Insulator Testing Machine of Thermal-Mechanical Stress
The thermal-mechanical stress test is a sample test for composite insulators and porcelain insulators required in IEC. It tests insulators with the cycling of high temperatures and low-temperature environments.
- General Details
What is the thermal-mechanical testing machine?
The thermal-mechanical testing machine is designed to test the thermal-mechanical performance of the string insulator.
How are insulators tested in this thermal-mechanical test?
Insulators are loaded into the cabinet under room temperature. During the test, insulator units shall be subjected to four 24-hour cycles of cooling and heating, and to a tensile load equal to 60% of the specified electromechanical or mechanical failing load(as per IEC 383).
How many types of thermal-mechanical testing machines do you have?
Currently, we have 2 types of structure:
Vertical type
