Model Specifications – Type NN

Installer should use a minimum of 1 gallon of Polywater® NN lubricant per 100 feet of cable pulled in. In poor conduit conditions, longer pulls and high conduit fill additional lubricant should be applied. 

The statement below may be inserted into a specific job specification to help maintain engineering standards and ensure project integrity.

The cable pulling lubricant shall be Polywater? Plus Silicone™ NN Lubricant.  The cable pulling lubricant shall provide a low coefficient of friction on a wide variety of cable jacket materials.  The lubricant shall leave a low solids residue of less than 4.0%.

The lubricant shall be compatible with the cable jacket material.  Cable jacket compatibility shall be tested by the IEEE 1210, Standard Tests for Determining Compatibility of Cable-Pulling Lubricants with Wire and Cable.  The lubricant shall not stress crack polyethylene per ASTM Standard 1693.  There shall be no significant changes in the conductive properties of XLPE and EPR semi-conducting compounds when the lubricant’s effect on volume resistivity is tested according to IEEE Standard 1210.

The lubricant shall not show a significant increase in friction coefficient over five water change cycles when tested through a water-filled duct via Telcordia test procedure TR-TSY-00356 Sections 4.1.3 and 4.1.4.  The cable shall not be re-lubricated during the test.
