Faster Installs, Lower Lifetime Costs
When it comes to long-term performance in overhead distribution, Hendrix Vise Top Line Post Insulators offer clear advantages over porcelain.
Traditional porcelain insulators are prone to cracking, combustion, and failure—especially under extreme weather or wildfire conditions. Hendrix VTLP insulators are molded from a high-durability HDPE blend that resists fire, impact, and UV degradation. They’re also significantly lighter, reducing installation time and the risk of breakage during handling. With no ties required and direct interchangeability with porcelain, utilities save time, labor, and replacement costs. For utilities focused on system hardening, safety, and reducing total cost of ownership, Hendrix is the trusted choice.
