Product Description

Product Description

General introduction:

SF6 gas filled switchgear Intelligent switching station (outdoor ring network cabinet) 
Short Description: 
*Intelligent switching station (outdoor ring network cabinet) using 12kV / 24kV /35KV switchgear, circuit 
breaker, load isolating switch, current transformer, 12kV / 24kV power PT, to block DTU FTU,PTU, 
communication control terminal (CCU), 12kV / 24kV/35KV metering and automatic meter reading. 
*The UPS power supply and indicator instruments are installed into a sealed moisture-proof stainless steel 
box with a moving shell, thus realizing the integration of the primary and secondary systems of the urban 
distribution network, the modularization of assembly, shortening the construction period and greatly improving 
the reliability of the operation of the urban power network.

*Switchgear is modular unit mode, which can be combined according to different uses. It can be divided 
into fixed unit combination and expandable unit to meet the flexible use of compact switchgear in various 
substations.

*• SF6 gas filled switchgear Intelligent switching station is a fully sealed system, all its live components and 
switches are enclosed in stainless steel housing.

*SRM16-12 type inflatable switchgear is divided into non-expandable standard configuration and 
expandable standard configuration. Because of the combination of full module and half module and its 
scalability, it has very special flexibility

*SRM16-12 inflatable switch implements GB standard. The design life of operation under indoor conditions 
(20 C) exceeds 30 years.
