The ZGS Combined Box-Type Transformer is an independent complete power distribution device used in AC 50Hz, 6–10kV power grids. It is available with rated capacities from 30kVA to 1600kVA and can be used for both outdoor and indoor applications.
The product combines transformer body, switchgear, fuse, tap switch, low-voltage distribution equipment and related auxiliary devices into one compact transformer system. It is widely used in industrial parks, urban residential communities, commercial centers, road lighting systems, high-rise buildings and temporary construction sites.
With compact structure, small footprint and convenient installation, the ZGS transformer provides a practical power distribution solution for projects requiring flexible connection, reliable operation and efficient space use.
The transformer has a small size, compact structure and small footprint. It is convenient to install and suitable for projects where installation space is limited.
The product is designed with low loss, low noise and low temperature rise. It also has strong overload capacity beyond nameplate rating and good resistance to sudden short-circuit impact.
The ZGS transformer adopts a fully sealed and fully insulated structure, supporting safe and reliable operation in power distribution applications.
The connection mode is flexible. The product can be used in terminal power supply systems or ring network power supply systems. The conversion is convenient and helps improve power supply reliability.
The equipment is easy to operate and maintain. Its prefabricated structure supports a shorter production cycle and lower project construction cost.
The product follows relevant standards for combined transformers and operating conditions, including JB/T 10217-2013 and DL/T 1267-2013.
