All In One Box Type Transformer Substation 11KV 33KV Outdoor Prefabricated IP54

The YB Series European-style prefabricated substation (also known as a Compact Substation or Unitized Substation) is an all-in-one power distribution solution designed for urban grids, residential complexes, and industrial parks. Unlike traditional open-air substations, the YB series integrates the High-Voltage Switchgear, Distribution Transformer, and Low-Voltage Distribution Panel into a single, factory-tested, weatherproof enclosure.

Its "European-style" layout prioritizes a compact footprint and aesthetic integration into the environment while maintaining strict isolation between high and low-voltage compartments to ensure operator safety.

• Compact & Aesthetics-Focused: Occupation area is significantly smaller than traditional civil-work substations. The exterior can be customized with various colors and textures (such as wood-grain or stone-style) to blend with urban landscapes.

• High-Grade Protection (IP Rated): The enclosure is built from aluminum alloy, stainless steel, or glass-fiber reinforced cement (GRC). It provides superior resistance against corrosion, UV rays, and extreme weather, with a protection rating of IP44 or IP54.

• Flexible Modular Layout: Features an "h" or "L" type layout. The HV room, Transformer room, and LV room are separated by independent metal partitions to prevent fault propagation.

• Low-Loss Transformer Integration: Typically equipped with energy-efficient oil-immersed transformers (S11/S13 series) or dry-type transformers (SCB series) depending on the fire safety requirements of the installation site.

• Intelligent Ventilation: Equipped with automatic temperature-controlled forced-air cooling systems, ensuring the transformer operates within safe temperature limits even during peak summer loads.

1. Urban Residential Areas: Providing safe, quiet, and reliable power distribution for high-density housing.

2. Infrastructure Projects: Powering airports, railway stations, and tunnels where space is at a premium.

3. Industrial Parks: Reliable energy supply for manufacturing facilities requiring localized voltage stepping.

4. Commercial Complexes: Integrating seamlessly into the parking or utility areas of shopping malls and office towers.

• Turnkey Solution: All components are pre-wired, pre-assembled, and pre-tested in our factory. This reduces on-site installation time by up to 80%.

• Safety First: Equipped with "five-proof" mechanical interlocks to prevent accidental contact with live parts and incorrect operations.

• Maintenance-Friendly: Designed with front and rear access doors, allowing technicians to perform routine inspections and maintenance easily.

• Custom Engineering: We support tailor-made internal configurations, including the integration of smart meters, remote monitoring units (RTU), and specific brands of breakers (ABB, Schneider, etc.).

Q: What is the difference between European-style (YB) and American-style (ZGS) substations?

A: The European-style (YB) is larger but more flexible, allowing for the replacement of the transformer or switchgear independently. The American-style (ZGS) is smaller as the transformer core and switchgear are often housed in the same oil tank.

Q: Can this substation be used in coastal areas with high salinity?

A: Yes. We offer specialized 304 or 316 Stainless Steel enclosures with C5-M anti-corrosion coating specifically for coastal and high-humidity environments.

Q: How do you ensure the cooling of the transformer in a closed box?

A: We use a combination of natural convection through louvered vents and automated exhaust fans that trigger when the internal temperature reaches a set threshold.

YB intelligent pre-installed substation

This series of intelligent box substation is by the high voltage unit, power transformer, low voltage unit, measurement unit and intelligent system, optimize the combined into a complete intelligent power supply complete sets of equipment, its function, wide use, more safe and reliable operation, nice appearance, and has convenient installation, covers an area of less, less maintenance, less investment, quick effect, long service life, etc. It can be used as transformer and distribution equipment for urban buildings, residential areas, municipal facilities, factories, mines, highways, wharves, oil fields and temporary electricity departments and places.
