PORCELAIN : Station Post Insulators

Image of Station Post InsulatorWe offer a complete line of station post insulators conforming to ANSI C29.9. We can even custom design post insulators to your specific requirements. We also offer a complete line of solid-core post replacements for your aging cap & pin insulators, offering both pedestal and tapped base versions.

Our semiconducting glazed station post insulators have set the standard for anti-contamination performance and long-term reliability. After over 30 years of research, development and field-testing, we have produced insulators that have a much higher contamination withstand voltage performance. Our low profile, solid core design lasts far longer in high contamination areas and eliminates costly maintenance, such as insulator washing and TV and radio interference. It features uniform surface drying and voltage distribution to prevent flashover, as well as dry-band arc suppression.

With station post insulators that feature our semiconducting glaze, you almost never have to worry about salt deposits or corona discharges. They feature:

  • Improved contamination performance
  • Improved RIV performance
  • Solid-core construction
  • Puncture proof body
  • Consistent mechanical strength
  • Long lasting durability

NGK-Locke supplies station post insulators with various mechanical ratings in accordance with ANSI standards.
