Pre-fabricated Box Transformer Substation

Professional Product Details: ZG(F)S Series Prefabricated Substation (American Box Transformer)

Introduction: The ZG(F)S Series Compact and Flexible Combined Transformer, often referred to as the American-style Box Transformer, is a prefabricated substation that integrates transformer bodies, high-voltage load switches, protective fuses, and other components into a compact and fully insulated structure. This transformer is designed to meet the demands of modern power distribution with its space-saving design, ease of installation, and high reliability .

Structural Features:

1. Compact Integrated Design:

   • The American box-type transformer combines transformers, high-voltage load switches, fuses, and other equipment in a compact box, reducing the floor area and saving space, especially in urban substations and residential distribution rooms where space is limited .
   • The box body is made of a sturdy metal structure with good sealing and protection performance, generally reaching a protection level of IP33 or higher, preventing external factors such as dust and rain from affecting the internal equipment .

2. Oil-Immersed Structure:

   • Many American box-type transformers use oil-immersed transformers as the core component, which is beneficial for heat dissipation. The transformer oil conducts the heat generated by the iron core and windings to the tank wall and then dissipates it to the external environment, also playing an insulating role and improving the internal insulation performance of the transformer .

3. Layout of High-Voltage Side Equipment:

   • Inside the box, the high-voltage side is equipped with load switches and fuses. The load switch is used to cut off and connect the load current, which is convenient to operate and has a certain short-circuit protection ability. The fuse quickly cuts off the current in the event of a short circuit or other faults to protect the safety of the transformer and other equipment .

Technical Parameters:

1. Rated Voltage:

   • Common rated voltages on the high-voltage side are 10kV, 35kV, etc., adapting to the requirements of distribution networks of different voltage levels. The rated voltage on the low-voltage side is generally 0.4kV, mainly used to provide low-voltage power to the user side .

2. Rated Capacity:

   • The rated capacity range is wide, from several hundred kVA (e.g., 315kVA) to several thousand kVA (e.g., 2000kVA). Different rated capacities can be selected according to the actual size of the power consumption load .

3. Connection Group Label:

   • The connection group label is an important parameter for the transformer, affecting the voltage transformation ratio and phase relationship between the primary and secondary sides .

Product Advantages:

1. Smaller Volume:

   • The perfect combination makes the volume greatly reduced, which is equivalent to 1/3-1/5 of the equivalent European box transformer .

2. Lower Construction Cost:

   • The cost is less than half of the price of an electric house with the same capacity .

3. Transformer Characteristics:

   • The transformer has characteristics of low loss, low noise, environmental protection, high mechanical strength, good electrical performance, and strong overload capacity .

Applications: The ZG(F)S Series Padmount Transformer is widely used in residential areas, commercial establishments, industrial plants, and other sectors where reliable and consistent power supply is required .

Conclusion: The ZG(F)S Series Combined Outdoor Substation is a robust solution for modern power distribution needs, offering a compact, safe, and reliable alternative to traditional substations. Its versatility, efficiency, and adherence to international standards make it an ideal choice for a wide range of applications.
