Product Description
Product Description1.IntroductionKYN61-40.5 armored type movable AC metal-enclosed switchgear is used for three-phase AC 50Hz and 40.5kV single busbar and single busbar sectional system. It is mainly used for control, protection and monitoring in different fields, such as for power transmission and distribution in power plants, electric power substations, industrial and mining enterprises and high buildings. It meets the requirements specified in standards IEC60298, GB3906 and DL404. It has complete "five-prevention" function.2.Features
1)Heat-shrinkable insulation or epoxy coat is used as insulation to optimize shape of the electrode.
2)The switchgear uses imported hot-dip Al-Zn plates processed and formed by CNC machining tool, connected together by high strength bolt nut and rivet nuts.
3)It can be equipped with home-made or imported vacuum circuit breakers meeting needs of different users;
4)All functional cubicles are separated by metal plates fitted with independent pressure release channel.
5)Roll ball lead screw propulsion mechanism is used to make easy movement of the truck.
6)Switchgear structure has strong adaptability.
7)Mechanical interlocking mechanism for avoidance of misoperation
8)Easy operation and maintenance.3.Main Technical Data| S/N | Item | Unit | Data |
