CBW-12 series box-type substation is to counter high voltage, transformers, low voltage cabinet, the measurement unit and an intelligent system into a complete optimized intelligent set of device distribution. Apart from lessons in the structure of the domestic epidemic in European, American, made me change the merits, but also realize the power distribution automation technology. High-pressure side (10kV) to meet the electricity sector to the requirements of distribution automation, low-pressure side (0.4kV) to meet the intelligent intelligent residential property management requirements can be set up in Central Station or the property management office of the box-type PC substation for the "four distance" (telemetry, tele-hearing, tele-transfer, remote control) system management, intelligent multi-box-type substation to connect into a "hand in hand" ring when powered with the software, the fault section can be completed automatically location, fault removal, the load transfer zone, network reconfiguration and other functions, thus ensuring the restoration of a minute or so in power. CBW-12 series box-type substation, with a set of strong, functional and more reliable operation, good looks, safe and convenient; occupies less less maintenance, less investment and quick returns, long life and so on. Can be used for urban high-rise buildings, residential areas, municipal facilities, factories, mines, roads, docks, oil and electricity, such as temporary construction sites. CBW-12 compact box-type substation in addition to non-intelligent system, the other with the smart box-type substation. CBW-12 series box-type substation in line with GB/T17467-1998 "high-voltage / low voltage prefabricated substation", GB/T11022-1999 "high-voltage switchgear General technical conditions" standard. Materials in line with the cabinet material GBJ82-85, GB/T15231.1.3.4-94, GB10294-88 standard, IEC-1330 standards.
