KYN61-40.5 High voltage AC metal enclosed switchgear customized by professional switchgear manufacturer
Product description
KYN61-40.5 armored removable AC metal-enclosed switchgear
(hereinafter referred to as switchgear) three-phase AC 50Hz, rated
voltage 40.5kV indoor complete power distribution device. As power
plants, substations, and industrial and mining enterprises to
receive and distribute electric energy, it can control, protect and
monitor circuits, and can also be used in places with frequent
operations.
This switchgear complies with GB3906-2006 "3~35kV AC Metal-enclosed
Switchgear", GB/T11022-1999 "High Voltage Switchgear and Control
Equipment Standard Common Technical Requirements" and DL/T 404-2007
"3.6kV~40.5kV AC Metal-enclosed switchgear and control equipment"
and other standards.
