KYN1-40.5(Z) Armored Removable AC Metal-Clad Switchgear Product Introduction
1. Product Brief Introduction
The KYN1-40.5(Z) type armored removable AC metal-clad switchgear (hereinafter referred to as switchgear) is an indoor switchgear assembly with three-phase AC 50Hz and rated voltage of 40.5kV. It is used for receiving and distributing electric energy in power plants and industrial and mining enterprises, and plays the roles of control, protection and monitoring of power circuits. It can also be used in places requiring frequent operation.
The switchgear complies with the standards of GB/T11022-1999, GB3906-1991 and DL404-1997.
