Bi-Metal Lugs: Aluminium-to-Copper Cable Terminations for Electrical Contractors
When a cable termination needs to join an aluminium conductor to a copper connection point, the lug design and conductor fit matter. SCHNAP’s bi-metal lugs range includes through, cable, stalk, sector, ABC and crimp formats for electricians and contractors working on electrical distribution and switchboard connections. For jobs where an insulated style is specified, review the Repelec 150mm² M12 bi-metal pre-insulated lug against the project requirements before ordering.
What's in This Range
- Pulset 16mm bi-metal through lug — a through-lug option listed for 16mm wire size and crimping.
- Repelec 120mm² M12 bi-metal cable lug — combines a listed conductor size with an M12 connection point.
- Cabac 95mm² bi-metal stalk lug — features a friction-welded aluminium barrel and copper palm for aluminium-to-copper stud terminations.
- Cabac 185mm² four-core bi-metal sector lug — a sector-style termination option with an aluminium barrel and copper palm.
- Cabac 95mm² bi-metal ABC lug — designed for aluminium cable to copper stud connections as stated on the product page.
- Wattmaster 185mm² M10 bi-metal crimp lug — lists a 185mm² conductor size and M10 stud size, with compliance details on its product page.
- Cabac 800mm² bi-metal cable lug — a larger conductor-size option with a friction-welded aluminium barrel and copper palm.
- Repelec 240mm² M12 bi-metal cable lug — another conductor and stud-size combination for matching to the termination design.
Who Uses This
Licensed electricians and electrical contractors specify bi-metal lugs when a termination design calls for an aluminium conductor to connect with a copper palm or stud. These products may be considered for switchboard work, distribution equipment and larger cable termination projects. Confirm the actual cable construction, conductor size, connection hardware and installation design before selecting a part; the category name alone does not determine suitability.
Bi-Metal Lugs — Common Questions
What conductor size should I choose?
Start with the conductor size specified for the cable, then match it with the lug’s documented conductor range and connection arrangement. For example, the Pulset 50mm bi-metal through lug is listed for a 50mm size. Check the individual product details and the specified termination method before purchase.
When might a mechanical shear lug be suitable?
A mechanical shear-bolt design is an option to assess when the project specifies that termination method rather than a crimped connection. SCHNAP lists the Cabac 120–300mm² tinned bi-metal mechanical shear lug as rated up to 36kV and identifies IEC EN 61238-1-3 on its product page. Verify the part’s documented conductor range and system requirements for the actual installation.
What should I check before ordering bi-metal lugs?
Check the conductor material and size, lug connection style, stud or terminal dimensions, and the termination method required by the design. Review the product page for any stated material, compliance or installation information; do not assume that one lug suits every cable or terminal. Where details are missing, confirm compatibility with the manufacturer or project specification before installation.
Why Choose SCHNAP
