Bu 500 kVA kompakt trafo merkezi is a fully integrated power distribution unit designed for medium-to-low voltage conversion in environments that demand space efficiency, fast deployment, and reliable performance. From industrial plants to real estate developments, this turnkey solution is increasingly favored for modern grid infrastructures.
500 kVA Kompakt Trafo Merkezi Nedir?
A 500 kVA compact substation, also known as a unitized substation or packaged substation, is a factory-assembled system that includes:
- A medium-voltage switchgear
- A distribution transformer
- A low-voltage switchboard
These components are enclosed in a weatherproof containerized housing, enabling easy transportation and rapid on-site installation. The unit typically converts 11kV or 33kV input to 400/230V output for distribution use.
Where Is It Used?
Thanks to its versatility and compact footprint, the 500 kVA compact substation is widely applied in:
- Kentsel altyapı (e.g., metro stations, street lighting)
- Industrial parks ve manufacturing plants
- Ticari binalar ve shopping centers
- Hospitals ve residential neighborhoods
- Renewable energy setups (e.g., solar farms, wind power)
Pazar Eğilimleri ve Arka Plan
According to reports from IEEE ve IEEMA, compact substations are gaining popularity due to rapid urbanization, growing energy demands, and the need for modular power solutions.
As defined by Vikipedi, substations form an integral part of the electrical transmission and distribution system. Compact substations offer a modern solution by combining essential components in one streamlined enclosure.
Additionally, as infrastructure projects adopt smart grid technologies, compact substations are being equipped with IoT sensors for real-time monitoring, fault diagnostics, and remote control capabilities.
