ヤマヨ試験器 List of Products and Services

This testing device is designed to conduct insulation breakdown voltage and dielectric strength tests on insulating films, insulating plates, etc., in a rational manner. The maximum output voltage can be manufactured up to AC100KV (standard) in alternating current. In insulation breakdown tests, dangerous high voltages are generated, and improper use may lead to fatal accidents. Our testing device has been designed with particular attention to safety, ensuring that even if the usage is incorrect, it will not lead to fatal accidents, allowing you to use it with peace of mind. 【Features】 ■ The tester is designed by the testers themselves, taking into account their perspective, making it easy to use and safe. ■ Safety devices to prevent electric shock are installed, so you can use it with confidence. (There is no worry about electric shock due to forgetting to turn off the switch.) ■ In the unlikely event that the overcurrent detector fails and the power supply is not cut off during insulation breakdown, we use an additional cutoff device to prevent the test transformer from burning out or causing a fire accident. *For more details, please download the PDF or feel free to contact us.
