Product Description

Product Overview

The 10kV State Grid Replacement Prefabricated Substation (Non-Metallic Type) is suitable for distribution projects where existing American-style box transformers need to be replaced without major changes to the original foundation. It combines compact structure, complete functional configuration and convenient installation in one prefabricated substation system.

The product adopts a compact multi-compartment grid layout. It can be configured as a terminal-type or ring-network-type power supply system. From left to right, the standard structure includes the high-voltage room, transformer room and low-voltage room. According to intelligent substation requirements, it can also be equipped with a metering room, data acquisition room and DTU room, forming a compact substation with up to six functional compartments.

The non-metallic enclosure type is suitable for power distribution applications requiring compact installation, foundation compatibility, functional integration and reliable outdoor operation.
