ZF 550kV Gas Insulated Switchgear

Model NO.
ZF-550
ZF-330,550 GIS 550kV gas insulated switchgear is a new kind of super -voltage and high-capacity SF6 gas-insulated metal-enclosed switchgear by Leistung Energie, digesting and absorbing GIS product of super-voltage technology from home and abroad, and combining many years of researching & developing experience and the latest research results. The super -voltage GIS switchgear abides by the requirements of GB7674-2008, IEC60517-1990, and tendering technical data of the state grid.
Quantity:
Structure and Features:▪The GIS features a new compact design. The minimum width of the bay is 2.1m and the technology incorporated is considered to be on the leading edge of the industry in China.▪The incorporated breaker is of self-energized style (pressure and thermal expansion) with a simple and reliable structure, strong breaking capability, short arcing time, long service time, 2 cycles of total breaking time and 20 times of breaking at full capacity.▪The breaker uses an ABB hydraulic spring mechanism with a simple and compact structure, high reliability, low maintenance, and long mechanical life up to 6000times.▪The enclosure of the GIS is made of an aluminum alloy that offers corrosion resistance, eliminates losses due to eddy current, is thermally insulated, and its light weight puts less pressure on the foundation..▪The radio interference level is lower than 500μV, which ensures the GIS can be installed in urban districts and residential areas.▪The GIS can be operated in the toughest environmental conditions,such as heavy pollution,frequent hails,high altitudes,frequent earthquakes,hard to dig mountainous terrain and crowded urban districts with limited space.▪The GIS is highly flexible.It can be assembled with multiple styles of connections,such as single bus bar section,bridge connection,double bus bars etc,according to the users' requirements.▪The SF6 gas-insulated switchgear can be delivered completely assembled except the outgoing bushing and partial connecting bus bar, allowing for fast and easy on-site installation.▪The new compact GIS switchgear can be installed indoors or outdoors.
