- Product Description
-
Double umbrella anti pollution suspension porcelain insulator is a type of insulator designed specifically for high-voltage overhead transmission and distribution lines, especially suitable for industrial dust, chemical, saline alkali, coastal and foggy areas. Its main use is for insulation and fixing wires on high-voltage overhead transmission and distribution lines, usually assembled into insulator strings for use on power lines in different voltage levels and polluted areas.
Structural characteristics
Double umbrella type pollution resistant suspension ceramic insulators are divided into three types according to their umbrella shaped structure: double-layer umbrella type, bell jar type, and straw hat type. The double-layer umbrella type pollution resistant suspension ceramic insulator has a large creepage distance, an open umbrella shape, smooth and non angular skirt inside and outside, low dust accumulation rate, and good self-cleaning performance in wind and rain; The bell jar type anti pollution suspension ceramic insulator utilizes the different stages of moisture inside the umbrella and the high edge under the umbrella to suppress discharge, resulting in good anti pollution performance; The straw hat type pollution resistant suspension ceramic insulator has a large diameter and is generally placed at the top of the suspension string, which has a good effect on preventing bird damage and penetrating icing.
Model Description
The model XWP-70 represents a double-layer umbrella type pollution resistant suspension ceramic insulator, with the design sequence number in the lower right corner and the number after the dash indicating the mechanical and electrical failure load (kN). For example, XWP1-70 represents a pollution resistant suspension ceramic insulator with a design sequence number of 1 and a mechanical and electrical failure load of 70kN.
Applicable environment
Double umbrella type pollution resistant suspension ceramic insulators are suitable for various harsh environments, such as industrial dust, chemical, saline alkali, coastal and foggy areas. Its structural characteristics make it perform well in these environments, effectively preventing pollution and corrosion, and ensuring the stable operation of the power system.
Manufacturing materials and processes
Double umbrella type pollution resistant suspension ceramic insulators are generally composed of ceramic parts and metal accessories (such as steel feet, iron caps, flanges), which are glued together with adhesive or mechanically clamped. This structure enables insulators to perform well under mechanical and electrical stresses, ensuring the safe operation of the power system.
In summary, the double umbrella anti pollution suspension ceramic insulator plays an important role in high-voltage transmission lines due to its excellent anti pollution and mechanical properties, ensuring the stable operation of the power system.
