KYN61-40.5-Z armoured transfer type AC metal closed switchgear is a complete set of electric power distribution system with rated voltage of 40.5kV and rated frequency 50HZ. As power plants, substations and industrial and mining enterprises to accept and distribute the three-phase power of 50Hz and 35kV power grid, the functions of control, protection and detection of the circuit are used.
This switchgear meets the standard of GB3906 and IEC298 (1009).
◇main features：
●
The switch cabinet has a smooth, simple and beautiful appearance, and has a simple and reliable "five defense" chain function to prevent misoperation.
●
The two line grooves in high pressure indoor use all metal protection, and the operation is safer and more reliable.
●
All devices are properly equipped with the same place for inspection.
●
When a substation is designed to form a complete set of equipment with various functions, it needs less space and can be applied to any premises inside and outside the house.
●
According to customer needs, it is easy to fit the structure, and easy to install and locate in any floor.
●
The charged part is properly insulated, and all the components are installed in the metal box, which is very safe for the personnel or equipment.
