| Selection Factor | What Buyers Should Verify |
|---|---|
| Electrical Insulation | Operating voltage, dielectric requirements and applicable testing standards |
| Moisture Protection | Enclosure design, cable entry sealing and required water-ingress testing |
| Gel Softness & Re-Entry | Target softness, adhesion, removal behavior and performance after aging |
| Flowability & Filling | Gel viscosity, filling depth, narrow gaps and potential trapped air |
| Mixing & Curing | Mix ratio, working time, curing temperature and production method |
| Packaging & Production | Manual filling, automated dispensing, cartridge or kit packaging |
Important: Final electrical insulation and water-sealing performance should be validated in the completed cable joint or enclosure, not determined from the gel’s properties alone.
| Requirement | Benefit |
|---|---|
| Electrical insulation | Helps protect cable connections |
| Moisture sealing | Reduces water-related failure risk |
| Soft gel structure | Low stress on wires and connectors |
