GCS With Drawable Low-voltage Switch Cabinet
-
Overview of the products
GCS device is suitable for distribution systems in these industries such as power plants, petroleum, chemical, metallurgical, textile,
and high buildings and, in such places as requiring high automation levels and computer interfaces, like large power plants and
petrochemical systems, can be used as a low-voltage complete distribution equipment for centralized control of distribution and
electric motors and reactive power compensation in the power generation and supply systems with a three-phase AC frequency of
50 (60) H, rated working voltage of 380V (400V), (660V), and rated current of 4000A and below.
