“…6 For example, addition of 1-2.5 wt% nanoclay into the epoxy matrix made them more resistant to tracking, since the exfoliated clay acted as a barrier and limited tracking, while the pure polymer burnt vigorously during the tests. 7 Similar effects on the tracking properties were reported for various ame retardants in poly(butylene terephthalate). 4 The ammability and CTI tests also conrmed that diethylphosphinic acid aluminum salt which forms condensed form of char enhances the ame retardant properties.…”

AbstrakRiset terhadap bahan isolator polimer yang lebih ringan dan dapat ditambahkan pengisi untuk memperbaiki kekuatan isolator masih menjadi sebuah riset, namun kondisi lingkungan akan mempengaruhi kinerja pada isolator polimer di luar ruangan. Pada penelitian ini dilakukan pengukuran arus bocor kondisi basah terhadap permukaan bahan isolator dengan metode pengukuran Inclaned-Planed Tracking (IEC 587:1984) dengan kontaminan NH 4 Cl dan air hujan. Sampel pengukuran menggunakan bahan isolasi resin epoksi yang terbuat dari campuran DGEBA dan MPDA dengan campuran bahan pengisi silicone rubber dan fly ash. Penuaan dipercepat dilakukan dalam kotak pengukuran yang terdapat paparan radiasi ultraviolet. Parameter yang dianalisa adalah sudut kontak, arus bocor lucutan pertama dan arus puncak. Hasil pengukuran menunjukkan semakin lama radiasi ultraviolet menyebabkan penurunan hidrofobik permukaan dan meningkatnya nilai arus bocor. Penggunaan polutan dengan nilai konduktivitas tinggi menyebabkan semakin tingginya arus bocor lucutan pertama dan arus puncak pada permukaan isolator. Didapatkan penggunaan komposisi pengisi terbaik terdapat pada sampel uji RTV23 dibandingkan RTV22 dan RTV24 dengan daya tahan sudut hidrofobik paling stabil sebesar 48.56% dan rata-rata kenaikan nilai arus bocor lucutan awal sebesar 31.16% dan arus puncak 10.76% terhadap penuaan radiasi ultraviolet.Kata kunci : resin epoksi, fly ash, variasi kontaminan, penuaan dipercepat, sudut kontak, arus bocor. AbstractResearch on polymer insulator material that is lighter and can be added filler to improve the strength of the insulator is still a research, but environmental conditions will affect the performance of outdoor polymer insulators. In this research, we measured leakage current in wet condition on surface of insulating material with Inclaned-Planed Tracking measurement method (IEC 587:1984) with contaminant of NH4Cl and rainwater. The measurement sample used an epoxy resin insulation material made from a mixture of DGEBA and MPDA with a mixture of silicone rubber and fly ash. Accelerated aging is done in a measurement box with exposure of ultraviolet radiation. Parameters analyzed were contact angle, first leakage current and peak current. The measurements show longer ultraviolet radiation causes decrease in surface hydrophobicity and increased value of leakage current. The use of pollutants with high conductivity values leads to higher leakage current first and peak current on the surface of the insulator. The best use of filler composition was found in RTV23 test sample compared to RTV22 and RTV24 with the most stable hydrophobic of 48.56% and an average rise in initial discharge leakage value of 31.16% and a peak current of 10.76% against aging of ultraviolet radiation.

“…For safety reasons and consideration factors towards the detrimental health of the insulation systems researchers are showing keen interest on surface degradation and dielectric breakdown of the polymeric insulating materials. Guastavino et al [18] performed tracking test on different wt% of nanoclay and microsilica filled epoxy composites. They concluded that 1 wt% nanoclay with 53.5 wt% silica and 2 wt% nanoclay with 53 wt% silica composites showed better resistance to tracking.…”

The tribological and electrical properties of epoxy composites filled with nano‐sized silica particles are studied and discussed in this article. To enhance the interfacial interaction between the fillers and the matrix, nanoparticles were pretreated with silane coupling agent. Dry sliding wear tests were carried out with configuration of composite sample on a rotating steel disc. Electrical measurements such as AC breakdown voltage, at 50 Hz, high voltage‐low current arc resistance and wet tracking resistance were carried out. The results reveal the influence of nanosized silica loading on wear resistance of the epoxy. It is observed that 10 wt% loading of silica is very effective in reducing the wear loss. With further increase of silica filler loading, the nanoparticles agglomerated and resulted in increase of the specific wear rate. The influence of silica particles on the specific wear rate is more pronounced under sliding wear situation. The influence of silica particle loading on epoxy is evident in the results of electrical parameters like dielectric strength, arc resistance and tracking resistance. These parameters showed improvement with filler loading up to 15 wt% and beyond this value of filler loading noticeable deterioration was observed. The effects of electrical stresses in the morphologies of the surfaces of epoxy nanocomposites are discussed. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers
