicone fluid; cooling ONAN/ONAF/KNAN/KNAF |
| Enclosure options | Cold-rolled steel, aluzinc (galvalume), stainless steel or GRC concrete; corrosion-resistant multi-layer paint finish; chimney/ventilation arrangements |
| Configurations | Ring-main, dual-source, terminal and HV-metering arrangements; parking stands, feed-through bushings and five-point latching on pad-mounted units |
| Standards & tests | GB, IEC, IEEE, UL, CE, ASTA; routine tests per ANSI/IEEE/NEMA (polarity, resistance, losses, impedance, applied/induced voltage, impulse, ratio, leak test) |
Only parameters confirmed on official Ryan sources are listed. Substations are project-engineered to your single-line diagram; contact our engineers with voltage class, capacity, vector group and enclosure requirements for a configured quotation.
Project supply & engineering
Three ways our team supports your packaged-substation project: genuine factory-built supply, single-line engineering review and complete-substation BOM handling.
Genuine factory-built units
Ryan compact and pad-mounted substations are made available through our partnership network as genuine factory-built equipment with type-test certificates. Share your specification and our engineers verify capacity, voltage class and configuration before production release.
Single-line engineering review
Our engineers review your single-line diagram for ring-main vs terminal configuration, metering placement, vector group, cooling class, enclosure material and protection/IP rating, and coordinate factory drawings before production.
Complete substation BOM
We can quote the full scope — transformer, HV ring-main units, LV switchgear, enclosure, auxiliary power, protection and metering — together with Ryan cast-resin or oil-immersed transformers and switchgear lineups, in one project shipment.
Typical applications
Factory-assembled substations for fast site deployment — where civil substation construction must be minimized or underground distribution requires pad-mounted gear.
- Urban and industrial 10/35 kV distribution with compact substations
- Residential and commercial underground distribution (pad-mounted)
- Mining, oil & gas and remote industrial sites
- Data centers and utility backup feeders
- Rural electrification and ring-main distribution networks
- EPC projects requiring rapid, low-maintenance power supply
