PLP’s Complete Lineup of Polymer Line Post Insulator

15kV and 25kV Insulators Available Now!!!

PLP (formerly Preformed Line Products), a renowned industry leader, has once again added to its robust offering of insulators by adding the15kV and 25kV Polymer Line Post Insulator to its catalog.  PLP line post insulators are now available to cover all common distribution voltages in the US electrical grid and their insulators are proudly made in the USA. In this post, we'll explore the key features and benefits of PLP's LinePost Insulator and examine how PLP is poised to continue being a leading manufacturer to support electrical utilities and the distribution grid.

Key Features of PLP's Line Post Insulator:

  1. Advanced Design: PLP's Line Post Insulator boasts a cutting-edge design that optimizes performance while reducing its visual impact on the environment. Its sleek, modern appearance makes it a perfect fit for various applications and it’s tie top design is ideal for use with all PLP ties.
  2. High-Quality Materials: PLP has crafted this insulator using a proprietary high-density polyethylene-based compound that excel in withstanding harsh environmental conditions. This includes resistance to UV radiation, moisture, and extreme temperature fluctuations, ensuring a long and reliable service life.  It also utilizes a lightweight aluminum base.
  3. Durability: PLP's Line Post Insulator is engineered with UV-stabilized material that has a high impact resistance.  It meets and exceeds ANSI C29.18 for Specified Cantilever Load (SCL) and Specified Tensile Load (STL).
  4. ANSI Compliant: 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.  The insulators are ANSI C29.7 and ANSI C29.18 compliant and in some cases, exceeds standards for other categories such as Leakage Distance, Flashover (wet and dry), Impulse Flashover.  They have also been tested to include other ratings not listed in the standards such as the Maximum Conductor Temperature and Radio Influence Voltage (RIV).  
  5. Ease of Installation: Installing the Line Post Insulator is a seamless process. It is designed to be lightweight and easy to handle, reducing installation time and costs. It’s easily installed with an appropriate ¾” 10 UNC line post mounting stud (not supplied) into the bottom of the insulator and is compatible with a short shank or long shank line post stud.
  6. Outstanding Electrical Performance: The Line Post Insulator by PLP shines in electrical performance. It exhibits low leakage current and high insulation resistance, making it the ideal choice for power distribution networks where electrical efficiency is paramount.  It offers superior moisture and contamination shedding compared to porcelain insulators.
  7. MADE IN AMERICA: PLP’s line post insulators are proudly made in the USA at their manufacturing facility in Rogers, AR.

PLP continues to be a leading manufacturer and now offers a complete lineup of line post insulators as direct replacements for porcelain and composite insulators.  The insulators are made in the USA at their Rogers, AR facility and the central location of the plant is a benefit for all customers looking for quick delivery and the highest quality of material available to the market.  A list of catalog numbers is available below for quick reference.  Contact CBM for price and availability in Kansas, Missouri, Oklahoma, and Southern Illinois.
