Abstract

According to this study wax gel grease (S0) is formulated from base lube oil grade 260/290, transformer oil, microcrystalline wax, additives (0.1-2%) of Polyoxyethylene sorbiton-nano-palmitate antioxidant and 2, 2` methylene bis (4-methyl-6-tertiary butyl phenol) anticorrosion, was found that it had not well enough physico-chemical and dielectric properties, so other thicker may be used as (nano talc, nano kaolin, sodium silicate, ultramarine and silica from rice husk) and added to wax gel in certain proportions in an attempt to improve its physico-chemical properties (viscosity, penetration, dropping point and water resistance) and dielectric properties (dielectric constant, dielectric loss and volume resistivity) at frequency ranging 1-1000KHz at 35°C. Grease includes nano talc and silica from rice husk which has the best dielectric properties
