Brief introduction to the products


Brief introduction to the products


With the continuous development of the social progress, China's urban power grid has changed dramatically.  Most cities have formed or are forming a large number of electricity load-up areas. Past 10kV line from the substation (or branch line) to the direct  user's power supply has been difficult to meet the requirements of urban development, which resulted in a new form of power supply - through the switching substation to supply the users with power. However, with the degree of urban density increases, the original construction of the switching substation is limited by the land and the urban planning, therefore a more advanced and practical power distribution equipment - small-scale outdoor intelligent switching substation (outdoor ring cabinets) appeares. This intelligent switching substation without construction covers only a small area with a very flexible configuration. The power supply is more reliable. The time for installation and debugging is greatly shortened to reduce the overall cost.
With the development of modern industry, the requirements for automation and intelligence computerization of the electrical equipment are becoming higher and higher.  The utilization of the technology of modern electronic, sensor, communications or computer and network to make the mornitoring, protection, control or measurement under the normal or accident conditions of the electrical equipment for better management into the status of integration has become an inevitable trend and direction of development.
The intelligent small substation (outdoor ring cabinet) is designed on the basis of European substation programs, which installs the 10kV switchgear, circuit breakers, load switches, current CT, voltage transformer PT, substation FTU, RTU and communication control terminal (CCU, 10kV metering, automatic copy table, UPS power supply and the indicators) in a movable sealed anti-moisture stainless steel tank to realize the integration of the primary and secondary system and the modularization of the assembly. The construction period is shortened. The reliability of the urban power grid operation is greatly enhanced.
