KXHXGN-12 type AIS Switchgear produced by KEXR, a power transmission and distribution equipment supplier in China, is a 12kV gas-insulated ring network cabinet (C-GIS) with environmental protection gas (such as dry air, nitrogen or mixed gas) as insulation medium, which is suitable for ring network power supply, terminal power supply and small-scale opening and closing stations of distribution networks.
● Main feature of AIS Switchgear
(1) Environmental protection advantages
◆Free SFgas: AIS Switchgear adopts dry air, nitrogen or new environmental protection gas (such as G, AirPlus®, etc.) are used, which is in line with EU F-Gas regulations and China's "double carbon" policy.
◆Low carbon emission: Compared with SF ring network cabinet, GWP (Global Warming Potential) approaches zero.
(2) Structural design
◆Modular design: The AIS Switchgear unit of incoming line, outgoing line, metering and PT can be expanded.
◆Enclosed structure: The protection level of AIS Switchgear reaches IP67, which is dustproof, moisture-proof and condensation-proof, suitable for harsh environment.
◆Compact size: it saves space than AIS ring network cabinet and is more environmentally friendly than traditional SF₆ GIS.
(3) Intelligent options
Intelligent monitoring (such as DTU, online temperature measurement, partial discharge monitoring, etc.) can be selected to support Internet of Things (IoT) access and realize remote operation and maintenance.
