Composite Hollow Insulators for AC Voltage 35–1200 kV / Composite Hollow Insulators for DC Voltage ±400–±1100 kV

Product Application:
Used as insulation for high-voltage electrical equipment such as transformers and GIS (Gas-Insulated Switchgear) bushings.

Product Structure:
Mainly consists of an epoxy fiberglass cylinder, a high-temperature liquid silicone rubber shed assembly, and a flange.

Features:
  • Made of non-brittle materials, providing excellent explosion-proof performance;
  • High-temperature liquid silicone rubber offers strong hydrophobicity, making the product maintenance-free;
  • Excellent tracking resistance (4.5 kV) and high resistance to electrical erosion;
  • Lightweight, with good impact resistance — easy to transport and install;
  • Long service life, stable quality, and short delivery cycle.
