Burn Through (Cable Pull)Fiberglass conduit is an excellent material for avoiding “burn through” when pulling cable. | No | Yes | Yes | No | No | No | ||
Coefficient of FrictionUsing PVC Jacketed CableFiberglass conduit offers one of the lowest coefficient of friction available today for conduit systems. It is completely resistant to any of the current pulling lubricants corrosive properties. | 0.38 | 0.90 | 0.90 | 0.55 | 0.55 | 0.25 | ||
