Flat Palm Bimetal Cable Lugs — DTL-2F Series

DTL-2F flat-palm bimetal cable lugs for aluminium cable to copper busbar/stud.
Cu palm + Al barrel friction-welded for low resistance & anti-galvanic corrosion.
Flat palm profile for compact installs and large contact area.
Complete Φ / D / d / L / L1 size matrix from 16–630 for quick die/bolt selection.

Overview — DTL-2F flat palm bimetal lug

The DTL-2F Series are flat palm bimetal lug (Cu–Al) designed to connect
aluminium conductors to copper busbars or studs. The aluminium barrel (L3) is
friction-welded to a copper palm (T2), ensuring excellent electrical performance, strong mechanical integrity and
resistance to galvanic corrosion. The flat palm profile provides a larger contact area with a low
overall height—ideal for compact panels, MCCs and switchgear.

Installation Notes

Prepare aluminium strands (brush & apply oxide-inhibiting compound) before insertion.
Crimp along the barrel with the specified hex/compression dies to rated pull-out.
Mount to the copper bus/stud with the specified Φ hole size and the correct torque.
Seal the joint (heat-shrink/insulation) to meet the site’s environmental class.
