Line Post and T&D Insulators

Newelll-PSN offers four different "classes" of solid core, line post porcelain insulators. And, because each and every insulator is subjected to tough performance testing, PRIOR TO BEING SHIPPED, you can confidently specify Newelll PSN.

Two Horizontal, Two Vertical Types

Newelll offers line posts for a broad range of transmission and distribution applications:

TWO BASIC HORIZONTAL LINE POST CLAMP-TYPE DESIGNS

  • GAIN BASE CASTINGS
  • STUD BASE CASTINGS

TWO BASIC VERTICAL LINE POST STUD-BASED DESIGNS

  • CONVENTIONAL TIE-TOP
  • CLAMP TOP

100% Puncture-Proof Solid Core

Solid core porcelain provides totally trouble-free electrical performance. The solid core design ensures 100% puncture-proof reliability throughout the insulator life.

Newelll-PSN is the best source for performance proven, solid core porcelain Line Post Insulators.

AUXILIARY HARDWARE AVAILABLE

Typically, insulators are supplied WITHOUT conductor clamps and mounting studs. All auxiliary hardware is available from Newelll-PSN.
