Product Description

Product Description

Prefabricated Substation

Shengxian Electric Power Technology manufactures prefabricated substation is a compact, complete set of power distribution equipment that integrates high-voltage switchgear, power transformer, and low-voltage distribution equipment into one enclosure according to specific wiring schemes. It is widely used in urban grid renovation, residential communities, high-rise buildings, industrial and mining enterprises, hotels, shopping malls, airports, railways, oil fields, ports, highways, and temporary power facilities.
 
With its compact structure, high reliability, and minimal on-site installation requirements, this substation occupies only 1/10 to 1/5 of the land area required by traditional civil-constructed substations of the same capacity, significantly reducing construction costs.

Key Features

Compact & Modular Design
Integrates HV, transformer, and LV sections in one enclosure, saving up to 60% space compared to traditional substations.

European Standard Configuration
Conforms to IEC 61330, GB/T 17467, and other international standards. Typical arrangement: HV load break switch + transformer + LV main breaker.

High Safety Level
Equipped with mechanical interlocks, SF6 insulated switchgear (optional), and anti-fault protection. IP33/IP34 enclosure protection ensures personnel safety.

Weatherproof & Durable
Galvanized steel + anti-corrosion coating. Suitable for outdoor installation in harsh environments (rain, dust, salt fog).

Easy Installation & Maintenance
Factory pre-assembled and tested. Only requires a simple foundation and cable connection on site. Removable panels allow easy access for maintenance.

Optional Features

Temperature & humidity control (heater / fan)
Remote monitoring (SCADA ready)
Oil-immersed or dry-type transformer
Smart metering & communication ports (RS485 / Ethernet)

Application

Residential communities & villa areas

Commercial buildings & shopping malls

Industrial plants & mining sites

Wind / solar power plants

EV charging stations

Temporary construction power supply

Rural & urban grid upgrading projects
