What Are The Common Models Of Prefabricated Substations?

Common models of prefabricated substations are mainly named according to voltage level, structural design, and application scenario. Different manufacturers may have slightly different naming rules, but they generally follow industry-standard specifications. The following are some mainstream models and their characteristics:

 

YBM Series (European-style box-type substation)

Representative models: YBM-12/0.4, YBM-24/0.4

Voltage level: 12kV or 24kV on the high-voltage side, 0.4kV on the low-voltage side

Applicable scenarios: Urban power distribution, industrial parks, residential communities

Features: Adopts a three-compartment structure (high-voltage room, transformer room, and low-voltage room) for convenient maintenance.

Configurable with ring network power supply and dual power supply modes, supporting intelligent monitoring systems.

Protection level up to IP54 or higher, suitable for complex outdoor environments.

 

YB□-12 Series (General Model for European-Style Substations)

Representative Models: YB-12/0.4-630, YB-12/0.4-1000

Numerical Meaning: The suffixes "630" and "1000" indicate the transformer's rated capacity (kVA).

Technical Parameters:
Rated Voltage: High Voltage 12kV / Low Voltage 0.4kV
Capacity Range: 50kVA～2500kVA
Standards: GB/T 17467, IEC 601330
Application Areas: High-rise buildings, high-tech development zones, temporary construction power supply, etc.
