Best Lubricant for Installing Transmission Cable, Pulling Through Water, and into HDPE Conduit Systems
* Polywater® + Silicone™ NN/NB is not recommended for LSZH/LSHF and certain CSPE and CPE cable jackets. For these jacket types, Polywater® LZ is the recommended/approved product.
are a family of high-performance, specification-grade, cable pulling lubricants that demonstrate superior performance in two areas: Friction reduction on HDPE (polyethylene conduits) and PVC materials. These lubricants provide continuous lubrication when pulling through water and are suitable for all types of cable pulling.
They are the industry preferred cable pulling lubricants for the longest pulls of heavy transmission cable and pulling cables in a wet environment. They are suitable for use with factory lubricated ducts. They continue to lubricate under high sidewall pressure forces in conduit bends. Both Type NN and NB are slow drying and leave a thin, slippery film that retains its slip for months after installations. While they can be applied by hand, it is best to pour or pump the lubricant into the duct during cable pulls.
Polywater® + Silicone™ is available with or without small plastic rollers in the lubricant. Type NB has the rollers and Type NN does not. In both Type NN and NB, a regular grade and winter grade (for cold weather use in temperatures as low as -20°F (-30°C)) are available.
Polywater® + Silicone™ can be pumped using the LP-D5 Drill-Powered Pump (see sidebar).
