Ground Wire Insulator Tubes

Ultimate Protection with Ground Wire Insulator Tubes.

PUPI® fiberglass ground wire insulator tubes are made of high performance pultruded fiberglass to provide superior ground wire isolation and dielectric protection. Protected by SunGUARD® UV coating, our ground wire insulator tubes offer the same three levels of UV and weathering protection as PUPI tangent and deadend crossarms.

 

Ground wire insulator tubes are available in 10’ length increments and can be cut on-site to meet specific customer needs.
