Electrical strength test machine for solid insulating materials
Summary:
The electrical dielectric strength tester is suitable for testing
the breakdown strength and withstand voltage of dielectric, such as
plastic, film, resin, mica, ceramic, glass, insulating paint and
other media at power frequency voltage.
