It integrates medium voltage switchgear, distribution transformer and low voltage distribution panel into three independent fire-isolated compartments inside one weatherproof enclosure, realizing full functions of voltage transformation, power distribution, electric energy metering and reactive power compensation. Different from traditional civil-built substation, this compact design saves over 70% construction space, shortens on-site installation cycle and cuts overall project investment greatly, becoming mainstream distribution equipment for global urban grid and new energy projects.
Core Technical Parameters
Rated Frequency: 50Hz/60Hz (custom for global markets)
Protection Grade: Standard IP54, upgraded IP55/IP65 for coastal & dusty corrosive environment
Enclosure Material: Galvanized steel, aluminum zinc plate or stainless steel; anti-rust & anti-corrosion service life ≥20 years, customizable exterior color matching urban landscape
Working Ambient: -40℃ ~ +55℃, altitude ≤1000m, rainproof, dustproof and anti-small animal intrusion
Certification: CE, ISO9001, CB, IEC test certification, meet EU access standard
Three Major Advantages
Three-chamber isolated safety design: Fireproof partition separates each room, maintenance on one compartment while other circuits remain energized, greatly reduce short-circuit & fire risk
Fast installation: Finished wiring & debugging in factory; only foundation laying and cable connection on site, construction period reduced by 60%~70% vs traditional substation
Space-saving : Compact layout can be installed beside load center, reduce cable loss; customizable shell color fits residential district, park and city street layout.
