ZGS-13 Prefabricated Substation

1. Product Overview

ZGS-13 series combined substation (American type) adopts S13 grade energy-saving iron core and coil design. It is a compact complete set of equipment developed for urban and rural power grid transformation and various power distribution scenarios. It integrates transformer body, high-voltage load switch, fuse and other components into one, with fully sealed oil-immersed insulation. Pre-installed in the factory, it can be flexibly used outdoors and indoors to efficiently realize voltage transformation and power distribution, adapt to ring network, terminal and dual power supply modes, replace imported products, and operate stably and reliably.

2. Model Meaning (Model Composition Diagram)

ZGS - 13 - □(H/Z) / □ / □

• ZGS: Combined Substation (American type, core category)

• 13: Performance level code (representing S13 energy efficiency level, low-loss design standard)

• □(H/Z): High-voltage wiring scheme (H=Ring Network Type, Z=Terminal Type)

• First □: Rated transformer capacity (Unit: kVA, such as 100, 315, 630, etc.)

• Second □: Rated high-voltage voltage (Unit: kV, such as 10, 6)

• Third □: Rated low-voltage voltage (Unit: kV, such as 0.4)

3. Product Features

• Energy-saving and Low-loss: S13 energy efficiency standard, the iron core adopts high-quality silicon steel sheet step-lap process, and the coil is made of high-conductivity copper material, which greatly reduces no-load and load loss, making long-term operation more energy-saving and meeting national energy efficiency requirements.

• Compact and Space-saving: Its volume is only 1/3-1/5 of that of European-style substation with the same capacity, covering a small area, light weight, flexible movement, convenient installation, no complex on-site construction, suitable for space-constrained scenarios.

• Safe and Reliable: Fully sealed and insulated structure, high-voltage load switch and fuse are placed in transformer oil, with dual-sensitivity fuse (temperature and current) double protection, effectively ensuring personal safety, stable operation and simple maintenance.

• Flexible Adaptation: Supports three power supply modes: ring network, terminal and dual power supply. High-voltage incoming line adopts cable connector structure, flexible operation, and can be customized with wiring schemes, protection levels and high-altitude adaptation according to needs to cope with complex environments.

• Strong Durability: The shell is treated with "three-proof" (dustproof, waterproof, corrosion-proof), adopts high-flash point insulating oil, has excellent sealing performance, moisture-proof, salt spray-proof and corrosion-proof, adapts to various complex outdoor environments, has a long service life and convenient maintenance.
