AC Metal-clad Switchgear KYT1(KYN61)-40.5
KYT1(KYN61)- 40.5 AC Metal-clad Switchgear is an indoor complete set of switchgear of 50HZ three phase AC and 40.5 KV rated voltage. It is used for accepting and distributing electric power in places, such as power plant, substation and industrial and mining business. It can control, protect and test the circuit and also be used in places where it is busy for operating.
Product feature :
a. The body of the switchgear has package structure and the circuit breaker has truck falling type structure.
b. It is fitted with a new type compound and insulating vacuum circuit breaker. It is featured by good interchangeability and easy alternation.
c. There is a propelling mechanism of feed screw nut in the trolley shelf, which makes it easy to move the truck and can prevent incorrect operation from damaging the propelling plant.
d. All of the operation shall be in the condition of cubicle door closed.
e. The interlock among the main switch, trolley and the cubicle body is mandatory mechanical latching and has function of "Five protection".
f. There is enough space for cable room, so multi-cable can be connected.
g. The protection level of the enclosure is IP4X; when the door of the trolley room opens, the protection level is IP2X.
