FZSW-33/10 Composite Polymer Horizontal Line Post Insulator

Composite insulators offer several advantages over conventional insulators made from homogeneous materials such as ceramic or glass. The use of two different materials, typically a fiberglass rod and a polymeric material for weather sheds, results in a more versatile and efficient insulating system. Here are some key points about composite polymer insulators:

1. Material Composition: Composite polymer insulators typically consist of three main components: an epoxy glass fiber core rod, silicone rubber sheds, and metal parts. This combination of materials provides a balance of mechanical strength, insulation properties, and resistance to environmental factors.

2. Hydrophobic Properties: The use of a synthetic material, particularly silicone, for the shed layer gives the insulator hydrophobic properties. This means that it repels water, making it suitable for outdoor use where exposure to rain and other environmental elements is common. The hydrophobic nature helps prevent the accumulation of dirt on the insulator surface, reducing leakage current losses.

3. Anti-Pollution Performance: The umbrella shed, made of silicone rubber, contributes to the insulator's strong anti-pollution performance. This is crucial for installations in areas with high pollution levels, as the shed's design helps prevent the accumulation of contaminants on the insulator surface.

4. Lightweight Structure: The use of lightweight polymeric materials, such as silicone rubber, results in a lightweight overall structure. This makes the assembly and installation of composite insulators more manageable compared to heavier traditional insulators made from ceramic or glass.

5. Reliable Structure: The design of composite polymer insulators ensures a reliable structure that is resistant to damage. The epoxy glass fiber core rod provides mechanical strength, and the silicone rubber sheds offer flexibility and durability. This combination helps maintain the integrity of the insulator under various environmental conditions.

6. Rod-Shaped Insulation Structure: The insulator belongs to the rod-shaped insulation structure, which is a common design for composite insulators. This configuration provides effective insulation along the length of the rod, making it suitable for high voltage installations.

Composite polymer insulators offer a technologically advanced solution with benefits such as hydrophobicity, anti-pollution performance, lightweight design, and a reliable structure, making them suitable for a wide range of high voltage applications, especially in outdoor environments.
