Pure Copper Tin Coated Cable Lugs

Heavy Duty

WindyNation's pure copper tin-coated cable lugs are heavy-duty, pure copper, and are ideal for marine and humid environments because the tin coating protects the copper cable lug from corrosion and oxidation. If you need cable lugs for an outdoor installation on your RV, boat, car, truck, golf cart, off-grid wind, or solar installation, then WindyNation's tinned lugs are your go-to choice!

splice welding cable

Splice

Cables are precisely cut and stripped on automated robotic cable processing machines.

crimp welding cable lugs

Crimp

Cable lugs are attached using a 6 ton pneumatic crimper with custom dies, resulting in an ultra-strong, non-removable crimp.

heat shrink cable lugs

Insulate

After crimping, polyolefin heat shrink tubing is applied to eliminate the possibility of moisture or chemicals penetrating into the lug/cable interface.

Using these on a 3000W inverter and 300Ah 12v bank, pushing 275 amps at times. No issues. This is dense, heavy copper cable. Not as flexible as others claim to be and are, but I don't want flexibility when it means currency carrying capacity is reduced. This is beefy cable.

Excellent. I couldn't find this gauge in anything short enough. Came with connectors on each end.
