The High Voltage Composite Station Post Insulator is specially designed for substations, offering high-performance insulation support for power equipment such as circuit breakers, voltage transformers, and switchgear. Made from premium composite materials, it delivers superior electrical insulation, mechanical strength, and long-term reliability-making it an ideal replacement for traditional porcelain insulators.
The insulator is composed of:
Core Rod: High-strength epoxy fiberglass rod for mechanical support.
Sheds: Weather-resistant silicone rubber, offering excellent hydrophobicity and anti-pollution capability.
End Fittings: Hot-dip galvanized steel fittings, firmly crimped or mechanically attached to ensure strength and reliability.
All materials are carefully selected for outdoor use, with outstanding UV resistance, aging performance, and chemical corrosion resistance.
