Product Description

22kv Medium Voltage Rmu Air Insulated Switchgear

Product Description
Combining with advanced technology both at home and abroad, we developed GSM series indoorair insulated (modular SF6) switchgear (hereinafter referred to as switchgear) and GSC series (SIC and SQC type) indoor SF6 load break switch and  composite apparatus.  
 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".
