Air-Insulated Busway — Air Type Bus Duct
Air-insulated (air-type) busway uses busbars separated by air gaps within a ventilated or non-ventilated enclosure, providing high short-circuit withstand and ease of inspection. Rated 250–6300 A, 380/400/690V, suitable for industrial power distribution where ventilation and simple maintenance are preferred over compact dense construction.
Applications
Industrial power distribution
Manufacturing plants
Commercial risers and feeders

Withstand
Verify short-circuit withstand rating matches the upstream fault level.
Sections
Plan straight, elbow and tee sections for the route.
- Frequently Asked Questions
What is air-insulated busway?
Air-insulated busway separates busbars with air gaps inside a ventilated enclosure, allowing inspection and providing high short-circuit withstand, at the cost of a larger footprint than dense busway.
When is air-type preferred?
For industrial plants where inspection access and short-circuit withstand matter more than compactness.
Ventilated or non-ventilated?
Non-ventilated (IP54+) for dusty/humid environments; ventilated for lower cost indoor applications.
