Currently the use of outdoor polymeric insulator materials are increasing in electrical distribution and transmission lines. One of them that are very popular is epoxy resins insulation material. There are several advantages of epoxy resins materials such as they have lower density mass, better dielectric properties, and higher volume resistivity compared to porcelain and glasses. However, there are some disadvantages in their application, for example: they are very sensitive in high temperature and in a very humid areas, and in the area receiving high intensity of ultra violet radiation, especially in tropical climate are still unknown well. The effect of silane treatment filler to the epoxy resins materials is expected to provide a better hydrophobic characteristic. Samples of silane epoxy resins materials were made from diglicydyl ether of bhisphenol-A cured by metaphenylene diamine using the value of stochiometric of unity. Then the 325-mesh silica filler treatment will be conducted by varying the silane composition in the room temperature vulcanized. The dimension of a sample was 70 mm x 70 mm with the thickness of 5 mm. The samples were laid upon an iron construction supporter about 8 m from the ground on Parangtritis beach, which is about 30 km away to the south of Yogyakarta city, for obtaining sea pollution in order to estimate their natural ageing performances. The investigation was carried out after 60 weeks later. Analysis of microstructure of the surface with SEM, indicate that the silane epoxy resins polymeric insulation materials with 60 weeks aging, compared with new materials and the degradation did not happen. Analysis of the chemical structure with FTIR also indicate that the silane epoxy resins polymeric materials after 60 weeks aging, compared with new materials and the chemical structure are not change.

“…Many research institutes, such as Japan, the former Soviet Union, Canada, Sweden and Chongqing University and Tsinghua University of China, exhibited a great interest in the flashover performance and mechanics of contaminated insulators and also conducted many investigations in an artificial climate chamber [13][14][15][16][17][18][19][20][21][22]. However, owing to the restriction of the field test conditions at high altitude sites, there is little research on the pollution flashover performance of long string insulators at high altitude site.…”

The ac pollution flashover performance and flashover process of LXHY 3 -I6O insulators was investigated at a high altitude site (altitude of 1400m) in this paper. The solid layer method was used, and even-rising voltage method was adopted. According to the test results, the average pollution flashover voltage (U av ) decreased with the increase of pollution, and there was no obvious relationship between the exponent characterising the influence of pollution and the length of the insulator strings. The relationship between U av and the length of the insulator strings was nearly linear. Subsequently, the effect of the pollution and the length of insulator strings on the critical flashover arc trajectory were analysed. It concluded that the critical flashover distance (l c ) decreased with the increase of pollution, and it was shorter than the leakage distance (L 0 ), whereas there was no significant relationship between l c /L 0 and the length of insulator strings. The arc appearance at the high altitude site was very irregular with obvious bending and rocking; the local arcs deviated from the surface of the polluted insulators even more seriously and the diameter was thicker than those obtained in the normal environment. Moreover, the brightness and diameter of local arcs was related to pollution.
