The suspension porcelain insulator is made of porcelain parts, iron caps and steel feet glued with no less than 525 Portland cement and quartz sand adhesive. The contact surface between the iron cap and steel foot and the adhesive is thinly coated with a buffer layer, and the top of the steel foot is provided with an elastic pad. The surface of porcelain parts is generally painted with white glaze and brown glaze, and other glazes can also be painted as needed. All the surfaces of iron cap and steel foot are hot zinc. The push-pull elastic locking pin with ball connection has two types: W-type and R-type, which are made of tin bronze, brass and austenitic stainless steel. It has good elasticity and corrosion resistance, and is convenient for disassembly and assembly. Groove connected cylindrical and hunchback cotter pins, the former surface heat zinc, the latter made of brass. The above elastic locking pin, cylindrical pin and other parts are supplied in complete sets with the products.
The hanging white edge is generally formed by adhesive or mechanical bonding of insulated transition pieces (such as porcelain and glass) and metal accessory knives (such as steel feet, iron caps, flange sleeves, etc.). Insulators are widely used in power systems. They are generally external insulation and work under atmospheric conditions. The external live conductors of overhead transmission lines, power plants, substations and various electrical equipment shall be supported by insulators and insulated from the ground (or ground objects) or other conductors with potential difference.
Suspension porcelain insulators can be divided into AC insulators and DC insulators. The porcelain insulators produced by our company adopt high resistance insulation material formula, special umbrella structure and anti-corrosion design of metal accessories, which fully meet the harsh requirements of aging performance of DC transmission products. The design of various umbrella structures provides a variety of reasonable choices for hanging porcelain insulators, which is suitable for lines in different regions.
High voltage line antifouling disc suspension porcelain insulator is suitable for industrial dust, chemical industry, saline alkali, coastal and foggy areas. It is used for insulating and fixing wires of high-voltage overhead transmission and distribution lines. Generally, insulator strings are assembled on power lines in different voltage levels and polluted areas.
According to its umbrella structure, pollution resistant insulators can be divided into three types: double-layer umbrella, bell jar and straw hat. The pollution resistant insulator of double-layer umbrella has large climbing distance, open umbrella shape, smooth and boundless inner and outer skirts, low ash deposition rate and good self-cleaning performance in wind and rain. Bell jar anti pollution suspension insulator uses the incorrect damp state in the umbrella and the high angle of the umbrella to prevent discharge, which has good anti pollution performance. The disc diameter of straw hat antifouling suspension insulator is large. It is generally placed on the top of the suspension cable, which has a good effect on preventing bird injury and penetrating the icing. Refer to the general suspension insulator for the structural assembly of pollution resistant suspension insulator.

The pollution resistant insulator of double-layer umbrella has large climbing distance, open umbrella shape, smooth and boundless inner and outer skirts, low ash deposition rate and good self-cleaning performance in wind and rain. Bell jar type anti pollution suspension insulator, which uses the synchronous state of water in the umbrella and the high angle of the umbrella to prevent discharge, has better anti pollution performance.
