1. Product overview

Substation with transformer US style housing ZGS11-10 is a pre-assembled, universal distribution block developed by Xinda Transformer for cable distribution networks. It integrates high-voltage control, protection, voltage conversion and power distribution equipment, making it ideal for urban and rural power grids, residential areas, commercial centers, industrial and mining facilities, and municipal engineering projects.

Main design features:

• To enhance safety, high-voltage load switches and fuses are directly immersed in transformer oil.

• Fully sealed design with built-in monitoring components (oil temperature sensor, oil level sensor, pressure gauge, relief valve, oil drain valve) to monitor operating status in real time.

• Supports three power supply modes: ring grid, terminal and power supply, adapting to the actual needs of China's power grid.

• Customization options include standard, heavy-duty, and reinforced outer casing options, as well as plug-in and standard design solutions to meet the diverse needs of low-voltage outlets of varying complexity.

5. Product benefits

1. Integrated design, space saving.

   Pre-assembled high-voltage, transformer, and low-voltage equipment eliminates the need for additional on-site wiring, reducing installation time. It occupies only 1/3–1/5 of the space of traditional substations, significantly reducing infrastructure costs.

2. Fully sealed design, high reliability.

   High-voltage components, immersed in transformer oil and fully sealed, provide superior protection against moisture, dust, and condensation, adapting to harsh environmental conditions. They boast a long, maintenance-free service life and reliable operation.

3. Comprehensive protection, easy to maintain.

   Equipped with high-voltage fuses and load break switches for effective protection against overloads and short circuits. For safety, when replacing a fuse, the breaker must first be disconnected. Reserved maintenance interfaces simplify daily operation and repairs.

4. Customizable selection, highly adaptable

   Multifunctionality, a multi-variant design, and the option to select the housing allow for the customization of component specifications and housing colors, thereby satisfying diverse power supply requirements across various scenarios through a flexible and cost-effective selection.

5. High energy efficiency, compliance with national standards.

   The design utilizes high-quality iron cores and winding materials with low no-load and on-load losses, ensuring exceptional energy efficiency. It complies with national energy efficiency standards, reducing long-term energy costs.

6. Requirements for installation, operation, maintenance and ordering.

(1) Installation and operation

• After lifting and installation, tighten the anchor bolts, connect the incoming/outgoing lines and conduct a thorough inspection before applying power.

• Before replacing high voltage fuses, first turn off the breaker, then open the door to operate. Operation under voltage is strictly prohibited.

• When performing maintenance, first turn off the power supply and perform the work strictly in accordance with the operating instructions.

(2) Order requirements

When placing an order, please specify the product model, specifications, quantity, and the model/specifications/paint color of the electrical component outer casing. For special application requirements, please notify us in advance when placing your order.

7. Applicable scenarios
