It is mainly applicable to: GB/T1411-2002 Test for dry solid Insulating materials to withstand high voltage and low current arc discharge.
This testing machine is designed and manufactured in accordance with GB1411, IPC650, IEC 61621, ASTMD495, and complies with JEC 149, UL 746A and other test methods.
Scope of application: It is applied to the evaluation of arc resistance performance of insulating materials such as plastics, resin adhesives and insulating varnishes used in the electrical machinery, electrical appliances and household appliances industries. It is mainly applicable to the arc resistance performance testing of solid insulating materials such as plastics, films, resins, mica, ceramics, glass, insulating oil, insulating varnish, cardboard and other media.
Features: The arc resistance testing machine is computer-controlled, and the test curve can be observed online during the test process. It automatically stores test conditions, test results and other data, and can access, display and print them.
Test principle: It is used to test the arc resistance of solid insulating materials. The time when the material to be tested is exposed to a high voltage and gradually increasing small current environment until a stable conductive channel is formed on the material surface is the arc resistance time of the material.
