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

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.

I bought the 4/0 one foot cables. Far more flexible than I thought they would be. Seem to be well constructed. Pleased

I would say thgese are 2/0 equivalent, not 4/0. I bought 1 foot to connect a fuse to a Victron inverter, and the other side which is a different brand 4/0 cable stays cold, this 1 foot section gets real hot under load.
