40.5kV AC Meta l- Clad Safety Electrical High Voltage Switchgear With Stainless Steel
Product Introduction:
KYT1 (KYN61)-40.5 Metal-clad Drawable AC Switchgear is a three-phase AC 50Hz, indoor whole set distribution unit with rated voltage 40.5kV, which is used to accept and distribute electric energy in power plant ,substation and industrial and mining enterprises. It can control, protect and supervise circuits, and be used in the place need to operate frequently.
Features:
a. Cubicle structure is an assembly type, circuit breaker adopts handcart floor type structure.
b. It matches with new type compound insulating vacuum circuit breaker, and has the advantages of good interchangeability and easy change.
c. Handcart is equipped with feed screw nut feed mechanism which makes movement of the handcart easy and prevent maloperation from damaging feed mechanism.
d. All operations will be done under the closed doors.
e. Interlockings of main switch, handcart, and between cubicles adopt coerciveness mechanical interlock, which meets the requirements of “five-prevention” function.
f. There is abundant space in cable room to connect many cables.
g. The enclosure is IP4X which will be changed to IP2X when doors of handcart are opened.
