Product Details
SYG-ZQ-240 Bimetallic Compression Connector is designed for connecting LGJ-240/30 and LGJ-240/40 overhead aluminum conductors to copper equipment terminals in high-voltage transmission and substation systems.
It is manufactured with an aluminum base and a thin copper cladding layer using our proprietary brazing-clad copper-aluminum metallurgical composite process. The copper-aluminum interface achieves 100% metallurgical bonding without a traditional weld seam, helping reduce contact resistance, temperature rise, electrical 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.
