Busbars

Definition: Busbars are metallic strips or bars used to conduct electricity within a switchboard, distribution board, or other electrical apparatus.

Common Materials: Copper, Aluminum, or Silver.

Applications: Power distribution in substations, switchgear, battery systems, and high-current applications.

Key Features:

• High current capacity
• Low resistance
• Mechanical rigidity
• Heat dissipation capability

Types:

1. Rigid Busbars
2. Flexible Busbars (e.g., braided straps)
3. Insulated vs. Bare

Design Considerations: Current rating, thermal expansion, short-circuit withstand, corrosion protection, and insulation clearance.
