SYG-ZQ-150 Bimetallic Compression Connector is suitable for connecting LGJ-150/8 and LGJ-150/20 overhead aluminum conductors to copper terminals in high-voltage transmission and substation systems.

The connector adopts an aluminum base with a thin copper cladding layer formed through our proprietary brazing-clad copper-aluminum metallurgical composite process. The copper-aluminum transition area is fully metallurgically bonded, without a traditional weld seam, providing stable conductivity and improved resistance to heat generation, power loss and electrochemical corrosion.

Compared with conventional brazed products, key electrical performance indicators can be improved by up to 30–40%, depending on test conditions.
