YBM Series Prefabricated Box-Type Substation

(YBM Prefabricated European-Style Box Substation)

1. Product Introduction

The YBM series prefabricated box-type substation (European-style box substation) is a factory-assembled, complete power supply solution integrating high-voltage switchgear, distribution transformers and low-voltage power distribution devices. Adopting a compact structural design, it integrates comprehensive functions including power supply, transformation, control, protection and metering.

Designed for direct floor installation, it serves as an ideal replacement for traditional civil engineering substations. It features rapid installation, reliable operation and strong environmental adaptability, making it the optimal power supply solution for urban-rural power grid renovation, industrial parks, commercial buildings and infrastructure projects.

3. Main Features

1. High Integration & Compact Structure

The integrated high-voltage, low-voltage and transformation system occupies a small area with reasonable layout, eliminating the need for a large-scale power distribution room.

2. Ready-to-Use & Short Construction Cycle

Fully assembled, wired and debugged in the factory, the substation only requires basic fixation and cable connection on-site, significantly shortening the project period.

3. Safe & Reliable with Strong Protection

Equipped with comprehensive five-prevention interlocks, overload, short-circuit, leakage and lightning protection. The enclosure is corrosion-resistant, rain-proof, dust-proof and anti-aging.

4. Energy-Saving & Stable Operation

Configurable with SCB13 low-loss dry-type transformers or S13 oil-immersed transformers, ensuring high energy efficiency, low loss and low noise operation.

5. Maintenance-Free & Easy Operation

With a clear layout and convenient operation, it supports unattended operation and reduces long-term maintenance costs.

6. Strong Environmental Adaptability

Can operate stably for a long time in outdoor, humid, dusty, coastal and other complex environments.

7. Convenient Intelligent Expansion

Supports intelligent functions such as smart monitoring, remote communication, energy management and fault alarm.

4. Application Scenarios

• Urban residential quarters, commercial complexes, office buildings, schools, hospitals

• Industrial parks, factory workshops, mines, temporary power for construction sites

• Municipal roads, parking lots, subways, airports, ports and other infrastructure

• Urban-rural power grid renovation, outdoor transformer stations, scenic spots, development zone power distribution projects

• All types of power supply projects with high requirements for construction period, land occupation and safety
