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
