In addition to moisture-proof performance, the terminal should also be waterproof and prevent the harmful entry of solid foreign objects. The connecting device shall have an IP protection level corresponding to its classification against harmful entry. Whether it is qualified or not can be determined by performing the corresponding experiment in GB4208 on the connecting device of the cable with design requirements. After this experiment, the sample should be tested for electrical strength immediately.
In addition to ensuring moisture-proof performance, the terminal must also be waterproof and block solid foreign objects effectively. The IP protection level of the connecting device should match its classification to prevent harmful entry. Compliance can be verified by conducting the GB4208 experiment on the cable’s connecting device. After testing, the sample should immediately undergo electrical strength evaluation. How does the IP protection level impact the overall durability of the terminal?
