In line with the principle of mutual support of relative advantages and sharing economic resources, JIANGSU NANZI
TONGHUA ELECTRIC GROUP was recomposed of Nanjing General Automatic Equipment Factory, National Power
Company and original Jiangsu Tonghua Group in January,2003. NANZI TONGHUA ELECTRIC GROUP is a group company
specialized in producing and managing once-through-design equipment under NANZI set-up. Adopting the quintessence of
the first-class name-brand from NANZI's electric power system and inheriting all the resources of Tonghua Group it has been
an example of megamerger in electric trade.
The GROUP covers an area of near 200,000m2, has won the titles of the large-sized industrial enterprise in China, the
hi-tech one, civilian-run sci-tech one and contract-adiding by and trustworthy one in Jiangsu Province. It has also become a
key enterprise of power and electric-appliance industrialization base brought into line with the national Torch Plan. Among
the same trades in China it won the first batch of certificates of "the qualified enterprise in rectifying productive order for high
voltage switch cabinets" and "the qualified enterprise in rectifying the productive order and quality for low voltage, high rank
? ?
complete set of switch equipment (red certificate)" in 1995; was the first to win ISO9001 certificate issued by TUV
Identification Centre, Germany in 1996 and successfully carried out the identification in the correcting of 2000's edition in
2000; and successively won the "3C" compulsory identification symbols issued by CQC Institution for 14 lines of products in
2003; and the quality of all the products has been insured by PICC.
Jiangsu Nanzi Tonghua Electric Complete Set Co., Ltd. is an enterprise under the Group specialized in producing
complete set of electric equipment; and a strategic cooperative companion with SCHNEIDER, SIEMENS and ABB. The
Company has overall realized ERP management, has the modernized design means for products, advanced productive
technological facilities and testing equipment. It's specialized in producing 40.5kV and the below middle-low voltage

GCS低壓抽出式開關柜（Gas Insulated Combined Switchgear，簡稱GCS）是一種廣泛應用在工業、建筑、變電站等電力設施中的成套開關設備。它采用氣體絕緣技術，通常是SF6氣體，結合了斷路器、負荷開關、隔離開關、熔斷器以及測量儀表等多種功能元件于一個封閉的金屬殼體內，這些元件可以方便地按照工作要求單獨或組合抽出和推入，以實現電氣設備的安裝、操作、維護和檢修。 GCS開關柜具有體積小、重量輕、安全性高、占地面積少、操作簡便、維護周期長及運行噪音低等特點，特別適用于對電氣設備高度集成化、緊湊化有較高需求的場合，如電力系統的進線、饋出、母聯、分段以及重要負荷的配電與保護。同時，由于采用了氣體絕緣介質，其內部故障隔離性能優良，提高了供電系統的可靠性。
