Long Rod Suspension Insulator
Description
Technical Parameters
Gaodian Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of long rod suspension insulator in China. With abundant experience, we warmly welcome you to buy advanced long rod suspension insulator made in China here from our factory. We also accept customized orders.
Introduction
Long rod insulators are widely used in overhead transmission systems for insulation and mechanical support, especially in coastal and heavy polluted environment.
Key Advantages
Stays Dry. Resists Pollution. Needs Less Maintenance.
- Water-repellent surface – Water forms droplets instead of a continuous film, helping reduce leakage current.
- Hydrophobicity recovery – The silicone rubber can restore its water-repellent properties even when the surface becomes contaminated.
- Self-cleaning sheds – The shed profile helps rainwater remove dust and pollution while providing sufficient creepage distance.
- Reliable in polluted environments – Suitable for coastal, industrial and dusty areas where salt and contamination can affect insulation performance.
- Built for outdoor use – HTV silicone rubber offers good resistance to UV, ozone, acid rain and salt exposure for long-term operation.

FAQ
Q1: What is the difference between normal polymer suspension insulators and this one?
A: This series uses a compact shed design to improve cost efficiency while maintaining insulation reliability, and the shape of the sheds'X' can protect insulators from being eaten by birds.
Q2: Can this insulator be used in aging power grid upgrades?
A: Yes, of course. If full creepage distance is no longer required, we can have new design for same length but different creepage distance product. Anything is possible.
Q3: Do you have your own engineering team?
A: Yes. We have experienced technical team which can provide design and technical services.
Q4: What is the service life for this insulator?
A: The service life can exceed 30 years under normal operating conditions.
