A bus duct up to 6300A is an enclosed, pre-fabricated system using copper or aluminum bars (busbars) within a metal casing (enclosure) to efficiently distribute high electrical currents ( 6300A) in large buildings or industries, offering space savings, superior safety, better heat dissipation, and easier installation than heavy power cables, ideal for power distribution from switchgear to heavy loads in malls, data centers, and factories. 

High Capacity: Handles substantial current (up to 6300A) for heavy-duty applications.

Materials: Conductors are copper or aluminum; enclosures are typically CR steel or aluminum.

Construction: Sandwich design with epoxy/mylar insulation for high dielectric strength, enclosed for safety and protection.

Efficiency: Reduces voltage drop and reactive power compared to cables.

Components: Straight sections, elbows (for turns), tap-off boxes (for connecting loads), and supports.

Variants: Available as air-insulated (Al/Cu) or sandwiched (SMC/DMC/FRP insulated). 

Industrial Plants: Powering heavy machinery.

Commercial Buildings: Distributing power for HVAC, lighting.

Data Centers: Efficient server power management.

Power Distribution Rooms: From transformers to switchgear. 

Compact & Space-Saving: More compact than traditional cable systems.

Safe & Reliable: Fully enclosed, high short-circuit withstand.

Easy Installation: Faster and simpler to install on-site.

Better Performance: Superior heat dissipation and lower power loss.
