High voltage insulators are essential element for a reliable performance of electric power systems, these insulators are classified into ceramic insulators (porcelain and glass types) and non-ceramic insulators (polymers), the use of polymers became important due to their good properties over porcelain and glass types. One of the most important characteristics on which the choice of electrical insulators depends on is the dielectric strength of the insulator. This paper investigated the electrical properties (dielectric strength) of Polyvinyl chloride (PVC) cables that are used in high voltage by loading Alumina Trihydrate (ATH) filler under different temperature conditions. The results showed improvement of the dielectric strength with increasing the ATH content in the composite samples also the value of dielectric strength is inversely proportional with temperature condition
