Transformer Substation
01
Prefabricated Substation (Chinese Box Type)
Features
1. Compact Structural Design
Adopting a modular integrated layout, it occupies 40% less floor area than traditional compact substations, ideal for space-constrained scenarios like urban centers and scenic areas.
2. High-Strength Protective Enclosure
Manufactured from premium steel with IP54 protection rating, it is impact-resistant and corrosion-proof, suitable for complex outdoor environments.
3. Easy Maintenance
With zoned layout of internal electrical components and reserved maintenance access, maintenance efficiency is improved by 50%.
4. Flexible Power Supply Solution
The high-voltage side supports multiple configurations such as ring main units/circuit breaker cabinets, adapting to different power demand scales.
5. Efficient Heat Dissipation System
Featuring intelligent temperature-controlled exhaust design, it operates stably in environments ranging from -25℃ to +40℃.
Operating conditions
● Ambient Temperature: -25°C to +40°C
● Altitude: ≤2000m
● Relative Humidity: Daily average ≤95%, monthly average ≤90%
● Seismic Resistance: Horizontal acceleration 0.4m/s², vertical acceleration 0.15m/s²
● Installation Environment: Free from severe shocks, heavy pollution, chemical corrosion, conductive dust, or explosive hazards.
Note: In case of non-compliance with normal operating conditions, please consult our company for solutions.
