Intro
Against the backdrop of global energy transition, photovoltaic plants, EV charging hubs and modern factories need safer, faster-install power distribution solutions. YB series dry-type prefabricated substations have quickly become the mainstream replacement for old oil-filled box transformers.
1. Superior Fire & Environmental Safety
The core is epoxy resin cast dry transformer, with zero flammable insulating oil. It is flame retardant, explosion-proof, no oil leakage or soil pollution, perfectly fitting high-density sites like charging stations and factory workshops. Minimal maintenance is required compared to oil transformers.
2. Reliable Three-Compartment European Structure
It adopts an independent three-room layout: high voltage chamber, transformer chamber, low voltage distribution chamber.
Equipped with mechanical five-prevention interlocks, automatic temperature control cooling system, and IP33 anti-corrosion outdoor cabinet. Stable operation under rain, high heat and salt fog coastal environments.
3. Save Massive On-Site Time & Cost
Fully assembled, wired and load tested in our factory before shipment.
Only a flat concrete base is needed on-site; just lift the unit and connect cables to put it into use within one day. Its floor area is only 1/4 of a traditional brick power room, cutting civil engineering and labor costs sharply.
4. Flexible Customization & Wide Application
• Capacity: 100kVA–2500kVA, standard 10kV/0.4kV
• Custom options: Io T remote monitoring, PV anti-islanding protection, multi-function metering
• Global certifications: CE, CB, EAC, SASO for smooth export clearance
Perfect for solar power stations, centralized EV chargers, industrial parks, residential compounds and municipal engineering.
Safety, efficiency and eco-friendliness make YB dry prefabricated substations the top power choice for global new energy and construction projects.
