    X, XP high voltage line disc suspension porcelain insulator

    I. Use and Structure

    High-voltage line disc-shaped porcelain insulators are used for insulation and fixed conductors in high-voltage overhead transmission and distribution lines. They are generally assembled into insulator strings for circuits of different voltage levels.
    Ordinary insulators are suitable for general areas. If the number of insulators is appropriately increased, the pollution flashover performance can be improved.
    Suspended porcelain insulators are made of porcelain, iron cap and steel feet with no less than 525 Portland cement and quartz sand cement. The contact surface of the iron cap and the steel feet with the adhesive is thinly coated with a buffer layer, and the top of the steel feet is provided with an elastic pad. The surface of porcelain is generally painted with white glaze and brown glaze, and other glazes can be painted as required. The surface of the iron cap and steel feet are all hot zinc. There are two types of push-pull elastic locking pins with ball connection: W-type and R-type. Both are made of tin bronze, brass, and austenitic stainless steel. Grooved cylindrical and humpback split pin, the former is hot zinc, the latter is made of brass. The aforementioned elastic locking pins, cylindrical pins and other parts are supplied in complete sets with the product.
    Insulators are divided into ball type and slot type according to the connection method.
    The common and pollution-resistant insulators of the same strength class use the same ball and socket connection size to ensure interchangeability.
