box-type substation
Product Overview
A Substation, also known as a Switchgear Cabinet, is a compact, integrated set of power distribution equipment that includes high-voltage switching equipment, distribution transformers, and low-voltage distribution devices. These substations are typically prefabricated in a factory and transported as a complete unit to the installation site, offering advantages such as rapid deployment, minimal land use, and easy relocation. They are suitable for three-phase AC systems with a rated voltage of 10/0.4KV and are mainly used for power transmission and distribution, particularly suitable for urban power grid construction and renovation.

Features of Substation Cabinets
- Compact Design: Due to its compact design, the substation cabinet is suitable for use in areas where space is limited.
- Factory-Manufactured: Prefabricated in a factory, ensuring production quality and accelerating on-site installation speed.
- Aesthetically Pleasing: The substation cabinet’s appearance is designed to blend with the surrounding environment, offering good aesthetics.
- High Adaptability: It features interchangeability and is easy to standardize and series-produce, with minimal maintenance required, saving on investment.
- Environmental Protection: Its fully enclosed structure has a smaller impact on the environment.
Classification of Substation Cabinets
Substation cabinets come in various models and classifications, which can be selected according to different needs. For example, European-style and American-style substations are two common types. European-style substations are usually larger, housing both the transformer and high and low voltage switches within a single large casing, while American-style substations incorporate the high and low voltage distribution equipment into the transformer oil tank, resulting in a smaller volume and relatively better heat dissipation.
Structure of Substation Cabinets
The structure of a substation cabinet typically includes a high-voltage room, transformer room, and low-voltage room, which can be arranged in a straight line or in other configurations as needed. The cabinet is usually made of steel sandwich panels or composite boards, offering good rain protection, and may feature ventilation holes and insulation measures to prevent the internal temperature from becoming too high.
The intelligence of substation cabinets is also an important direction for future development, and with technological advancements, their functionality and performance will be further enhanced. Due to their efficiency, flexibility, and economic nature, the application of substation cabinets in urban and rural power grids will become increasingly widespread.
