Power Distribution & Energy Integration: Copper Busbar Market Applications

  • Copper busbars are effective for the uninterrupted integration of renewable energy sources, such as solar and wind, into power grids. 
  • Beyond linking high-voltage equipment in electrical switchyards and low-voltage equipment in battery banks, copper busbars are important in the automotive and defense industries. 
  • Their application spans diverse environments, including factories, data centers, retail facilities, laboratories, and technology settings
  • Additionally, specific variants, like laminated busbars, are prevalent in cellular communication systems, telephone exchanges, military equipment, and power generation systems. 
  • Flexible busbars, on the other hand, find utility in electric, hybrid, and fuel cell vehicles, charging stations, switching cabinets, and power links for generators and transformers.

Extrusion & Rolling Phases in Copper Busbar Market 

The copper busbar production cycle comprises eminent steps aimed at efficient and energy-saving manufacturing, including these

  1. Initially, cathode copper undergoes melting in a preheated and dried melting device. The copper solution’s surface is coated with charcoal and graphite scales, and a copper rod is drawn through a tractor using a separation and reunion approach.
  2. In the subsequent phase, an oxygen-free copper rod, a byproduct of the initial process, serves as the raw material. It undergoes straightening on a dedicated device before entering a continuous extruding device for extrusion. The resulting blank is promptly cooled to 40–60°C post-extrusion at high temperatures.
  3. Following this, the cooled copper busbar blank is directly fed into two rolling mills for the rolling process. 
  4. Ultimately, a slitting tool is employed to cut the copper busbar. This production method distinguishes itself with its coordinated procedure, efficiency, and energy-saving attributes.
  5. Compared to conventional processes, it eliminates head and tail cutting in the drawing procedure, improves material utilization rates, reduces energy consumption by over 20%, and achieves a rolling yield of 90% or more.

Operational Resilience & Heat Management with Copper Busbar Types

Flat Busbars: These are widely recognized for their excellent current-carrying capacity and ease of fabrication. Available in a range of widths and thicknesses, they can be selected based on the desired current rating.

Round Busbars: Round busbars, with their increased surface area and enhanced heat dissipation capabilities, are ideal for high-current applications. Additionally, they exhibit greater mechanical robustness compared to flat bars.

Hollow Busbars: Similar to round busbars, those with a hollow core offer a reduction in weight without sacrificing strength or current-carrying capacity.

Shaped Busbars: Custom-designed for specific applications, these busbars feature distinct shapes. Examples include rectangular variants with rounded corners for enhanced current distribution and complex profiles made to seamlessly integrate with specific equipment.

In line with this, various manufacturers in the copper busbar market, including ABB Ltd, Aurubis AG, Eaton Corporation Plc, Rittal, and Luvata, produce and offer a variety of busbar types, including flat busbars, round busbars, hollow busbars, and custom-shaped busbars.

Functional Aspects and Electrical Role of Copper Busbar Market

Functionally, busbars serve as conductive components, typically appearing as single or multiple copper bars, whether exposed or enclosed. These systems incorporate joints to achieve the required length and configuration, featuring multiple take-off points connected to designated equipment. 

Further, electrically, copper busbars function as conductors or groups of conductors that gather electric power from incoming feeders and distribute it to outgoing feeders. Essentially, they serve as electrical junctions where all incoming and outgoing electrical currents converge. 

Moreover, the busbar system, equipped with isolators and circuit breakers, ensures safety during faults. In the event of a short circuit, the circuit breaker promptly activates, disconnecting the faulty section of the busbar from the circuit.
