ZGS-24/0.4 American-style Box-type Transformer Substation

ZGS-24/0.4 American-Style Pre-installed Substation (Packaged Substation) is specially designed to meet modern power distribution demands. It features a compact size, lightweight, low noise, low loss, and high reliability, making it a full replacement for imported products. It is widely applied in residential communities, commercial centers, light rail stations, airports, industrial and mining enterprises, hospitals, schools, and other locations.

Core Product Advantages:

Compact Structure and Flexible Installation
The ZGS-24/0.4 adopts a highly integrated design with a small footprint and flexible layout, making it especially suitable for urban load centers and areas with tight power supply requirements.

Fully Sealed and Insulated for Enhanced Safety
The high-voltage side features a fully insulated and sealed structure that effectively prevents misoperation, ensuring the safety of maintenance personnel. The enclosure boasts excellent protection performance with a high protection rating, capable of adapting to various complex environments.

Dual Fuse Protection System for Efficiency and Economy
Equipped with a combined protection scheme of current-limiting fuses and plug-in dual-element fuses (sensitive to both current and temperature), the system responds rapidly to faults, reduces fault impact scope, improves operational reliability, and significantly lowers maintenance costs.

Compatible with Ring Network or Terminal Systems
Designed for both terminal power supply systems and ring network configurations, offering flexible adaptation to different distribution schemes and easy expandability.

High-Voltage Cable Plug-in Design for Convenient Operation
Utilizes cable plug connectors with isolation functions, enabling safe and convenient live-line operations, which enhances on-site installation and maintenance efficiency.

Low-Noise, Low-Loss Transformer Core
Equipped with high-performance three-phase three-limb or three-phase four-limb transformers, providing excellent short-circuit and overload resistance for more stable operation.

Environmentally Friendly and Weather Resistant
Uses high flash point insulating oil; the transformer and enclosure surfaces undergo “three-proof” treatment (moisture-proof, mildew-proof, salt spray-proof), allowing long-term stable operation in harsh environments such as humidity, salt spray, and dust.

JB/T 10217 — Combined Transformer (or Modular Transformer)

The ZGS-24/0.4 American-style combined transformer is constructed from high-quality metal sheets, precisely shaped by CNC equipment to ensure high structural strength, excellent sealing performance, and good corrosion resistance. The overall structure is compact and divided into two functional areas: the high-voltage room and the low-voltage room, with the transformer body located at the back of the high-voltage room, effectively optimizing the footprint.

The design of the ZGS-24/0.4 box-type transformer adheres to American standards and features a small size, compact structure, and convenient operation and maintenance. It is particularly suitable for urban distribution networks, grid renovations, industrial and mining enterprises, and residential communities, providing a safe, stable, and efficient power distribution solution.
