The HXGN17 series box-type fixed metal-enclosed switchgear represents a significant advancement in high voltage power distribution systems. It has been completely redesigned with a focus on enhancing insulation and protection levels compared to traditional handcart switchgear and GG-1 (A) F type switchgear. Noteworthy improvements include achieving higher insulation and protection levels without the use of interphase structures, relative clapboards, or insulation gases in the internal components. The secondary circuit has been streamlined, eliminating the need for secondary plugs.
Designed for application in 7.240.5kV electric power distribution systems, this switchgear plays a crucial role in the acceptance and distribution of high voltage power equipment. Emphasizing safety, it complies with the "five prevention" requirements and meets the IEC298 standards for "340.5kV AC metal closed switch." Additionally, it aligns with internationally recognized benchmarks such as IEC62271-200 and IEC62271-100, ensuring its reliability and adherence to global standards.
