Product Description
220kV Composite Polymer Suspension Long Rod Insulator with High Strength Epoxy Fiberglass Core and Hydrophobic Silicone Rubber Sheds
220kV Composite Polymer Suspension Long Rod Insulator IEC61109
The 220kV composite polymer suspension long rod insulator is engineered for modern high-voltage transmission infrastructure. It features a high-strength epoxy fiberglass core and hydrophobic silicone rubber sheds, providing exceptional resistance to pollution, UV radiation, and aging in harsh environmental conditions.
For 220kV overhead lines, we strongly recommend installing corona rings. These components optimize voltage distribution at the end fittings and significantly reduce corona discharge, enhancing system performance and extending insulator service life.
Customization Options
- Available in multiple mechanical load ratings: 70kN, 120kN, or 160kN
- Custom designs available according to your specifications
- Multiple end fitting types: socket, ball, tongue, clevis, eye, and Y-clevis
- Full compatibility with diverse line hardware configurations
Manufactured to comply with IEC 61109 standards, this lightweight solution is ideal for long-span and compact transmission lines.
