Description

HV Compact Prefabricated Substation Product Description：

The YBW HV Compact Prefabricated Substation(European-style box transformer) is a compact all-in-one distribution unit integrating high-voltage, transformer, and low-voltage components. Engineered for power reception and distribution, it boasts a small footprint (1/10–1/5 the size of traditional civil substations of the same capacity), safe reliable operation, easy maintenance, and mobility—cutting design/construction costs significantly. Ideal for ring network, dual-power, or radial terminal systems, it is a modern solution for urban and rural substation upgrades.
Composed of three integrated functional compartments (high-voltage, transformer, low-voltage), the YBW HV Compact Prefabricated Substation offers flexible configurations. The high-voltage side supports multiple power supply modes and optional high-voltage metering. The transformer compartment accepts S11/S13 oil-immersed or SCB10/SCB11 dry-type transformers, paired with self-activating forced cooling and lighting. The customizable low-voltage compartment delivers power distribution, reactive compensation, metering, and more, optimizing power quality and management.
With anti-misoperation interlocking in the high-voltage compartment, optional transformer rails for easy access, and automatic lighting in all compartments, the unit ensures safe operation and hassle-free maintenance. Natural and temperature-controlled forced ventilation enables full-load transformer performance.
Its corrosion-resistant steel/aluminum alloy enclosure prevents rain and contaminants from entering, ensuring long-term outdoor use with excellent waterproof, dustproof, and anti-corrosion properties, plus a long service life and sleek finish.
HV Compact Prefabricated Substation Product Features：
  • Broad Voltage Compatibility：Supports 6.3kV/10.5kV/13.2kV high-voltage input, perfectly matching medium-voltage distribution network requirements for urban grids, industrial parks, and rural power system upgrades.
  • Compact & Space-Saving Design：Integrated all-in-one structure with a small footprint, occupying only 1/5–1/10 the area of traditional substations, and reducing on-site construction and land occupation costs significantly.
  • Factory Prefabricated & Fast Deployment：Fully assembled and tested in the factory; on-site installation only requires simple wiring connection, shortening the construction period and realizing rapid power supply.
  • Comprehensive Safety Protection：Equipped with overvoltage, overcurrent, short-circuit and lightning protection modules, and built-in anti-misoperation interlocking functions, ensuring safe and stable operation in complex distribution scenarios.
  • Customizable Configuration：Flexible options for transformer types (oil-immersed/dry-type), capacity (30kVA–2500kVA) and low-voltage output, meeting the personalized power distribution needs of different projects.
  • Rugged & Durable Structure：Adopts corrosion-resistant enclosure with IP54 protection grade, adapting to harsh outdoor environments such as rain, dust and extreme temperatures (-30℃~+50℃) for long-term reliable use.
