Low Voltage, Medium Voltage input switchgear cabinet

Low voltage, medium voltage switchgear cabinet - Medium voltage switchgear cabinet: Manufactured into separate functional cavities (switchgear cavity, cable cavity, busbar cavity and low voltage cavity) to avoid transmission problems. Even in an air-insulated environment, the entire busbar is insulated to increase its safety. The Vacuum Circuit Breaker (VCB) ensures maximum safety when servicing and replacing

Low voltage, medium voltage input switchgear cabinet

Introduction of low-voltage switchgear cabinet (general input cabinet):

Medium and low voltage input switchgear cabinet as well as general input cabinet composed of ACB air switchgear, MCCB switchgear equipment mounted on sturdy steel cabinet frames and connected by conductive busbar copper system, ensuring electrical insulation. The cabinet is installed after the transformer and near the additional load to control and distribute voltage to additional load. Some of the features of these low voltage cabinets are the separate measuring compartment for the management of power companies or the current transformers for measuring circuits and counted separately from the switchgear compartment.

Specifications:                              

  • Standard applicable: IEC439-1
  • Rated operating voltage: 400VAC, 50Hz
  • Rated current: up to 6300A
  • Protection level: IP54outdoor cabinet, IP42indoor cabinet.
  • Main equipment: ACB, MCCB Air switchgears.
  • Cabinet frame: Steel, 1.5-2.5mm thick.

Low voltage, medium voltage switchgear cabinet – Medium voltage switchgear cabinet:

Manufactured into separate functional cavities (switchgear cavity, cable cavity, busbar cavity and low voltage cavity) to avoid transmission problems. Even in an air-insulated environment, the entire busbar is insulated to increase its safety. The Vacuum Circuit Breaker (VCB) ensures maximum safety when servicing and replacing. Moreover, the dynamic cavities are equipped with pressure relief valves to keep the operator’s safety.

Application: Equipped for heavy industry factories such as paper, cement, iron-steel, industrial parks and EVN power stations.
