Busbar

  A busbar is a conductive strip or bar, typically made of copper, brass, or aluminum, used to distribute electrical power in a variety of systems, including power distribution panels, substations, switchgear, and electrical circuits. Busbars are designed to carry large currents and serve as a centralized hub where multiple electrical connections can be made efficiently.

1. Current Carrying Capacity (Ampacity)

   Factors Influencing：

     - Material (Copper or Aluminum)

     - Cross-sectional area

   Typical Values:

     - Copper: ~1,000 A for a 10 mm² cross-section

     - Aluminum: ~640 A for a 10 mm² cross-section

2. Voltage Rating

    Insulation: Higher voltage ratings require adequate insulation and creepage distance.

   Common Values: Can range from low-voltage systems (up to 1 kV) to medium- (1 kV–36 kV) and high-voltage applications (36 kV+).

 3. Resistance

   Typical Resistance Values: Very low, e.g., for copper, ~0.0175 µΩ·m at 20°C.
