GTL Series Copper-Aluminium Connecting Tube
YOCL ELECTRIC GTL Series Copper-Aluminium Connecting Tube joins a copper conductor to an aluminium conductor end to end. The series includes 15 models, GTL-10 through GTL-630, with separate dimensions for the two conductor entries.
- Copper and aluminium ends for a dissimilar-conductor splice.
- Compare D, d, D1, D2, L, L1 and L2 for every model.
- Specify the GTL model and quantity when requesting a quotation.
Overview
YOCL ELECTRIC GTL Series Copper-Aluminium Connecting Tube joins a copper conductor to an aluminium conductor end to end. The copper and aluminium sections form a transition tube with separate conductor-entry dimensions. The series covers 15 models, from GTL-10 to GTL-630.
Features
- Copper-to-aluminium connection: intended for a splice between dissimilar conductor materials.
- Separate entry sizes: D and d identify the aluminium side, while D1 and D2 identify the copper side in the source drawing.
- Model-specific lengths: overall length L and side lengths L1 and L2 are listed for all 15 models.

Selection Guide
Select the GTL model by the fit of both conductor entries: copper-side D2 and aluminium-side d. Check their outer diameters D1 and D, the overall length L and the corresponding side lengths L2 and L1 against the splice space. GTL-10 and GTL-16 share the same listed dimensions, so include the exact model designation in the enquiry.
Ứng dụng
For end-to-end copper-to-aluminium conductor splices in power distribution wiring where the selected tube dimensions suit both conductors.
