Medium Voltage Switchgear
KYN61-40.5 Metalclad AC Enclosed Switchgear, Withdrawable Type

KYN61-40.5 Air insulated metal clad movable switchgear is an indoor switchgear,assembly operating under the conditions of 50/60Hz three phase and rated 40.5kV AC voltage,which is applied to the transmission and distribution for generators,transformer substations and the industry and mine enterprises. It also can be used to control,protect and monitor electric circuits,and very useful for frequent operating conditions.
Standard: IEC62271-200

Selection

Operating conditions

1.Ambient air temperature: -15℃ ~+40℃
2.Altitude: ≤1000m
3.Relative humidity : Daily average≤95%; Monthly average≤90% 4. Earthquake 4.intensity:≤magnitude 8.
5.Applicable in the places without corrosive and flammable gas.
Note: Customized products are available.

Features

1.The cabinet is made of aluminum-zinc coated sheet processed by CNC equipment and assembled with bolts or rivets, with a fully modular structure.
2.This switchgear has various functions to prevent misoperations, including preventing loaded trolleys from moving, preventing live coupling and earthing switches, and preventing inadvertent entry into live compartments.
3.The switchgear is equipped with a ZN85 vacuum circuit breaker with excellent performance and a handcart, and the main busbar is connected without the need for transitional transfer.
4.This switchgear is an advanced, stable performance, reasonable structure, easy-to-
use, safe and reliable power distribution equipment
