11KV 33KV Outdoor Box Type Substation Intelligent Pre Installed Transformer

The YB Series Pre-installed Box-Type Substation (also known as a European-style substation) is a compact, factory-assembled power distribution solution. It integrates high-voltage switchgear, a distribution transformer, and a low-voltage distribution system into a single, weather-resistant, and aesthetically pleasing enclosure.

Designed for 11kV, 22kV, and 33kV networks, the YB series is the definitive "plug-and-play" solution for urban grids, residential complexes, and large-scale industrial sites. By consolidating three major components into one unit, it significantly reduces the land area required for power infrastructure and slashes on-site installation time by up to 80% compared to traditional civil substations.

• Integrated Turnkey Design: Factory-wired and pre-tested. On-site requirements are limited to foundation preparation and cable termination, ensuring rapid project commissioning.

• Intelligent Monitoring System: Features advanced digital relays and communication modules (RS485/Modbus) for real-time tracking of transformer temperature, load data, and fault alarms via SCADA.

• Environmental Resilience: The enclosure is available in stainless steel, aluminum alloy, or GRC (Glass-fiber Reinforced Concrete), offering superior protection against UV, corrosion, and extreme temperatures (-40°C to +45°C).

• Compact Footprint: Ideal for space-constrained urban environments, public parks, and narrow industrial corridors where a full-scale substation building is not feasible.

• Multi-Compartment Safety: Features distinct, fire-walled compartments for High-Voltage (HV), Transformer, and Low-Voltage (LV) equipment, preventing fault propagation and ensuring operator safety.

1. Urban Power Grids: Reliable secondary distribution for high-density residential areas and metropolitan commercial hubs.

2. Renewable Energy Sites: Serving as the central collection substation for solar PV farms and onshore wind projects.

3. Industrial Parks: Dedicated power supply for factories, mining facilities, and manufacturing clusters.

4. Temporary Infrastructure: Ideal for large-scale construction sites or oil/gas drilling rigs where mobile power is required.

• Total Customization: We offer a wide range of enclosure finishes (including wood-grain or stone-texture) to help the substation blend into park landscapes or architectural environments.

• Optimal Thermal Management: Equipped with intelligent temperature-controlled forced-air cooling and high-performance thermal insulation to prevent internal condensation and overheating.

• Superior Safety Interlocks: Every unit features a comprehensive "Five-Prevention" mechanical interlocking system to eliminate operator errors during maintenance.

• Global Component Support: We can integrate preferred switchgear and breaker brands, including ABB, Schneider, or Siemens, ensuring global compatibility and spare parts availability.

Q: Can this substation be used in coastal areas?

A: Yes. For coastal or highly corrosive environments, we provide SS316 stainless steel enclosures with specialized C5-M marine-grade anti-corrosion coatings.

Q: What is the lead time for a 1250kVA unit?

A: Standard configurations typically ship within 6 to 8 weeks following drawing approval.

Q: Does it support remote switching?

A: Absolutely. By integrating motorized actuators and smart RTUs, the substation can be operated remotely via your centralized control room (SCADA).
