Post Insulator

APG-cast epoxy insulators provide void-free insulation, partial discharge <10pC, and custom creepage for 10-35kV.

  • Advanced APG or VPI process eliminates internal voids, reducing partial discharge below 10pC for long-term insulation reliability.
  • Customizable structural height, creepage distance, and shed diameter to meet non-standard specifications or tropical conditions.
  • 100% factory-tested for partial discharge, power frequency withstand, and X-ray inspection to ensure IEC compliance.

FAQ Related To Insulators
What is the difference between epoxy and composite insulators? Expand
Epoxy insulators (APG cast) are ideal for indoor switchgear. Composite insulators (silicone rubber) are better for outdoor or polluted environments.
What bending strength do your post insulators provide? Expand
Our standard post insulators provide bending strength ≥5kN (ZJ-10Q) to ≥6kN (ZJ-24Q/35Q). Higher strength options are available for special requirements
Can you manufacture insulators with custom mounting holes? Expand
Yes. We can customize mounting hole positions, thread sizes, and center distances based on your cabinet drawings.
