As a professional manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is dedicated to providing reliable and high-performance solutions for the global power transmission industry. Our 110kV Polymer Composite Suspension Long Rod Insulator with Silicone Rubber Housing represents a significant advancement in insulator technology, designed to meet the demanding requirements of modern high-voltage networks. Combining superior electrical insulation with exceptional mechanical strength and environmental resilience, this product offers a durable and cost-effective alternative to traditional ceramic or glass insulators, ensuring long-term stability and reduced maintenance costs for your infrastructure.
The insulator is engineered with a focus on performance and longevity. Its core construction utilizes a Fiber Reinforced Polymer (FRP) rod, which provides high tensile strength and excellent resistance to bending forces. The rod is encapsulated in a high-grade silicone rubber housing, which is meticulously molded to form a protective shed design. This design is crucial for enhancing the creepage distance and ensuring reliable performance even in contaminated or humid environments. The silicone rubber material offers outstanding hydrophobic properties, meaning water droplets bead up and roll off the surface, preventing the formation of continuous water films that could lead to flashover. This self-cleaning characteristic significantly improves performance in rainy or polluted conditions.
Key Technical Specifications and Advantages:
- Enhanced Mechanical Performance: The FRP core offers a high strength-to-weight ratio, making the insulator lighter than traditional types while maintaining robust mechanical load capacity. This reduces stress on support structures and simplifies installation.
- Superior Electrical Insulation: The composite design and silicone rubber housing provide excellent dielectric strength, ensuring safe insulation at 110kV and higher transient voltages.
- Exceptional Environmental Resistance: The product is highly resistant to UV radiation, temperature extremes (both high and low), acid rain, and salt spray, making it suitable for diverse geographical applications from coastal areas to industrial zones.
- Long Service Life: The materials are selected for their aging resistance, contributing to a long operational lifespan with minimal degradation, which translates into lower lifecycle costs.
- Lightweight Design: The composite insulator is significantly lighter than porcelain or glass counterparts, leading to easier handling, transportation, and installation, reducing labor and logistical costs.
- Anti-Bird Damage Design: The smooth surface and material properties help deter bird pecking damage, a common issue with some insulator types.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a polymer composite insulator over traditional porcelain or glass types?
A: Polymer composite insulators, especially those with silicone rubber housing, offer significant advantages including lighter weight, higher mechanical strength, better resistance to vandalism and bird damage, superior performance in polluted environments due to hydrophobic surfaces, and generally longer service life with less maintenance. -
Q: How does the silicone rubber housing improve performance in wet or contaminated conditions?
A: Silicone rubber possesses excellent hydrophobic properties. This means water forms discrete beads on its surface rather than a continuous film, drastically reducing the risk of surface tracking and flashover under wet or polluted conditions, effectively providing a self-cleaning effect. -
Q: Can the mechanical load rating (ML) of this insulator be customized?
A: Yes. We offer insulators with various mechanical load ratings (such as 120kN, 160kN, 210kN, etc.) to suit different line design requirements. The specific rating can be selected based on your project's mechanical load calculations. -
Q: What is the typical service life expectancy of this product?
A: Under normal operating conditions, our polymer composite insulators are designed for a long service life, often exceeding 30 years. The high-quality FRP core and specially formulated silicone rubber are resistant to aging from UV, temperature, and environmental stresses. -
Q: Are these insulators suitable for coastal areas with high salt content?
A: Absolutely. The silicone rubber housing provides excellent resistance to salt spray and corrosion. This makes them a preferred choice for transmission lines near coastlines or in industrial areas with atmospheric pollution. -
Q: What connection types are available for these suspension long rod insulators?
A: Standard connection types include ball & socket fittings compatible with common hardware. Other connection types can be available upon request to match existing tower hardware or specific design standards. -
Q: Does your company provide testing reports or certificates for the products?
A: As an ISO9001 certified manufacturer, we conduct rigorous quality control and testing. Relevant test reports (such as mechanical load tests, electrical tests) can be provided upon request to support your project documentation and compliance needs. -
Q: How does the lightweight feature benefit installation?
A: The reduced weight compared to porcelain insulators makes handling, transportation, and on-site installation much easier and safer. It can lower labor costs, reduce the need for heavy lifting equipment, and minimize installation time.
