| Abstract: |
| Objective To study on the correlation between potting materials such as 267 silicone, DC160 silicone, 112FR epoxy resin and 8836 polyurethanein Xisha ocean atmospheric environment and laboratory environmental test. Methods Exposure test under shed was carried for 267 silicone, etc four potting materials in Xisha sea environment for 3 years, while damp heat test was carried out in the laboratory. The relevance of the two test environments was studied through testing surface resistance, volume resistance, dielectric constant, loss tangenty. Results The rank correlation coefficient between the laboratory accelerated test and the natural exposure test was 0.66, which was the average correlation between the volume resistance, the surface resistance, the dielectric strength and the loss tangent. They were strongly correlated. The accelerating coefficients of the four potting materials were 6.6, 4.9, 4.5 and 8.3 respectively. Conclusion The correlation between the potting materials and the hot and humid environment tests in the Xisha environment is established by the rank correlation coefficient method, which can provide basis for accelerated and simplified treatment of subsequent Xisha environmental test. |
