The INSULIGN Line Post Polymer Insulators are a direct replacement for high-voltage porcelain or composite insulators. They are designed to meet the dimensional, electrical, and mechanical requirements as defined in ANSI C29.18, Classes 51-1C, 51-1F, 51-2C, 51-2F, and 51-4F. By using ANSI head and neck dimensional standards, PLP formed wire ties (for bare or covered conductors) will install easily and provide superior holding and electrical performance. Consult PLP for the suitability of other formed wire tie brands with these insulators.

  • ANSI C29.7 and C29.18 compliant

  • Lightweight design – Less than half the weight of porcelain

  • Superior moisture and contamination shedding compared to porcelain

  • UV-stabilized material

  • ANSI - compliant head dimensions

  • Matched dielectric properties with covered conductor

  • High impact resistance

  • Manufactured from a proprietary high-density polyethylene-based compound

  • Tie top designs are ideal for use with all PLP ties

  • Utilizes a lightweight aluminum base
