FXBW-001-1 Composite suspension insulator

1. Excellent Insulation Performance

Using organic materials such as silicone rubber as the insulating medium, it exhibits superior insulation properties, capable of withstanding high voltages and effectively preventing leakage current and flashover phenomena. The material’s high dielectric strength ensures reliable insulation in both normal and overvoltage conditions, meeting the requirements of ultra-high voltage transmission lines.

2. Strong Pollution Resistance

Silicone rubber has a low surface energy, making it less likely to adsorb pollutants. Additionally, its hydrophobic properties effectively suppress pollution flashovers in humid environments. Even when contaminated, the material’s surface can repel water droplets, maintaining insulation integrity and reducing the frequency of maintenance cleaning compared to traditional ceramic insulators.

3. High Mechanical Strength

The core rod is typically made of glass fiber-reinforced resin, offering high tensile and bending strength. It can withstand mechanical loads such as conductor tension, wind force, and ice/snow weight, ensuring structural stability in various meteorological conditions. Meeting the mechanical requirements of large-span overhead lines.

4. Lightweight Design

Compared to traditional ceramic or glass insulators, its weight is significantly reduced greatly facilitating transportation and installation. The lightweight feature reduces labor intensity during high-altitude operations and lowers the load on supporting structures , making it ideal for complex terrains and large-scale grid projects.

1. Low Operation and Maintenance Costs

Due to their excellent pollution resistance, the frequency of insulator cleaning and replacement is reduced, minimizing maintenance workload and costs. Additionally, their maintenance-free feature enhances the reliability of power grid operation by eliminating downtime caused by regular upkeep. This is particularly beneficial for long-distance transmission lines in harsh environments, where traditional insulators require frequent inspection and cleaning.

2. Excellent Anti-Aging Performance

Silicone rubber materials exhibit strong anti-aging properties, maintaining stable performance over long-term outdoor exposure to ultraviolet radiation, temperature fluctuations, and chemical corrosion. This ensures a service life of 20-30 years or more, significantly reducing the need for premature replacement compared to organic-inorganic hybrid insulators.

3. Brittle Fracture Prevention

Unlike ceramic insulators, composite suspension insulators are free from the risk of brittle fracture—a critical safety advantage. This eliminates power outages and safety hazards caused by insulator breakage, especially in high-voltage systems where sudden failure could lead to cascading grid faults. The ductile nature of silicone rubber and fiber-reinforced cores ensures gradual failure modes, allowing for timely detection and maintenance.

1. Electrical Insulation

Used in overhead transmission lines to reliably isolate live conductors from grounded structures , ensuring current flows along the conductors and preventing leakage to the ground or supporting structures. This maintains the safety of the power system by preventing accidental discharges and ensuring compliance with electrical insulation standards.

2. Mechanical Support

It bears the weight of conductors and various external forces. transmitting conductor tension to the poles or towers to ensure the mechanical stability of the line. Designed to withstand dynamic loads, it maintains proper conductor spacing and prevents mechanical failure that could lead to line outages.
