Introduction
The ZGS Series American Type Prefabricated Substation is an advanced, compact, and cost-effective power distribution solution designed for urban and rural power distribution networks. Manufactured by Shenheng Power Equipment Co., Ltd., this substation integrates high-voltage control, protection, power transformation, and distribution into a single unit.
This prefabricated Compact Substation guide features an oil-immersed transformer, where the high-voltage load switch and fuse are installed directly inside the transformer oil, reducing external components and enhancing safety and efficiency. Its compact design and high performance make it ideal for power plants, industrial areas, commercial buildings, and urban infrastructure projects.
Key Features
✔ Compact Structure – The ZGS substation occupies 1/3 to 1/5 of the space required by a conventional European-style substation of the same capacity.
✔ Fully Sealed and Insulated – Eliminates the need for insulation clearance, ensuring personnel safety.
✔ Flexible High-Voltage Connection – Can be used in both looped network and terminal configurations for enhanced reliability.
✔ High-Performance Transformer – Features low loss, low noise, high overload capacity, strong impact resistance, and excellent short-circuit resistance.
✔ Multiple Cable Connection Options – Supports both 200A elbow connectors and 600A T-type fixed cable connectors, with optional ZnO lightning protection.
