Use and Classification

High voltage line disc suspension porcelain insulator
High-voltage line disc-shaped suspension porcelain insulators (hereinafter referred to as insulators) are used for insulation and fixed conductors in high-voltage overhead transmission and distribution lines. Generally assembled into insulator strings for use on lines of different voltage levels. Insulators are divided into common type and pollution-resistant type according to their use environment and region. Ordinary insulators are suitable for general areas. If the number of insulators is appropriately increased, the stain resistance can be improved. Pollution-resistant insulators can be divided into three types according to their umbrella structure: bell type, double umbrella type, 3 umbrella type. Pollution-resistant insulators are suitable for industrial dust, chemical industry, saline-alkali, coastal and foggy areas. Different structural types The best use range of pollution-resistant insulators needs to be summarized and determined after trial operation.
Insulators are divided into ball type and groove type according to the connection mode.
