RoHS Compliant Made in USA


Covered Line Wire is used in uninsulated transformer wire applications, providing excellent mechanical, abrasion, moisture, chemical and oil resistance. For this application, the HMWPE is not considered an electrical insulation; however, it does reduce faults due to atmospheric conditions, vibrations, and crossed leads.

Applicable Standards and Tests:

ASTM B-1, B-3, and B-8, ASTM D-1248, NEMA WC-5, ICEA S-61-402, ICEA S-70-547, ICEA S-95-658/NEMA WC70, CSA C68.9, Spark tested at 7500 VAC



Single copper conductors are solid or stranded, annealed or hard uncoated copper.


Black, sunlight resistant polyethylene with concentrically applied insulation, Type I, Class A, Cat 5, and Grades E4-E5. Types II, III, and IV (MDPE and HDPE) are available on request.
