FAQs
Q: Is the SC150-6 lug compatible with both 250 MCM and 300 MCM conductors?
A: Yes. The SC150 series is specifically designed to accommodate the cross-sectional area of 150mm², which bridges the gap between 250 MCM and 300 MCM standards depending on the strand count and cable type. Its 16.5mm inner diameter ensures a secure fit for these high-capacity conductors.
Q: What makes XLUIG SC terminals suitable for high-voltage power distribution?
A: Our SC terminals are manufactured from seamless T2 electrolytic copper. Unlike folded or welded lugs, the seamless tube design can withstand higher mechanical stress and electrical loads without risk of failure, making it the preferred choice for 35KV systems and heavy industrial grids.
Q: Why use electro-tin plating for these large-gauge terminals?
A: For large conductors like 150mm², maintaining low contact resistance is critical. Our industrial-grade tin plating prevents copper oxidation and galvanic corrosion, ensuring that the connection remains efficient and safe throughout its entire service life.
