A cable lug is the crimped or bolted metal fitting that terminates a power cable and bolts it to equipment. This engineer's guide covers the three lug metallurgies (copper, aluminum, bimetal Cu-Al), the governing standards (DIN 46235, IEC 61238-1, GB/T 14315), conductor sizing from 10 mm² to 630 mm², crimping best practice, and how to avoid the copper-aluminum galvanic corrosion trap. Drawn from 20+ years of manufacturing experience at MINGXU, an ISO 9001 / 14001 / 45001-certified supplier used in State Grid UHV projects and export markets worldwide.
Prevent network downtime and reduce costs with durable aerial cable accessories. Get outdoor clamps and tension clamps built for extreme weather.
Stop overhead line failures: specify insulation piercing clamps for moisture sealing, torque control, and EN 50483 compliance. Ensure reliability.
