Product Features
This series of products is independently designed by our company on the basis of ZGS combined transformers to meet the needs of urban and rural power grid construction.
It features small size, compact structure, short on-site installation and commissioning period, and can replace traditional substations (stations).
It can also meet various configuration requirements such as user power metering, reactive power compensation, and high and low voltage schemes, representing the development direction of small and medium-sized substations (stations).
This product is suitable for industrial and mining enterprises, stations, wharfs, airports, public places, high-rise buildings, and residential areas with 10kV, 50Hz, 30~1600kVA power users. It is applicable to both ring network power supply and terminal power supply.

With a small size, compact structure, and short-term of on-site installation and commissioning, it can replace the traditional substation (station). It can also meet configuration requirements of various programs such as the user power metering, reactive power compensation, high and low voltage schemes, representing the development direction of various medium-sized substations (stations). This product is suitable for industrial and mining enterprises, station, wharf, airports, public places, high-rise buildings and 10kv, 50Hz, 30~1600kVA power users in residential areas, applying for not only power supply network but also for terminal.
Product Overview
Combined Substation
A combined substation is a complete set of equipment that has been assembled and passed type tests. Its main components include transformers, high-voltage switchgear and control equipment, low-voltage switchgear and control equipment, corresponding internal connection lines (cables, busbars, etc.), and auxiliary equipment.
The combined substation can be operated from inside or outside through cable connections, and can be installed on the ground or underground (partially or fully).
