Abstract: In power systems, there is an ever-increasing demand placed on porcelain insulators especially for outdoor applications. Additionally, the huge cost of importation has resulted in a growing need for the local manufacture. To this end, an electrical porcelain insulator was manufactured from Ukpor Clay and other locally available raw material. Universal Composition of triaxial porcelain (kaolin, 45%; ball clay, 5%; feldspar, 25% and quartz, 25%) was used to produce a test piece. The pulverized and thoroughly mixed composition was compacted and fired at a temperature of 1200°C. The physical and Electrical properties were investigated. The results show that the sample has a breakdown voltage of 26kV/mm, low water absorption and dielectric constant between 9.0 and 10.9 within the frequency range considered. These results when compared with those of the commercial variety show that the locally manufactured sample satisfies the stringent requirements of a good insulating material.
