Covered line wire can be used as an insulated transformer wire, where the HMWPE insulation surrounding the conductor should not be considered electrical insulation, though it does reduce faults caused by weather, vibrations, and crossed leads.
Single conductors are available in solid or stranded, annealed or hardened uncoated copper.
Conductors are insulated with a concentrically applied LLDPE (linear low density polyethylene) that is Type I, Class A, Cat 5 and Grades E4-E rated. An optional Type II, III IV (MDPE and HDPE) insulation is available on request.
An optional XLPE (crosslinked polyethylene) insulation is also available upon request.
Print legends on the wire shall include the manufacturer, conductor size, voltage rating, UL symbol (if applicable) and type designation. Standard length spools are 500 or 2500 feet.
