Composite Support Insulators for AC Voltage 110–1100 kV / Composite Support Insulators for DC Voltage ±400–±1000 kV

Product Application:
Support insulators are key components widely used in medium- and high-voltage power transmission and distribution systems. They serve to insulate and support live parts of electrical equipment.

Product Structure:
Mainly consists of an epoxy fiberglass cylinder, high-temperature liquid silicone rubber housing, grading ring, flange, and density relay.

Features:
  • Unique umbrella-shaped design
  • Double-layer voltage grading ring on the top effectively improves external electric field distribution, with a radio interference level below 500 μV;
  • Excellent tracking resistance (4.5 kV) and high resistance to electrical erosion;
  • Outstanding mechanical properties;
  • Lightweight, easy to transport and install;
  • Stable and reliable quality with short delivery cycle.
