MV Switchboards

Medium voltage switchboards are integral components of electrical distribution systems designed to handle higher voltage levels typically ranging from 1 kV to 36 kV. These switchboards serve as central enclosures for housing and protecting medium voltage switchgear, control gear, and associated equipment. They play a crucial role in the safe and efficient distribution of electricity in industrial plants, commercial buildings, substations, and utility networks.

Main Components:

  • Main Incoming Devices: These devices, such as vacuum circuit breakers or load break switches, connect the switchboard to the medium voltage power source.
  • Distribution Switchgear: Medium voltage switchboards feature switchgear components specifically designed to handle medium voltage levels. This includes vacuum circuit breakers, air-insulated switchgear (AIS), gas-insulated switchgear (GIS), or load break switches.
  • Busbars: Busbars provide a conductive path for the distribution of electrical power within the switchboard. They connect the incoming devices to the distribution switchgear and other components.
  • Protection and Monitoring Devices: Medium voltage switchboards incorporate various protective devices, such as overcurrent relays, earth fault relays, and voltage protection devices, to safeguard the switchboard and connected equipment against electrical faults. Monitoring devices provide essential information about voltage, current, and power parameters.
  • Control Gear: Control gear components, such as contactors, relays, and timers, facilitate the control and automation of medium voltage circuits within the switchboard.
  • Enclosures and Protection: Medium voltage switchboards are housed in robust enclosures constructed from materials such as metal or reinforced plastic to provide protection against environmental factors, such as moisture, dust, and mechanical damage. Adequate ventilation and insulation are also essential to ensure safe operation.
