European-style box substation

Y(Z)B-12/0.4 series pre-installed substations are outdoor complete distribution devices used for 6-10kV ring network or radial power supply systems. The product combines high-voltage switchgear, power transformers, and low-voltage switchgear, installed in a closed box to form an independent substation accessible to the public. Our company offers a wide range of products, which can be selected as European-style box transformers and American-style box transformers based on product type, and can be chosen as flat, sunken, or semi-buried based on functionality. The shell can be made of metal stainless steel, cold plate, composite board, GRC cement, anti-corrosion wooden strips, and other landscape products.

Product Overview

This series of products is suitable for 10KV (6KV) AC 50Hz substations, integrating high-voltage switchgear and low-voltage switchgear into a distribution device. It has advantages such as small footprint, simple and safe installation, and convenient maintenance. It can be directly connected to the load, achieving power supply with one-time installation. Multiple combinations can form different power supply methods, thus widely used in named communities, high-rise buildings, tourist attractions, highways, industrial and mining enterprises, oilfield docks, rural power grids, and other places.
