Product Description

Medium Voltage Indoor Air Insulated Switchgear Cabinet Sf6 Switchgear
 

Product Description
GSM type RMU with SF6 load switch as main switch,the whole switchgear is suitable for electric distribution automation, it's compact also expandable metal-enclosed switchgear.Features in its simple structure, flexible  operation, reliable interlocking and convininent installation etc.
It meets IEC298, IEC60420, IEC60265, GB 3906, GB3804, GB16926 standards. The switchgear has reliable fault operation prevention function.

Features
SF6 gas is adopted as insulating and arcing medium. The arcing mode is constant magnetic field rotating arc, so its arcing ability will not be affected by magnitude of arc and current. Besides, it has good breaking capacity, small over-voltage, long electrical life and maintenance-free arc extinguish chamber. -Advanced GSC series (SIC and SQC type) indoor SF6 load break switch and composite apparatus are adopted. It has three positions:"closed", "open", "earthed".
