Good quality starts from the source. Excellent material has the characteristics of low resistance and small temperature rise. It has a long service life and is not easy to oxidize. ; Flexible and convenient installation, suitable for continuous connection of bundled cables, insulated single-core conductors, naked conductor stranded cables, and mostly used for non-load-bearing connection and branching of conductors in overhead power lines. Anti-pollution, hydrophobicity and aging resistance, stable performance in cold, humid, dirty and other environments; stable performance, strong resistance, electricity resistance, compression resistance, corrosion resistance, stable performance and long life, the same life as the cable body.
