    XWP, XHP, XMP high-voltage line pollution-resistant disc-shaped suspension porcelain insulator

    I. Introduction to use, structure and model

    High-voltage line pollution-resistant disc-shaped suspended porcelain insulators are suitable for industrial dust, chemicals, saline-alkali, coastal and foggy areas, and are used for insulation and fixed wires on high-voltage overhead transmission and distribution lines. They are generally assembled into insulator strings for different voltage levels. 2. Power lines in different polluted areas.
    According to its umbrella structure, pollution-resistant insulators are divided into three types: double umbrella type, bell cover type and straw hat type. The double-layer umbrella pollution-resistant insulator has a large creepage distance, the umbrella is open, the skirt is smooth inside and outside without edges, the dust accumulation rate is low, and the wind and rain self-cleaning performance is good; the bell-type pollution-resistant suspension insulator uses different periods of moisture in the umbrella and The high edge under the umbrella inhibits discharge and has good anti-fouling performance. Straw hat-type pollution-resistant suspension insulators have large disk diameters. Generally, they are placed on the top of the hanging string, which has a better effect on preventing bird damage and penetrating icing. . For the structural assembly of pollution-resistant suspension insulators, please refer to ordinary suspension insulators.
