Southwire® Industrial Power Cable products do not have a defined shelf life. These products are composed of hard goods (metal, polymer, etc., ...) that are designed for many years of service once installed. As long as the products are not damaged during storage/handling and they are stored in a facility that protects against exposure to weather (sunlight and precipitation), there should be no degradation to the electrical and mechanical performance of the products and no reduction in service life. When storing cable the following precautions should be considered

Strand-fll sometimes called moisture-block is a tar like substance that is applied between each lay-er of a concentric stranded copper or aluminum phase conductor. During the stranding process and at slightly elevated temperatures this tar like substance becomes fuid enough to be forced through a pump and applied geometrically in such a manner that the interstitial space between every strand is flled with the tar. The tar is then allowed to cool whereas it becomes stable and remains in place.

A dual rated cable is a cable that lists two different voltage ratings on its jacket. For instance, a cable with 115 mils insulation thickness may have a jacket with a print legend that lists both 5kV and 8kV voltages at 133% and 100% insulation levels respectively on it. Therefore, this cable may be used on both 5kV and 8kV systems.

The objective of this procedure is to provide a means of repairing jacket gouges, tears or indents in low and medium voltage cables. The purpose of the jacket is to protect the underlying elec- trical components from physical and environmental damage. The jacket is not part of the cable’s electrical system and therefore serves no dielectric purpose. Repairs should only be performed by qualifed personal.
