Busbars

Efficient Electrical Conduction

Busbars

A Busbar, also known as a copper bus or copper busbar, is a lengthy conductor made of copper with a rectangular or chamfered (rounded) rectangular cross-section. In modern applications, rounded copper bars are preferred to prevent sharp discharges.

Types of Busbars:

Busbars are classified into soft busbars and hard busbars (wires). Soft and hard busbars are complementary concepts, both serving as conductive components in the electrical industry, particularly in high-current applications.

Design Considerations:

The design of a busbar requires careful consideration of its current-carrying capacity. The selection of an appropriate busbar is generally based on the magnitude of the current it will carry. Proper tightening of screws at busbar connections is crucial to avoid overheating and melting caused by high currents.

Applications:

Conductive Material:
- Widely used in various applications, including new energy vehicle batteries, energy storage batteries, distribution equipment, high and low voltage electrical appliances, aviation electrical systems, and large-current electrolytic smelting projects.
Current Transmission and Electrical Equipment Connection:
- Applied in high and low voltage electrical appliances, switch contacts, distribution equipment, and other large-current conduction fields. Its primary function is to transmit current and connect electrical equipment.
Primary Circuit Applications:
- Busbars come in bare copper and tin-plated copper variants. In cabinet applications, busbar connections typically undergo tin plating, embossing, or the addition of conductive paste. Protective measures such as heat-shrink tubing or insulating varnish are applied to spare areas.
