European YB-12 • American ZGS11 • Solar YZC • BESS Container
Prefabricated Compact Substations & Solar Inverter Cabins
Factory-assembled, plug-and-play medium-to-low voltage transformation packages. Incorporating high-voltage switchgear, energy-efficient transformers, low-voltage distribution panels, and smart SCADA automation inside thermal-insulated weather-proof enclosures.
YZC Utility-Scale Solar PV Step-Up Integrated Substation (35kV / Up to 6250kVA)
// Modular Turnkey Package
Engineered for Rapid Field Commissioning & Harsh Environments
Traditional civil substation construction requires 6 to 12 months of high-cost on-site civil works. AIKey prefabricated substations arrive on-site 100% factory pre-wired, tested, and pre-commissioned, reducing on-site installation time to less than 48 hours.
- ✓ Thermal-Insulated Double-Skin Enclosure: Aluminum-zinc coated steel or Glassfiber Reinforced Cement (GRC) with flame-retardant polyurethane core prevents interior solar heat buildup.
- ✓ IP54 Weatherproof & Sand-Dust Protection: High-efficiency labyrinth air vents with automatic dust filtration and thermostatic exhaust fans maintain optimal operating temperatures.
- ✓ Solar & BESS Tailored Architecture: YZC dual-split transformer windings match 1500V central solar inverters, preventing circulating harmonic currents between inverter blocks.
- ✓ Intelligent SCADA & Telemetry: Standard optical fiber ethernet switch, IEC 61850 / Modbus RTU communication, remote fault diagnostics, and microcomputer arc-flash protection.
