The epoxy bonded hollow insulator samples suffered different artificial environments were tested to compare their bonding strength in terms of bending strength. The samples were made of the same material as the 550 kV hollow insulator. The test data were processed with variance analysis. The results show that the artificial environments of high/low temperature, water immersion, ultraviolet radiation, ozone and 1% hydrofluoric acid solution impose no significant effect on the surface of the samples, however, 5% hydrofluoric acid solution imposes significant effect on the bonding strength of the samples.

The ±800 kV DC electronic current transformer development background, working principle, technical parameters, the main components, design and development situation of the main structure, experiments of the major projects were introduced. The technical comparison with foreign products, and reliability analysis were carried out in several key aspects. The results show that the ±800 kV DC electronic current transformers which are independently developed in China are reached the very similar level of international products. Source
