SF6 Insulated Switchgear

Service ambient conditions:
????? a. Air temperature: Max: +40C, Min: -25 C(average value<=? 35 C within 24 hours)
????? b. Altitude: <= 3000m (if exceed 3000m,please negotiate with the manufacturer)
????? c. Air humidity: Daily average relative humidity <= 95%, monthly average relative humidity <= 90%;
????? d. The range of induction electromagnetic interference in secondary system <=1.6kV

Product feature:
?????? a. Structure:
????? The compartments of GIS use 3-5mm corrosion resistance plates, which are firstly processed by digit-controlled lathe and then welded by welding robot, with the advantage of less amount of deformation, good seal. Other compartments are made of high quality cold rolled sheets, which firstly bent and then welded, with the characteristics of high accuracy and intensity. The functional units are separate module, so it is convenient for assembly. Besides the sealed compartments in the GIS have separate pressure release passages, which ensure the safety of the personnel and equipments.
????? b. Standards:
??????The universal technical requirements of GB11022-1999 HV Switchgear and control equipment standards GB/3906-1991 3-35 kV AC Metal-clad Switchgear
????? c. Protection degree:
????? IP 67 of gas insulating compartments, IP4X of LV switchgear
