Gustav Klauke 107R8 70 mm² Electro-Tinned Copper Press Cable Lug

Terminating 70 mm² copper cables can be a challenge: the connection must handle high current without overheating, resist corrosion, and stay mechanically secure for years. The Gustav Klauke 107R8 press cable lug solves this with a precision-machined electrolytic copper body and an electro-tinned finish that prevents oxidation and keeps contact resistance low over time. The inspection hole lets you verify correct crimp position instantly, so you can work with confidence in critical power installations.

Who is it for

Electricians and panel builders who need to attach ring lugs to M8 studs in control cabinets, switchgear, busbars, machine wiring, and power distribution units. Its compatibility with stranded and fine-stranded conductors makes it a versatile choice for both flexible and rigid cables in real-world wiring.

Main features

• High-conductivity electrolytic copper (E-Cu) for continuous high-current flow
• Electro-tinned surface protects against galvanic corrosion and reduces contact resistance drift

Tips

Use the correct hexagonal crimping die for 70 mm² conductors and a crimping force of 6-10 tons. Always slide the lug fully onto the stripped conductor until it reaches the inspection hole, then crimp. For best corrosion protection in harsh environments, consider using heat-shrink tubing over the crimp area. Verify that the bolt hole aligns properly with the M8 stud before tightening.
