Marine Power Distribution: The Role of Copper Bus Bar in Marine Vessels

Whether used for power generation, transportation, or logistics, marine bus bar plays a powerful role in ship power distribution.

Since most equipment, machines and systems used on ships operate electrically, the demand for superior marine power distribution remains a continual focus.

The type of marine bus bar needed is dependent on the type of vessel, required machinery and its electrical propulsion. Since the main switchboard is the primary power distribution system and center of the ship, the main bus bars are located in the lowest portion of this switchboard to ensure protective insulation and support.

Marine bus bar within the main switchboard serves multiple auxiliaries, such as voltmeters, watt meters, ammeters, etc.

Copper bus bar is most commonly used in marine power distribution due to:

  • Hardness
  • Lasting and Reliable Quality
  • Cost-Effectiveness
  • Resistance to Mechanical Damage and Corrosion
  • High Mechanical Strength in Compression, Shear and Tension
  • Good Conductivity with Terminals and Other Typically Copper Components

In marine applications, the primary disadvantage of copper bus bar over aluminum bus bar is density and weight. However, copper is still the preferred choice for marine applications.
