1.High Mechanical Strength: The fiberglass core provides excellent tensile strength.
2.Excellent Insulation: The silicone rubber housing offers superior insulation properties.
3.Resistance to Contamination: Their hydrophobic surface prevents water and contaminants from adhering, reducing the risk of flashovers.
4.Lightweight Design: Easier to handle and install compared to ceramic or glass insulators.
5.Durability: They are resistant to corrosion, UV radiation, and extreme temperatures, which extends their service life.
6.Flexibility: The material can bend without breaking, providing better performance in high wind areas or under the weight of ice.
