Transmission Line Tools 240kn Anti-pollution Type Standard High Voltage Suspension Glass Insulators
Insulators are one of the key components of high-voltage transmission lines, and their performance directly affects the operation safety of the entire transmission line. Glass insulators are widely used because of their zero-value self-breaking and easy maintenance.
With glass insulators, it is possible to eliminate the periodic periodic preventive test of the insulator during operation. This is because every damage to the tempered glass will cause damage to the insulator, which is easy for the operator to find when patrolling. When the insulator is damaged, the glass fragments near the steel cap and the iron foot are stuck, and the mechanical strength of the remaining portion of the insulator is sufficient to prevent the insulator string from breaking off. The self-slope rate of glass insulators is one of the important indicators to measure the quality of products. It is also the quality basis for bid evaluation at the time of bidding.
Insulators will not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, insulators will not play a significant role and will damage the use and service life of the whole line.
