The risk of corrosion at cable connections stems from structural damage and environmental attacks. The key lies in selecting matching potting materials (such as cable polyurethane potting glue or epoxy potting compound) to achieve sealing, insulation and mechanical protection, so as to systematically "protect the connection" rather than just "complete the connection."

The​‍​‌‍​‍‌ choice of cable connections between epoxy resin potting and urethane potting compounds, for example, should be made on the basis of the application environment (e.g., mechanical protection, dielectric insulation, moisture protection, shock attenuation, etc.). A final decision should be made by carrying out the sample ​‍​‌‍​‍‌tests.
