General:
KYN 61-40.5 Indoor Metal-clad AC Switchgear (hereafter referred to as Switchgear) is a new generation of indoor
complete set of switchgear, conformed to GB 3906 [3-35KV Metal-clad Switchgear]. It is assembled by bent zinc
plates coated with aluminum by imported and is designed beautifully. The main switch adopts circuit-breaker
made by Powell Co. Of USA, according to Chinese Standards. It is the most popular middle mounted switchgear
among the users.
It is used to single bus section system of three-phase AC with 35KV rated voltage and 50Hz rated frequency to
accept and distribute electric power. It is indoor switchgear which can control, protect and monitor the circuit.
Product feature:
A. Metal-clad structure;
B. It is assembled by imported multiple bent zinc plates coated with aluminum and rivets;
C. Original vacuum circuit breaker trolley;
D. Original cap shaped and longitudinal magnetic field vacuum ceramics extinction arc room with low cut value;
E. Off and on spring operating mechanism of low vibration and low noisy obtained a patent from America;
F. The front and back layout of the mechanism and the switchgear is easy to be debugged;
G. The busbar is covered by pyrocondensation insulating material;
H. The simulation busbar board adopts a new type dynamic indicator;
I. The earthing switch has high making ability and is operated by bevel gear mechanism, the operating force is
small;
J. The structure of middle mounted trolley with good interchangeability and mechanical stability;
K. Dimension (width*depth*height): 1200x2500x2300 (dwindling 30% in size than the similar product).
Ordering notice:
