Introduction

Long Rod Insulators: NGK supply not only suspension (disc) insulators but also various types of long rod insulators.

  • Mechanical strength up to 400kN
  • Normal or alternating shed design with aero-dynamic type profile as per customer's requirements

Features:

  1. No Deterioration in Electrical and Mechanical Performance
    • Solid core porcelain -> Electrical puncture proof
    • No cement growth problem -> Stable mechanical performance
  2. Excellent anti-Contamination Performance
    • Less contamination accumulation due to aero-dynamic shed profile - Excellent anti-contamination performance under desert contamination condition.

Cautions:

Long rod insulator string has to be equipped with arcing horns to prevent shed breakage against power arc.
