Best Lubricant for Installing Transmission Cable, Pulling Through Water, and into HDPE Conduit Systems
Polywater® + Silicone™ Type NN is a high-performance, specification-grade, cable pulling lubricant that demonstrates superior performance in two areas: Friction reduction on HDPE (polyethylene conduits) and PVC materials. This lubricant provides continuous lubrication when pulling through water and is suitable for all types of cable pulling.
Type NN is the industry preferred cable pulling lubricant for the longest pulls of heavy transmission cable and pulling cables in a wet environment. It is suitable for use with factory lubricated ducts. It continues to lubricate under high sidewall pressure forces in conduit bends. Type NN is slow drying and leaves a thin, slippery film that retains its slip for months after installations. While it can be applied by hand, it is best to pour or pump the lubricant into the duct during cable pulls.
* Polywater + Silicone NN is not recommended for LSZH/LSHF and certain CSPE and CPE cable jackets. For these jacket types, Polywater LZ is the recommended/approved product.
Type NN is available in both regular grade and winter grade (for cold weather use in temperatures as low as -20°F (-30°C)). Polywater + Silicone can be pumped using the Polywater® Lubricant Pump Drill-Powered Model LP-D5.
Specifications and Applications:
Cable Compatibility: Passes IEEE 1210 physical and electrical testing on a wide variety of cable materials. Cable manufacturer approvals available upon request.
Friction Testing: Shows excellent lubricity on a variety of cable jacket types. Using HDPE conduit, the following COFs were measured: LLDPE .05, PVC .08, XLPE .07, CPE .08, PP .07. Method described in “Coefficient of Friction Measurement on Polywater’s Friction Table, 2007.” Typical values determined using 200 lbs./ft. normal force.
Coatability: Polywater + Silicone NN will wet out evenly on cable jacket surfaces. Using the Telcordia test procedure TR-TSY-00356 Sections 4.1.3 and 4.1.4, a cable was subjected to 5 separate pulling cycles through a water-filled duct and the COF was measured showing excellent friction reduction and lubricant adherence to the cable.
Temperature Range: Has a wide temperature use range: 20º F to 120ºF (-5°C to 50°C). Polywater WNN (Winter Grade): -20°F to 120°F (-30°C to 50°C)
