The IEC/TR 60575 standard published by the International Electrotechnical Commission (IEC) describes performance test methods for overhead lines with alternating current and direct current nominal voltages higher than 1000 Volts. This standard also applies to insulators of similar design when used in substations. Also included in this standard are string insulator units of the header and pin type and string insulator units of the long rod type.
The aforementioned standard applies to long rod type, cap and pin type string insulator units with ceramic or glass insulating parts intended for AC and DC overhead lines with a rated voltage greater than 1000 Volts, as well as similarly designed insulators used in substations. This standard is considered in conjunction with IEC 60383 (IEC 60383 Insulators for overhead lines with a rated voltage above 1000 Volts).
Long-term tests or performance tests provide information that is essential to the operational reliability of insulators. This standard recommends a thermal-mechanical type test to test insulators in this respect. It also includes a mechanical test with load variations recommended as sample testing. The characteristics of the thermal-mechanical tests were chosen similar to established test practices in some countries. However, the influence of tolerances on certain factors specified in the tests, (eg temperature and load changes), and the influence of factors such as test load, number of load cycles and temperature variation, humidity conditions and the like must be considered.
The thermal-mechanical analysis method is used to characterize the physical properties of materials when force is applied at certain temperature and time periods. This analysis method is useful for investigating the properties of viscoelastic materials such as organic polymers. These materials exhibit both viscous and elastic properties that affect their response to mechanical stresses.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides thermal-mechanical performance testing and mechanical performance testing services on array insulator units, within the scope of IEC/TR 60575 standard, with its trained and expert staff and advanced technological equipment. gives.
