ZGS Modular Transformer Substation

American Type ZGS Prefabricated Substation

Comprehensive Product Review: ZG(F)S Series Combined Transformer (American Transformer)

Product Overview:

The ZG(F)S Series Prefabricated Substation, a standout in the field of electrical distribution, is an American Box Transformer that sets a new standard for compact and efficient power distribution solutions. This pre-assembled unit integrates the transformer, high-voltage load switch, and protective fuses into a single, compact enclosure, offering a streamlined approach to power distribution.

Technical Features and Benefits:

1. Integrated Design:

   • The ZG(F)S Series is a pre-assembled unit that consolidates the transformer, high-voltage load switch, and protective fuses into one enclosure, simplifying installation and reducing the physical footprint required for traditional substation setups.

2. Safety and Insulation:

   • The transformer features a fully insulated design, eliminating the need for additional insulation distances and ensuring the safety of personnel during operations. The high-voltage leads are fully insulated, enhancing safety further.

3. Compact Design:

   • The compact design of the ZG(F)S Series reduces the physical space required compared to traditional transformers, with a volume reduction to approximately 1/5 to 1/3 of that of similar box-type transformers.

4. Versatility:

   • The ZG(F)S Series is suitable for a wide range of applications, including new residential areas, green belts, parks, stations, docks, hotels, construction sites, and airports, making it a versatile solution for various power distribution needs.

5. Environmental Durability:

   • The transformer is engineered with a unique corrosion-resistant design and special paint treatment, making it suitable for use in harsh environments, such as areas with frequent storms and high pollution levels.

6. Low Maintenance:

   • The sealed design of the transformer reduces maintenance requirements, offering a cost-effective, 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, enhancing the reliability of the power distribution system.

8. Overload Capacity:

   • The ZG(F)S Series can handle overloads 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 Excellence:

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.
