Accordingly, there is provided a high fault current proof insulator for high voltage electrical appliances comprising an epoxy body, a high tension (HT) conductor and locking system. The epoxy body comprises brass/steel sleeve and a grounded aluminum/steel terminal. The grounded terminal being configured on an outer surface of the epoxy body, the HT-conductor being inserted through the epoxy body to serve as an electrical connection between an electric appliance and a power supply source. The HT-conductor is configured as a separate replaceable component being assembled in the brass sleeve by means of suitable locking arrangement. The copper conductor (HT conductor) has provision for sealing arrangement to extend this connection from one medium to another. The grounded terminal is also provided with appropriate sealing arrangement to meet this requirement. In highly polluted areas, the performance of the insulators and the connections can be achieved by controlling the environmental conditions of the terminal box. The controlled environment of terminal box would be possible using pressurized gas like Nitrogen, air etc. No. of Pages : 13 No. of Claims : 7
