    57-4 Ceramic Bus Post Insulator High Voltage Post Insulators


    Power lines and other electrified wiring transmission of high-voltage electrical energy along suspended cables. While the wires themselves generally do not contain insulation, certain points along the electrified wiring require insulation. For example, insulators are required where live electrical cables meet the poles supporting them and when placed in buildings. Since insulators do not respond to electrical fields, they can go a long way in preventing fires and electrical failures.


    The product offers many shapes during production. The enamel uses a wide range of colours according to clients’ needs, for example, grey or sky blue.


    Porcelain insulators do not present defects in the ceramic-metal interface. The combination of the ceramic insulator with cast iron or aluminium structures using traditional cementing agents is resistant to transition phenomena during electric discharge.
