Product quality is the foundation for the survival and development of enterprises. It is the responsibility of enterprises to provide consumers with high-quality, safe and reliable products. With the continuous upgrading of China's consumption level, consumers' demand for high-quality products is also increasing. However, the products in the market are uneven. How can consumers buy high-quality products? Through product underwriting, both enterprises and consumers can have an extra layer of protection. China's authoritative insurance groups will not insure inferior products. They must pass strict qualification review before they can pass.

In order to ensure accurate measurement of the test values ​​of the insulation layer resistance R15s and R60s of the photovoltaic cable, we generally use a large-capacity insulation resistance tester with fast charging speed. According to relevant regulations in my country, the output short-circuit current of the insulation resistance tester should be greater than 0.5mA, 1mA, 2mA, and 5mA, and in situations with high requirements, an insulation resistance tester with a larger output short-circuit current should be selected as much as possible.
