Isolateurs en porcelaine

This blog shows introduction of different types of insulator testers, which are designed to perform mechanical properties tests like tensile load, compression load, torsion load, cantilever load and etc, as well as electrical tests like electrical power frequency withstand voltage, power frequency flashover voltage, puncture voltage, steep-front test impulse voltage and etc. Each insulator testing machine or insulator production machine has specific function and necessity in technical requirements of international standards.
