Product Overview
Mechanical Bimetal Lug
The JTLL series mechanical bimetal lug is engineered for the transition connection of aluminum or aluminum alloy cables to copper terminals in low-voltage electrical equipment. Featuring a high-strength aluminum alloy body and friction-welded construction, these lugs ensure stable performance and prevent galvanic corrosion. Designed for ease of use, they eliminate the need for specialized crimping tools, requiring only a standard wrench for installation.
