Model Specification – Polywater LZ 

Installer should use a minimum of 1 gallon of Polywater® LZ 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? LZ Lubricant.  The cable pulling lubricant shall provide excellent friction reduction with good cling and wetting through long pulls and multiple bends.  The lubricant shall leave minimal, non-combustible residue.  It shall be compatible with most cable jacket materials and be extensively tested on a broad variety of low smoke, halogen-free cable jacket materials.   

Cable jacket compatibility shall be tested with the specific LSZH jacket material used on the cable.  Test data shall be provided by the cable manufacturer or the lubricant manufacturer.  It 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.

A 15-gram sample of the lubricant, when placed in a one-foot, split metal conduit and fully dried for 24 hours at 105 degrees C, shall not spread a flame more than three inches beyond a point of ignition at a continued heat flux of 85 kW / meter2. Total time of test shall be one-half hour.
