YB-12/24 High-Voltage/Low-Voltage Prefabricated Substation


The YB-12/24 series of high-voltage/low-voltage prefabricated substations (hereafter referred to as "box-type substations") are compact, fully assembled distribution units that integrate high-voltage switchgear, transformers, low-voltage switchgear, and other components. Designed for use in three-phase AC systems, they serve as comprehensive equipment for both receiving and distributing electrical power. These substations offer a range of advantages, including a small footprint, minimal land requirements, cost-effectiveness, a compact design, ease of relocation, short installation timelines, high reliability, and an aesthetically pleasing appearance—making them ideal for applications such as urban public power distribution, street lighting systems, industrial and mining enterprises, high-rise buildings, residential communities, oil fields, port facilities, and construction sites.


Product Details


Product Overview
The YB-12/24 series of high-voltage/low-voltage prefabricated substations (hereafter referred to as "box-type substations") are compact, fully assembled distribution units that integrate high-voltage switchgear, transformers, low-voltage switchgear, and other components into a single, space-efficient package. Designed for use in three-phase AC systems, these substations serve as comprehensive devices for both receiving and distributing electrical power. They offer a wide range of advantages, including small footprint, minimal land occupation, cost-effectiveness, a compact design, ease of relocation, short installation timelines, high reliability, and an aesthetically pleasing appearance—making them ideal for applications such as urban public power distribution, street lighting systems, industrial and mining enterprises, high-rise buildings, residential communities, oil fields, port facilities, and construction sites.
