“…Isolator pemasangan luar yang populer dikembangkan saat ini adalah isolator berbahan polimer, dikarenakan bahan polimer mempunyai banyak kelebihan dibandingkan bahan porselin dan gelas. Di antaranya adalah mempunyai sifat hidrofobik yang tinggi, mempunyai rapat massa yang lebih rendah, mudah dibuat karena tidak memerlukan suhu yang sangat tinggi dalam proses pembuatannya, dan mempunyai tingkat kerekatan yang tinggi [9].…”

Penggunaan serat alam sebagai filler dalam bidang industri masih terus dikembangkan, mengingat sifatnya yang ramah lingkungan dan mengandung material yang besar. Penelitian ini dilakukan untuk mengetahui pengaruh eceng godok dan sekam padi sebagai filler pada material resin epoxy. Pembuatan spesimen menggunakan metode hand lay-up dengan masing-masing variasi filler 10%-40% dari berat total bahan uji dan spesimen tanpa filler 0% sebagai pembanding. Bahan polimer yang digunakan yaitu resin epoxy. Pengujian yang dilakukan yaitu uji tarik,uji resistivitas permukaan dan resistivitas volume. Uji tarik dilakukan menggunakan standar ASTM D-638 dan uji resistivitas menggunakan standar ASTM D 257. Hasil pengujian menunjukkan bahwa nilai resistivitas volume maksimum dicapai dalam kadar eceng gondok 20% sedangkan pada sekam padi peningkatan resistivitas volume terus terjadi sampai kadar 40% dari resin epoxy. Peningkatan resistivitas permukaan berlanjut hingga kadar eceng gondok mencapai 20 % pada resin epoxy begitupun dengan penambahan filler sekam padi. Kekuatan tarik dari material resin epoxy mengalami penurunan dengan penambahan eceng gondok dan sekam padi. Nilai kekuatan tarik maksimum dicapai pada komposisi filler 20%. Dengan bertambahnya kadar eceng gondok dan sekam padi didalam resin epoxy, sifat getas dari material resin epoxy semakin meningkat atau terjadi peningkatan kekerasan dari resin epoxy sehingga mengakibatkan kerapuhan

“…When polymer insulators are installed in tropical climates, pollutant particles that are sticked to the surface of the insulators cause the occurrence of impurities. This condition will be worse in the wet season where the leakage current will flow to the ground trough the grounding system due to the conductive layer that has been formed by the impurities on the surface of the insulator [2]. This situation can lead to the occurrence of the dry bands on the surface of the insulator, in which at the end can also cause the electric arc or Partial Discharge (PD).…”

One of the important components in the high voltage overhead lines placed on the transmission tower is an insulator. Insulators that are installed outdoor will be exposed to the environment directly. Due to environmental conditions and pollutants attached to the surface, leakage currents can flow on the surface of the insulator. Large leakage currents can damage the surface of the insulator and cause losses in the form of heat and even cause flashover. This paper provides an alternative way to prevent early flashover by detecting the severity of the insulator surface based on harmonic measurements of leakage currents. Insulator performance mainly depends on the conductivity of the surface layer being polluted or by generating pollutants via the equivalent salt deposit density (ESDD). The leakage currents were evaluated at different ESDD levels as deposits of very light, light, moderate, and heavy NaCl salt pollution on a 20 kV outdoor polymer insulators. From the experiments, it can be concluded that: i. The leakage current that occurs when the surface of the insulator is very lightly polluted has an unsymmetrical waveform that is distorted and leads to a positive with a large THD; ii. The magnitude of the leakage current with the surface of the insulator is polluted, which leads to greater weight, but the harmonic distortion and THD are getting smaller with the waveform of the leakage current signal leading to a sinusoidal waveform.

“…Since last few years, the silicone rubber and epoxy resin have great potential in industry because of their use as alternative material of ceramic and glass and its properties, like dielectric, volume resistivity, mechanical strength, thermal conductivity and light weight (Fernando and Gubanski, 2010;Manjang and Nagao, 2011;Lau and Piah, 2011;Kitta et al, 2016;Gençoğlu, 2016). Due to their light weight, it is easy to use and control than other ceramic and glass materials (Zhu et al, 2016).…”

Coal power plants are the major contributor of electricity but these power plants are also producing waste in the form of coal fly ash (CFA). However, it can cause high risk of environmental pollution and pulmonary diseases in humans. Plastic waste is also a problematic waste for many countries in terms of its reuse and recycling. Therefore, this study aims to reuse the waste product (CFA) of coal power plants in rubber conveyer belt instead of calcium carbonate or talcum powder and in recycling of plastic propylene as bonding filler material instead of barium sulfate to increase the durability of plastic products and reduce cost, CFA waste and plastic waste. For this purpose, CFA was treated by different pulverization techniques for the production of conveyor belt. The study found that the most favorable technique was shear based pulverization technique. Application of CFA with rubber was compared with two different chemicals (calcium carbonate and talcum powder) and found that the elongation at break of conveyor belt was 35% increased and abrasion volume was 64% reduced by using treated CFA. Furthermore, CFA was used in molten mass of plastic instead of barium sulfate and the results showed that the use of CFA has improved the dimensional stability of plastic material reducing the cost per ton by 2410 CNY. The study concluded that the performance was increased by applying CFA with a reduction in price as compared to other chemicals.
