Description

Box Type Prefabricated Substation description

The ZBW series combined substation, a classic Compact Prefabricated Substation also known as European-style pad-mounted substation, is an integrated power distribution device that integrates high-voltage electrical equipment, transformers and low-voltage electrical equipment into a compact whole. As a high-performance Box Type Prefabricated Substation, it is widely applied in urban high-rises, urban and rural buildings, residential communities, high-tech development zones, small and medium-sized factories, mining & oil fields and temporary construction power supply scenarios, undertaking the core task of electrical energy receiving and distribution in power distribution systems.

This Compact Prefabricated Substation features strong integration, small size, compact structure, safe and reliable operation, easy maintenance and good mobility. Compared with conventional civil substations, the same capacity Box Type Prefabricated Substation only occupies 1/10 to 1/5 of the floor area, which greatly reduces the design and construction workload of power distribution projects while cutting overall construction costs. The ZBW series Compact Prefabricated Substation is compatible with ring network, dual-power and radial terminal power distribution systems, and is a new type of integrated power equipment for the construction and renovation of urban and rural substations, while the Box Type Prefabricated Substation modular design further enhances its adaptability to diverse power distribution demands.

Compact Prefabricated Substation Operating Conditions

Altitude：The Compact Prefabricated Substation is suitable for installation at altitudes not exceeding 1000m, ensuring stable performance under standard altitude conditions of urban and rural power grids.
Ambient Temperature：The Box Type Prefabricated Substation operates in a temperature range of -25°C to +40°C, with a 24-hour average temperature not exceeding +35°C, adapting to different climate zones.
Outdoor Wind Speed：The Compact Prefabricated Substation can withstand outdoor wind speeds not exceeding 35m/s, with a robust structure suitable for outdoor open-air installation.
Relative Humidity：The Box Type Prefabricated Substation is applicable in environments with relative humidity not exceeding 90% (at +25°C), avoiding moisture-induced electrical faults.
Seismic Conditions：The Compact Prefabricated Substation resists horizontal acceleration ≤0.4m/s² and vertical acceleration ≤0.2m/s², meeting the seismic requirements of most urban and rural construction scenarios.
Installation Site：The Box Type Prefabricated Substation shall be installed in sites free of fire, explosion hazards, heavy pollution, chemical corrosion and severe vibration; customized solutions are available for special operating conditions upon consultation.

Compact Prefabricated Substation Main Technical Parameters

The ZBW series Compact Prefabricated Substation consists of high-voltage power distribution equipment, transformers and low-voltage power distribution equipment, divided into three independent functional compartments: high-voltage, transformer and low-voltage, with complete functions for the high and low-voltage compartments of the Box Type Prefabricated Substation.

High-voltage Compartment：The high-voltage side primary power supply system supports ring network, terminal and dual-power supply modes, and can be equipped with high-voltage metering devices to meet metering needs. The compartment has a compact and reasonable structure with a comprehensive "five-prevention" interlocking function to prevent misoperation, and all components of the Compact Prefabricated Substation are of reliable performance and easy operation.
Transformer Compartment：Optional low-loss oil-immersed transformers (S9, S11 series) or dry-type transformers (SC(B)9, SCR9, SC(B)10, SCR10 series) are available, and the compartment is equipped with an auto-start forced air cooling system and lighting system. The Box Type Prefabricated Substation can be configured with transformer rails as required, enabling easy transformer access and maintenance through double compartment doors.
Low-voltage Compartment：Can be designed as panel or cabinet structure according to user needs to form a customized power supply scheme, with integrated functions of power distribution, lighting distribution, reactive power compensation, electric energy metering and electrical quantity measurement. The flexible design of the Compact Prefabricated Substation meets diverse user demands, facilitating power supply management and improving power supply quality.

FAQ

Q: Can your intelligent combined box-type prefabricated substations be customized for special application scenarios, such as coastal areas or high-altitude regions?

Yes, we provide scenario-specific customization services. For coastal areas, we use marine-grade anti-corrosion steel plates and add salt-spray resistant coatings to the enclosure to withstand humid and corrosive environments. For high-altitude regions (above 1000m), we upgrade the insulation components and adjust the cooling system to compensate for low air pressure, preventing partial discharge risks. We can also customize the voltage level (6kV/7.2kV/12kV) and configure smart reactive power compensation modules to improve power factor for new energy integration projects.

Q: What core advantages do your intelligent combined box-type prefabricated substations have over traditional substations?

Our products integrate high-voltage switchgear, transformers, and low-voltage distribution units into one compact enclosure, which reduces the floor area by 60%~80% compared to traditional substations. The intelligent monitoring system enables real-time remote tracking of voltage, current, and temperature data, with automatic alerts for faults. Additionally, the on-load tap-changing function supports uninterrupted voltage regulation, ensuring stable power supply for industrial and residential loads. The prefabricated design also shortens on-site installation time from weeks to just 1-2 days, significantly cutting construction costs.
