- Product Introduction
Products Description
Our Electric's YBW-35kV is a fully prefabricated, integrated power distribution solution that seamlessly combines high-voltage switchgear, distribution transformers, and low-voltage switchgear into a single robust unit. Encased in a highly durable, dust-tight, moisture-proof, and corrosion-resistant metal enclosure, this European-style box substation is engineered for ultimate reliability in harsh outdoor environments.
Modular Internal Configuration
The YBW-35kV substation features a highly flexible, modular design divided into three independent compartments to ensure maximum safety and operational efficiency:
High-Voltage Unit
- Location: Installed at one end of the enclosure.
- Configuration: Equipped with SF₆ gas-insulated Ring Main Units (RMU) or vacuum circuit breaker cabinets, complete with busbars, cables, and advanced protection/control devices.
- Key Features: Compact footprint, maintenance-free operation, and superior operational safety.
Transformer Unit
- Location: Centrally located for optimal thermal management and isolation.
- Configuration: Includes the distribution transformer, cooling system, and comprehensive earthing & safety devices.
- Optional Transformer Types:
- Dry-Type Transformer: The most widely adopted solution, utilizing air cooling and offering outstanding fire resistance.
- SF₆ Gas-Insulated Transformer: Fully sealed construction for enhanced environmental friendliness and safety, ideal for harsh and extreme environments.
- Amorphous Alloy Transformer: Features ultra-low no-load loss, providing a high-efficiency, energy-saving solution.
Low-Voltage Unit
- Location: Installed at the opposite end of the enclosure.
- Configuration: A fully integrated LV power distribution system.
- Included Equipment: Incoming/outgoing feeder panels, MCCBs, MCBs, contactors, reactive power compensation capacitor banks, energy meters, CTs, and auxiliary power supply units.

FAQ
Q1: Can the internal configuration (HV/LV switchgear and transformers) be customized?
A: Absolutely. As a manufacturer, we offer fully customized solutions. You can choose different types of transformers (dry-type, oil-immersed, or amorphous alloy), RMU brands, and LV panel layouts based on your specific project requirements and local grid standards.
Q2: What is the typical lead time for production and delivery?
A: Since each substation is custom-assembled, the standard production lead time is typically 30 to 45 days after the technical drawings are confirmed. We can expedite production for urgent project schedules upon request.
Q3: How do you ensure the substation can withstand harsh outdoor environments?
A: Our YBW-35kV enclosures are treated with advanced anti-corrosion coatings and are designed to IP54D protection standards. They are fully sealed against dust, moisture, and extreme temperatures, ensuring reliable operation in tough conditions.
Q4: Do you provide installation guidance and after-sales support?
A: Yes. We provide comprehensive installation manuals, wiring diagrams, and video tutorials. If needed, our engineers can also provide remote technical support via video call to guide your local installation team.
