The Hua-Type Box-Type Substation is designed for new energy power generation applications that require step-up transformation and compact power distribution equipment. The substation is divided into a high-voltage chamber and a low-voltage chamber by an internal partition inside the enclosure, while the transformer is arranged outside the enclosure.
The transformer is tightly connected to the substation enclosure through side outlet wiring. This structural design improves heat dissipation compared with conventional enclosed box-type substations and supports a clearer separation between the high-voltage and low-voltage functional areas.
The Hua-Type Box-Type Substation consists of a high-voltage chamber, a low-voltage chamber and a transformer. The high-voltage and low-voltage chambers are arranged inside the enclosure, while the transformer is placed outside the enclosure.
The transformer section is located outside the box-type substation enclosure. This is the main structural difference between the Hua-type design and traditional box-type substations.
The external transformer layout allows natural air to quickly carry away heat generated during transformer operation. This helps solve the heat dissipation problem of transformers installed inside conventional enclosed substations.
The transformer is tightly connected to the substation enclosure through a side outlet wiring method, supporting coordinated connection between the transformer and the high-voltage/low-voltage compartments.
An internal partition inside the enclosure divides the substation into a high-voltage chamber and a low-voltage chamber, supporting clearer functional separation and safer equipment arrangement.
The high-voltage side of the Hua-Type Box-Type Substation can flexibly adopt a vacuum circuit breaker or a combined electrical apparatus solution, such as a load switch and fuse combination.
Vacuum circuit breakers and combined electrical apparatus can be used as independent electrical units in 12kV and 40.5kV Hua-type box substations. The structure is rational, and the operation is simple and reliable.
The vacuum circuit breaker or combined electrical apparatus on the high-voltage side is equipped with mechanical interlock protection to help prevent misoperation.
The combined electrical apparatus can be equipped with signal transmission functions, making it convenient for background systems to monitor operation status in real time and support remote control functions.
Because this product may operate in relatively harsh environments, it has higher requirements for wind-sand resistance, heat insulation and heat dissipation. The protection grade should meet operating requirements and help protect internal components.
Protection Item | Requirement |
|---|---|
Transformer body | IP68 |
Substation enclosure | Not lower than IP54 |
The Hua-Type Box-Type Substation is suitable for new energy power generation projects that require step-up transformation and prefabricated power distribution equipment. Its external transformer design helps improve heat dissipation, while the high-voltage and low-voltage chamber separation supports a more organized equipment layout.
For new energy step-up applications, Huachen can provide product selection and configuration support according to project voltage level, high-voltage configuration, installation environment and power distribution requirements.
The Hua-Type Box-Type Substation is mainly used in new energy power generation step-up applications. It is suitable for projects that require a prefabricated substation structure with external transformer heat dissipation, high-voltage and low-voltage chamber separation, flexible high-voltage configuration and reliable enclosure protection.
Huachen is a leading manufacturer of prefabricated box substations with decades of R&D and manufacturing experience in the power transmission and distribution industry. We adhere to strict international quality standards for every production link, from material selection to finished product testing. Our team provides full-cycle support, including pre-sales project design, on-site installation guidance, and after-sales maintenance, with flexible production capacity to meet both bulk and custom project orders.
It is mainly used as a step-up box-type substation for new energy power generation applications.
The substation consists of three main parts: high-voltage chamber, low-voltage chamber and transformer.
The main difference is that the transformer section of the Hua-type structure is placed outside the substation enclosure. This helps improve transformer heat dissipation through natural air circulation.
The enclosure is divided into a high-voltage chamber and a low-voltage chamber by an internal partition inside the box-type substation.
The high-voltage side can adopt a vacuum circuit breaker or a combined electrical apparatus solution, such as a load switch and fuse combination.
Yes. The combined electrical apparatus can be equipped with signal transmission functions, making it convenient for background systems to monitor operation status and support remote control.
The transformer body protection grade is IP68, and the enclosure protection grade is not lower than IP54.
