Build scalable bus duct (busbar trunking) routes for industrial and commercial power distribution. Choose conductor material (copper / aluminum), select feeder or plug-in layout, then complete the run with joints, fittings, tap-off boxes, and support hardware—matched to your drawings and site conditions.
Start with your SLD and route plan, then confirm current rating, conductor choice, and plug-in needs. We’ll align section list, joint logic, and tap-off schedule to your installation method.
Copper or aluminum conductors for different loss, weight, and cost priorities.
Fixed feeder runs or plug-in sections for flexible, scalable power distribution.
Connection logic designed for consistent assembly and inspection on site.
Elbows, tees, offsets, risers, hangers, and accessories to complete the route.

Busway is built for predictable power routes—standard trunking sections + junction units + optional tap-off distribution. Compared with cable-heavy runs, it improves installation order, expansion flexibility, and project documentation clarity.
A busway route is assembled from standardized sections, keeping the current path short and structured. This simplifies layout planning for long corridors, equipment rooms, and multi-panel distribution areas.
Plug-in / tap-off points allow localized distribution without re-routing the whole trunk line. Add or relocate feed points as equipment changes—ideal for facilities that evolve over time.
Prefabricated sections reduce cable bundling and on-site improvisation. With defined joints, supports, and junction geometry, crews follow a cleaner installation sequence with less rework.
Select protection intent (e.g., indoor dust/moisture vs harsher areas) and lock it into the ordering code. The BOM becomes inspection-ready: section list, joint logic, tap-off schedule, and mounting hardware.

Busway (busbar trunking) is used where power routes must stay clean, expandable, and easy to maintain — especially in long corridors, technical spaces, and facilities with changing loads.
A structured busway route keeps long tunnel distribution predictable and serviceable for inspections and upgrades.
Busway supports expandable power distribution with clear routing and optional tap-off points for new racks and rooms.
Used between switchboards and load areas to keep feeder routes clean, documented, and easier to maintain than large cable bundles.
Ideal for production lines with changing layouts — add tap-off feeds without rebuilding the main trunk route.
For transit tunnels, defined trunk sections and joints make long-run distribution easier to plan, install, and service.
Suitable for large facilities where scalable distribution routes and maintenance access are critical across long corridors and zones.
Busway performance is decided by conductor preparation, insulation integrity, and joint consistency. We control the process to keep sections, joints, and tap-off interfaces installation-ready.
Select conductor material (Copper / Aluminum) and housing structure. Confirm rating intent and installation environment before section design is locked.
Apply insulation system and maintain clearance/creepage intent inside the enclosure so the trunking remains stable under load.
Build straight sections and standard parts with controlled alignment, so field installation stays predictable for long corridors.
Joint consistency is critical. We control contact interface condition and assembly repeatability to reduce site ambiguity.
Verify assembly integrity and section readiness prior to delivery so receiving and installation can follow a clear sequence.
Section labeling and packing logic help site teams stage trunking, elbows, and accessories efficiently—reducing rework on arrival.
Share your SLD and route plan (length / elbows / risers), current rating and installation environment. We’ll help validate the section schedule, tap-off plan, and deliver a project-ready BOM for fast quotation and site-ready installation.
