            110kV-1100kV GIS Inlet/outlet line Bushing
            • Description
            • Parameter

            110kV-1200kV GIS Inlet/outlet line Bushing

            Structure: composed mainly of composite hollow insulator, end grading ring, heat dissipating cage, high-voltage terminals, center conductive rod, core shielded electrode, epoxy post insulator and quincunx contact.

            Features:

            ² Excellent design effectively improves electric distribution of the bushing; partial discharge meets the requirement of IEC standards

            ² LSR sheds with special shape design provides strong environment adaptability

            ² Good dynamic thermal stability and control over temperature rise

            ² Excellent mechanical properties and outer insulation performance

            ² Excellent anti-seismic performance

            Product application:
             
            After the completion of 1100kV type test in 2009, all type tests of some products have been completed successively. The 1200kv GIS inlet and outlet bushing has been put into use in India's 1200kv test station in 2012.
