126KV High Voltage Long Rod Composite Insulators

Product Overview

126kV high voltage long rod composite insulators are critical components for high voltage overhead transmission lines, engineered to provide exceptional electrical insulation and mechanical support in demanding power transmission applications. HAIVO's FXBW series long rod suspension insulators are designed to operate reliably at voltages up to 500kV, offering superior performance compared to traditional insulator strings.

These high voltage composite insulators feature a modular long rod design that eliminates the need for multiple insulator units, reducing installation time and maintenance costs. Manufactured in compliance with IEC 61109 standards, they incorporate advanced materials and manufacturing technologies to deliver unmatched reliability in the harshest environmental conditions, including high altitude, heavy pollution, and seismic zones.

Technical Specifications

Core Performance Advantages

Exceptional Anti-Pollution Performance

The long rod composite insulators feature a high-temperature vulcanized silicone rubber housing with excellent hydrophobicity and hydrophobic migration. This advanced material technology ensures that contaminants are easily washed away by rain, significantly reducing the risk of flashovers in heavily polluted industrial and coastal areas. The insulators are available with creepage distances up to 31mm/kV, making them ideal for use in extremely harsh environmental conditions.

Ultra-High Mechanical Strength

Our 126kV long rod insulators utilize high-strength modified ECR fiberglass core rods with a tensile strength exceeding 1200MPa. These rods offer exceptional resistance to creep, fatigue, and stress corrosion, ensuring reliable performance under continuous mechanical loads. The precision crimping process used to attach the end fittings results in uniform mechanical strength distribution and minimal performance variation between units.

Enhanced Structural Integrity

The one-piece design of our high voltage long rod composite insulators eliminates the weak points associated with traditional insulator strings. The seamless integration of the silicone rubber housing with the core rod and end fittings prevents moisture ingress and interface failures, while the internal radial multi-seal structure provides long-term sealing reliability. These insulators are also highly resistant to damage from vandalism and bird activity.
