15kV Polymer Suspension Insulator

15kV polymer suspension insulator is a high-performance solution designed for medium-voltage overhead distribution lines. Engineered with advanced polymeric materials, this insulator offers superior mechanical strength, electrical insulation, and environmental resistance—making it a reliable alternative to traditional porcelain insulators.

This model, FXB1-15/70CT, features a rated voltage of 15kV and a Specified Mechanical Load (SML) of 70kN, making it suitable for use in both standard suspension and tension applications. The high-strength FRP (fiber-reinforced polymer) core ensures structural integrity under mechanical stress, while the hydrophobic silicone rubber housing prevents surface water film formation, effectively reducing the risk of pollution flashover.

Key electrical performance includes a power frequency wet withstand voltage of 65kV and a dry lightning impulse withstand voltage of 140kV, offering dependable insulation performance under varied environmental conditions.

With a compact height of 380mm, a dry arcing distance of 195mm, and a creepage distance of 460mm, this 15kV polymer suspension insulator meets the stringent safety and performance requirements of modern power networks.
