He's been using these SC series lugs for about six months now, and teh matte tin plating holds up noticeably better than the shiny stuff—especially in humid conditions, which is basically what they're for.
They fit both AC and DC hookups without any hassle, most of the guys on site prefer the round shape for tighter bends in panel work, and the cold pressing keeps the copper grain consistent even on the 630mm² ones.
Tempearture resistnce is solid enough for substation gear, though we've found they're not ideal for continuous exposure above 120°C or so without checking specs first, and you'll want the M25 screw option for the larger cable terminations.
What it does is cut down on rework—we'd usually have 10-15% failure with other brands on the 50mm² size, but these have been under 3% across the board, and the ISO 9001 cert backs that up.
Minimum order isn't an issue since there's no limit, which is pretty much unheard of for a shop that needs just 50 units of the 1.5mm² size for a pilot run (usually 2-4 weeks lead time, but confirm stock first).
The matte tin layer gives you solid corrosion resistance, especially in humid or outdoor setups, and it also makes soldering easier if you ever need to. Bare copper would oxidize faster, so this adds longevity without sacrificing conductivity.
Yes, samples are available — just reach out with your preferred size and quantity. We usually provide samples at a nominal cost, but that can be waived depending on your order potential.
Absolutely, they're AC/DC compatible, so you can use them in solar installations, switchgear, or any power transmission setup. The cold pressing process ensures consistent density for reliable performance in both current types.
We stock sizes from 1.5mm² up to 630mm², with screw diameters ranging from M4 to M25. If you need something in between or a custom size, we can do OEM/ODM as long as it fits our tooling.
Yes, our production is ISO 9001 certified, so you'll get consistent quality across batches. We can provide test reports or material certificates upon request — just let your sales rep know what you need.
