Combined (Fixed) AC Metal-clad Switchgear XGN66A-12
XGN66A-12 Combined and Fixed Indoor AC Metal-clad switchgear is a new generation of HV electric whole set products£¬which is complied with national standard GB3906 [3-35kV AC Metal-clad Switchgear] and the specification of DL404 [Ordering technical condition of Indoor AC HV Switchgear] issued by Minister of Electricity Power as well as IEC 298 [From 1kV to 52 kV AC Metal-clad Switchgear and Control equipment] . And it has the closedown function of "Five production" put forward by Dept 2. This switchgear is suitable for three-phase AC 50HZ, 3-10kV single sectioning busbar system used to distribute electric power. It has the function of controlling, monitoring and protecting circuit. And it is wildly used in varieties of power plants, substation, industrial and mining enterprise and high rise buildings as well as combined with RMU to be applied in the switching stations.
Product feature :
a. Fitted in integer type vacuum circuit breaker, such as 12kV 3150A and 40kA;
b. A kind of specified designed switchgear in order to reduce occupied area of substation;
c. May combined with RMU randomly;
d. Simple but reliable machinery interlock for false protecting operation and easy operation;
e. The functional units are separated and fitted in separate pressure release passage to protect the malfunction from enlarging and expanding;
f. Isolating distance and cable terminal contacts can be watched through the view window.
