Wire and Cable Solid Insulating Materials Arc Resistance Testing Equipment for UL 746A

Mainly applicable to:

GB/T1411-2002 dry solid insulation materials High voltage, low current arc discharge test.

Compliance with the standard: This tester 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:

The arc resistance of insulating materials such as plastics, resin glues and insulating paints used in electric motors, electrical appliances and household electrical appliances, etc. is mainly applicable to solid insulating materials such as: plastics, films, resins, mica, ceramics, glass , insulation oil, insulation paint, cardboard and other media arc resistance test.

Features:

The arc resistance tester is controlled by computer. The test curve can be observed online during the test. Data such as test conditions and test results can be stored automatically and can be accessed, displayed and printed.

Test principle: It is used to detect the arc resistance of solid insulating materials; that is, the material to be tested is exposed to a high-voltage, gradually-increasing current environment until a stable conductive path is formed on the surface of the material. At this time, the material is Arc resistance time.
