Product Description
1.
Product Overview
ARSM16-12/24 Sulfur Hexafluoride Fully Insulated Compact Metal Enclosed Switchgear (hereinafter referred to as Sulfur Hexafluoride Inflatable Cabinet) is a ring net cabinet suitable for three-phase AC power system with rated voltage of 12/24 kV and rated frequency of 50/60 Hz. All components are subject to modular design, with flexible configuration and expansion scheme, compact product structure, comprehensive distribution automation scheme, control, segmentation, transformation and protection of lines.It is suitable for areas with large power supply load and high density, such as residential areas, production, power supply, large public buildings, switching stations, industry and commerce, villages and towns, etc. It has the advantages, such as safe use, no wind and rain, convenient installation, locality, less maintenance, high reliability and high utilization rate.
This series of ring net cabinets are mainly designed according to GB3906, IEC298, IEC62271-1 and IEC62271-200.
