Import Bi-Metal Lug — Buy in wholesale FOB from Supplier in China

Jiangsu Sanqi Cable & Wire Co., Ltd., located in Rudong Economic Development Area, Jiangsu Province, produces bi-metal lugs for connecting aluminium conductors to copper terminals in power distribution systems. The lug construction uses an aluminium barrel with minimum 99.5 percent aluminium purity and an electrolytic copper palm with minimum 99.9 percent copper purity. This material pairing addresses galvanic corrosion between dissimilar metals in electrical joints. The supplier states compliance with IEC 61238, the international standard for mechanical and compression connectors.

The aluminium barrel is friction-welded or explosion-welded to the copper palm, creating a metallurgical bond without intermediate plating that would degrade over time. Barrel dimensions vary with conductor cross-section, typically from 16 mm2 to 400 mm2 in standard power distribution ranges. The copper palm is drilled with standard bolt holes, commonly M8 to M16, to match switchgear and transformer terminal spacing. Surface treatment typically includes tin plating on the copper palm and either tin plating or chromate conversion on the aluminium barrel to reduce oxidation resistance.

These bi-metal lugs suit utilities, renewable energy installers, and industrial electricians terminating aluminium cables onto copper busbars or equipment terminals. Applications include switchgear connections, transformer terminations, and solar PV array string combiners where aluminium conductor cost advantages apply. Importers should confirm the specific conductor range, palm hole configuration, and whether the lugs are supplied as standard barrel type or with oil-stopping barriers for oil-filled transformer applications. Jiangsu Sanqi's location in Rudong, near Nantong port, offers export logistics advantages for containerised shipment.
