HYB New Energy Prefabricated Substation (Chinese Type Box Substation)-Zhejiang Huapu Electric Co., Ltd.

HYB New Energy Prefabricated Substation (Chinese Type Box Substation)

The HYB New Energy Prefabricated Substation, also known as the Chinese Type Box Substation, is a compact, integrated power distribution unit that combines high-voltage switchgear, transformer, and low-voltage distribution equipment in one enclosure. It is designed to meet modern power distribution needs in urban, industrial, and renewable energy settings. This substation is engineered for efficient and stable power transformation and distribution in a wide range of environments.

Product Advantages
Compact Design
We design the substation with a space-saving layout, combining multiple components within a single structure. This minimizes land usage and facilitates installation in space-constrained areas such as city centers and industrial zones.

Modular Construction
The modular design allows for flexible configuration and customization based on specific site requirements. Each module functions independently and can be upgraded or maintained without disrupting the entire system.

Enhanced Safety Measures
Our substation integrates multiple protection systems, including high-voltage interlocks, temperature monitoring, and fault isolation. These features contribute to the safe operation and help reduce potential risks during daily use.

Ease of Transportation and Installation
The prefabricated nature of the unit simplifies transportation and installation. It arrives at the site as a fully assembled or semi-assembled structure, significantly reducing on-site labor and setup time.

Low Maintenance Requirements
We use high-quality, weather-resistant materials and advanced components that require minimal maintenance. Routine inspections are simplified due to the accessible layout of all internal parts.

Product Features
Integrated System Architecture
The substation integrates high-voltage, transformer, and low-voltage sections into a unified enclosure. This integration ensures coordinated operation and contributes to overall system reliability.

Weatherproof Enclosure
Constructed with corrosion-resistant steel and coated with anti-rust paint, the outer shell is suitable for outdoor installations. It offers protection against moisture, dust, and ultraviolet exposure.

Thermal Management System
We include an advanced ventilation and cooling system, ensuring stable internal temperatures even under high load conditions. This feature helps prolong the lifespan of internal components.

If the user places an order, they need to provide the following information:

◇ Altitude: s 2000m, please indicate it first when ordering;

◇ Environmental temperature:-25℃~+40 ℃;

◇ Relative humidity: The daily average value shall not exceed 95%, and the monthly average value shall not exceed 90%;

◇ Seismic resistance level: horizontal acceleration 0.4m/s', vertical acceleration 0.15m/s²;

◇ The installation site is free from severe impact, serious pollution, chemical corrosion, and the risk of conductive dust explosion in Egypt. When normal usage conditions cannot be met, please consult with our company to resolve the issue.

◇Intelligentization: An intelligent monitoring unit is installed internally, which has functions such as monitoring, protection, remote control, and video monitoring, meeting the requirements of users for remote control and real-time data monitoring of the box transformer.
◇Environmentally friendly: Vegetable oil (FR3) can be used inside the transformer, with a ignition point above 360 C and a natural degradation rate of over 90%, which is stronger than mineral oil transformers in terms of overload capacity.
◇Strong environmental adaptability: IP54 shell protection, multiple anti-corrosion design, dehumidification scheme combined with heating dehumidifier and axial flow fan, can adapt to various harsh natural environments such as humidity and heavy salt mist.
◇Excellent electrical performance: The short-term withstand parameters of the high-voltage vacuum circuit breaker can reach 31.5kA/4S, which better meets the increasing demand of customers for the capacity of a single box transformer.
◇Innovative structural design: A drainage device can be installed on the top of the box of the Huashi box transformer, which can prevent the blades from falling due to ice and damaging the box and transformer radiator.
