Most of these get spec'd into transmission line projects where you're running overhead conductors between towers—that's the bread and butter use case, and we see them ordered for 40kN up to 120kN tension ranges depending on the span load. They're made from a special alumnum alloy that's non-magnetic, so what it does is reduce line loss compared to standard steel clamps, and the hot-dip galvanizing is pretty thorough on the surface (usually holds up for years in coastal or industrial environments).
The U-type body is smooth, no sharp edges or burrs, which matters when you're pulling through or handling near energized lines—it's a detail you'd notice if you've ever had a jacket snag on a rough clamp. Bolts are grade 6.8 or above, and we torque-test them at the factory, but you'll want to verify your own installation specs anyway. Also the surface finish is silver from the galvanizing, not painted, so it's better than painted clamps for weather resistance.
It's built to IEC and ANSI standards, which basically means it passes the same mechanical and electrical tests that project engineers look for—we've got ISO 9001 on the manufacturing side, so batch consistency is typically tight. 2-4 weeks lead time is normal for standard orders, but if you need a custom marking or a different bolt length, OEM runs take about 30 days or so (lead time depends on spec change). They come in bulk cartons of 20, 50, or 100 units depending on the size you order.
40 to 120kN capacity covers most common distribution and sub-transmission lines, but it's not suited for EHV or ultra-high tension application where you'd need a different clamp design entirely. We've seen some buyers use these for guy wire terminations too, though that's not the intended application—check with your structural engineer first. The electricla performance is fine for standard AC lines, but we don't have data for DC or high-frequency use.
MOQ is usually 50 pieces for standard sizes, though we can do less on a special request (price per unit goes up a bit). COA comes with every batch from our test lab, typically showing the 0.2% proof stress and galvanizing thickness. One thing most buyers don't think to ask: the bolts are zinc-plated, not galvanized, so if you're in a high-salt enviroment, you might want to upgrade to stainless hardware separately.
Our MOQ typically starts at 200 pieces per model, but we can adjust based on your project needs. Just reach out with your volume, and we'll work something out.
For standard orders of the Tension Clamp Series, lead time is around 15-20 working days after confirmation. Custom specs might add a few more days.
Yes, we include ISO 9001, IEC, and ANSI compliance certificates with each batch. Third-party testing reports are also available if requested.
The standard range is 40-120kn, but we can adjust the design for higher or lower loads through OEM/ODM. Just share your specific requirements.
Keep them in a dry, covered area away from moisture and chemicals. The hot-dip galvanized finish resists corrosion, but proper storage maintains the smooth surface.
