350 kcmil Aluminum Crimping Die
The Burndy U31ART is a single-piece Type U crimping die set designed for 350 kcmil aluminum lugs. It carries a brown colour code and is rated for a maximum crimping force of 12 ton. The die is intended for electricians and line workers terminating large aluminum conductors with compatible compression connectors.
Compatible Tooling and Series
Verify that your crimping tool accepts U-style upper and lower dies and delivers up to 12 ton of force. This die fits Burndy tools including the PAT46, PAT750, PUADP1, Y35, Y46 and Y750, covering the 35 Series and 750 Series platforms. Confirm your tool model before ordering to ensure correct die seating and compression performance.
Upgrade From Smaller Dies
This die replaces smaller-capacity U dies when moving to 350 kcmil aluminum lugs and YA-A or YS-A connector types. The jump is justified when project specifications call for the brown colour code and 12 ton compression on this conductor size. It is not suited for copper lugs, other cable sizes or tools outside the listed series.
