Product introduction
This product is absorbed the latest advanced technology from abroad，combined with the actual situation in China，the whole product has the characteristics of small size，simple installation and maintenance，low noise，low loss，anti-theft，strong overload capacity，full protection and so on.It is suitable for new residential area，green belt，park，station hotel，construction site，airport and other places.
ZGS11-12 series American preinstalled box substation，suitable for 10kV ring network power supply，dualpower supplyor terminal power supply system，as a transformer，metering，compensation control and protection device.
This product meets the following standards：Pre-instaled high-voltage and low-voltage substation DL/t537-2008 technical conditions for ordering 6-35kV box-type substation
Types of meaning
Normal service environment
◆ the altitude shall not exceed 1000m
◆ambient temperature:-35℃-+40℃
◆relative humidity: daily average is not more than 95%, monthly average is not more than 90%
◆ installation place: no fire, explosion, chemical corrosive gas and well-ventilated place, the ground tilt Angle is not more than 3º
Functions and features
◆full insulation, full seal, less maintenance, reliable guarantee of personal safety
◆compact structure, volume is only 1/3 to 1/5 of the same capacity of European variation height low
◆sub box structure can be used to avoid oil pollution in the transformer tank,
◆double fuse full range protection is adopted on the high-pressure side, which greatly reduces the cost
◆ both can be used for ring network, but also for the terminal, the cable head can be emergency plug and pull in 200A load current
◆ the box adopts the honeycomb type double sandwich composite plate, with the function of temperature insulation and heat dissipation
◆the low-voltage side is equipped with an electronic phase loss protector, which can quickly break the main forward switch Then abnormal voltage occurs in the system
◆ high pressure side oil-immersed load switch or SF6 load switch can be electrically upgraded to lay a foundation for therealization of distribution network automation
◆adopt oil-immersed S9 or S11 series transformers with better performance
