Product Overview

Prefabricated cabins are outdoor intelligent substations based on the core concept of "standard distribution". The adoption of prefabricated cabin structures has become an important measure for the construction of secondary equipment carriers in intelligent substations. With the acceleration of the construction of smart grids, the speed of substation construction is relatively lagging behind. In order to accelerate the construction cycle of smart substations, State Grid Corporation of China has proposed a standard distribution type substation construction model, which achieves rapid promotion and practical application of smart substations (prefabricated cabins) through the scheme of "standardized design, factory processing, and prefabricated construction". Prefabricated cabins are an important manifestation of new technologies, materials, and equipment applied in intelligent substations. They are composed of prefabricated cabins, secondary equipment cabinets (or racks), cabin auxiliary facilities, etc. They are manufactured, assembled, wired, debugged, and transported as a whole to the construction site, located on the installation foundation. The prefabricated cabin and its internal secondary equipment are integrated by the manufacturer to achieve factory processing, reduce on‑site secondary wiring, decrease design, construction, commissioning, workload, simplify maintenance work, shorten construction period, and effectively support the rapid construction of the power grid. Prefabricated cabins have the technical characteristics of standardization, modularization, and prefabrication. Manufacturers can customize specific sizes according to the actual needs of the equipment cabinet to adapt to the normal operation of the equipment. Standardization refers to the reference of the size of prefabricated cabins to the size of standard containers and appropriate improvements, in order to make them as perfect and standardized as possible, in accordance with the adoption of equipment, and to achieve corresponding standardization in order to facilitate the normal operation of equipment more effectively; Modularization refers to the division of prefabricated compartments into modules such as public equipment prefabricated compartments, interval equipment prefabricated compartments, AC/DC power prefabricated compartments, and battery prefabricated compartments based on the different functions of internal equipment. Different modular prefabricated cabins can be divided into several sub modules based on the voltage level; Prefabrication refers to the factory prefabrication of the cabin structure, internal equipment installation, wiring between internal equipment, and cables and optical cables between internal equipment. And complete the installation, wiring, and debugging of all equipment in the factory, transport the prefabricated cabin and its internal equipment as a whole to the substation site, complete the positioning and power on, thereby improving on‑site construction efficiency and achieving the goal of reducing the construction cycle of smart substations!
