Aerodynamic Glass Insulators Description:

Aerodynamic glass insulators are used in AC high-voltage, high-voltage and extra-high-voltage transmission lines to suspend, tension and insulate between wires and towers. Strength grade 40~550kN.

Aerodynamic Glass Insulators Features:

1, zero-value self-breaking, easy to detect, reduce labour intensity, can save the line maintenance costs to a large extent;
2, Good resistance to industrial frequency arc and vibration;
3, self-cleaning performance is good and not easy to age;
4, high dielectric constant of glass, insulator string voltage distribution uniformity;
5, running, self-broken after the residual hammer has enough mechanical strength, will not fall off the line.
