ZGS Combined Transformer Station

Zgs Series Combined Box Transformer

Technical Product Profile: ZG(F)S Series Prefabricated Substation (American Box Transformer)

Executive Summary: The ZG(F)S Series Combined Transformer, recognized for its American-style box transformer design, is an advanced, compact, and integrated solution for power distribution. This product is engineered to optimize space utilization, enhance safety, and ensure operational efficiency in various electrical infrastructures.

Core Attributes:

1. Integrated Design:

   • The ZG(F)S Series combines the transformer, high-voltage switchgear, and protective devices into a single, compact unit, streamlining the installation process and reducing the footprint required for traditional substation setups.

2. Safety and Insulation:

   • The transformer is designed with a full-insulation structure, eliminating the need for additional insulation distances and providing a safer working environment for personnel. The high-voltage external leads are fully insulated, further enhancing safety during operations.

3. Compact and Efficient:

   • The compact design results in a significant reduction in size compared to traditional transformers, with the ZG(F)S Series occupying only 1/5 to 1/3 of the volume of similar box-type transformers.

4. Versatile Application:

   • The ZG(F)S Series Padmount Transformer is suitable for a wide range of applications, including new residential developments, green spaces, parks, transportation hubs, hospitality venues, construction sites, and airports.

5. Environmental Resilience:

   • The transformer is built with a unique corrosion-resistant design and special paint treatment, making it suitable for deployment in harsh environments, such as areas prone to storms and high pollution.

6. Low Maintenance:

   • The sealed design of the transformer reduces maintenance requirements, offering a low-cost, long-term solution for power distribution.

7. Dual Protection System:

   • The transformer is equipped with both insert-type and backup fuses, providing comprehensive protection against overloads and short circuits.

8. High Overload Capacity:

   • The ZG(F)S Series padmount transformer can handle overloads of up to 2 times the rated load for 2 hours and 1.6 times the load for 7 hours, ensuring continuous power supply even under demanding conditions.

Technical Specifications:

1. Voltage Ratings:

   • High-voltage side: 10kV to 35kV, adaptable to various distribution network requirements.
   • Low-voltage side: 0.4kV, standard for low-voltage power supply to end-users.

2. Capacity Range:

   • The series offers a wide range of capacities from several hundred kVA to several thousand kVA, catering to different load demands.

3. Connection Group:

   • The connection group label is crucial for determining the voltage transformation ratio and phase relationship between the primary and secondary sides of the transformer.

Operational Highlights:

1. High-Voltage Load Switch:

   • The high-voltage load switch is installed within the Transformer oil tank, allowing for a small form factor and 360° directional switching, ensuring reliable interruption of load current and high power supply reliability.

2. Cable Connections:

   • The transformer is designed for easy cable connections, with the option for live cable plugging and unplugging, which simplifies the connection process and reduces installation time and costs.

3. Investment Efficiency:

   • The compact and integrated design of the ZG(F)S Series reduces the need for a dedicated distribution room, lowering initial investment and installation expenses.
