GCS type low-voltage withdrawable switchgear

• Compact structure: smaller space accommodates more functional units Strong universality of components and flexible assembly.

• Adopting standard module design: There are five size series standard units, and users can choose and assemble them according to their need .

• High technical performance: The rated short-time withstand current of the MCC cabinet's vertical busbar is 80kA, and the horizontal busbar adopts a counter mounted layout, which can withstand a peak withstand current of 176kA, reaching the contemporary international level..

• The separation between functional units and compartments is clear, reliable, and does not affect the operation of other units due to the failure of one unit, so that the local fault is minimized.

Product Introduction

GCS type low-voltage withdrawable switchgear is a complete set of equipment used for energy distribution, control, and protection in power systems, widely used in power plants, substations, industrial and mining enterprises, high-rise buildings, commercial centers, and other places. It is suitable for distribution systems with AC 50Hz or 60Hz, rated working voltage of 660V and below, and rated current of 6300A and below, mainly used for energy distribution, control, and protection.
