Technical Overview
Turnkey Pre-Engineered MV/LV Distribution Substations
Prefabricated compact substations (also known as packaged substations, kiosk substations, or pad-mount substations) integrate high-voltage incoming switchgear (RMU), a power transformer, and low-voltage outgoing switchboards inside a single weather-proof, tamper-resistant enclosure.
XinHuan's manufacturing plant produces both European Kiosk Substations (independent MV room, transformer room, and LV room layout with walk-in or non-walk-in designs) and American Pad-Mounted Substations (compact co-tank design with dead-front elbow connectors, ideal for underground residential and commercial distribution).
Every substation is completely assembled, pre-wired, and routine-tested at our Hefei factory before containerization, reducing site installation and commissioning time from weeks to just a few hours.

Technical Q&A
Frequently Asked Questions — Compact Prefabricated Substation Factory China (Kiosk & Pad-Mount)
European Kiosk substations feature three independent physical compartments (MV switchgear room, transformer room, LV distribution room) with full walk-in or aisle access, making them ideal for urban distribution with multiple outgoing feeders and automated metering. American Pad-Mounted units use a compact co-tank design where dead-front HV loop bushings and LV stabs share a common tamper-resistant cabinet, ideal for North and Latin American underground radial/loop distribution.
XinHuan kiosk substations are engineered and type-tested to IEC 62271-202 IAC-AB 20kA 1s. Pressure-relief flaps on the roof safely vent explosive gases upwards away from maintenance personnel and pedestrians in the unlikely event of an internal arc fault.
We integrate 12kV / 24kV / 36kV SF6 Gas Insulated Ring Main Units (YRM6 series), environmentally friendly Solid Insulated RMUs, or Vacuum Load Break Switches (LBS) with fuse combinations, configured as Ring Feed (CCF) or Radial Feed (CF).
The LV compartment incorporates a draw-out or fixed air circuit breaker (ACB/MCCB) with electronic trip unit, multi-channel outgoing MCCBs, digital multifunction power meters with RS485 Modbus, and automatic power factor correction capacitor banks with detuned reactors.
We manufacture enclosures from heavy-gauge hot-dip galvanized steel, marine-grade 304 or 316 stainless steel, aluminum-zinc alloy plate, or architectural GRC composite cement boards (blending seamlessly into residential landscapes) with C4/C5-M corrosion protection.
All MV connections, transformer cabling, LV busbars, secondary control wiring, interior lighting, and ventilation systems are 100% installed, wired, and dielectric-tested in our Hefei factory before shipment. On-site commissioning requires only positioning onto a concrete foundation slab and landing incoming/outgoing cables (typically 4 to 8 hours).
Substations up to 1000 kVA are designed within standard ISO shipping dimensions to fit directly into 20-foot or 40-foot High-Cube ocean containers. Larger 1600kVA–2500kVA kiosks ship via 40-foot Open-Top containers or Flat Racks with waterproof heavy-gauge shrink-wrap and corner crane lifting eyes.
Within 24 hours of receiving project parameters, our engineering team supplies a complete bid submittal package: single-line electrical schematic (SLD), general arrangement dimension layout (2D DWG & 3D STEP), concrete foundation plan, total weight calculation, and factory routine test schedule.
