We just pulled in about 5900' of 500 MCM that had Southwires new SIM PULL insulation. It was marked no lube, but at runs of 470' I wasn't taking any chance not using lube.

Has anyone else used this wire and if so what are your thoughts?

The Southwire rep. says they guarantee their product, but it will take a little getting use to before I give up using wire lube, especially when pulling big wire.
