ANSI C29.9 - TR 222 - 25kV Class-95kV BIL, Cast Cycloaliphatic Epoxy Station Post Insulator, 10.0" Length, Outdoor Apparatus

Electro Composites SDC™ composite bushings are designed to provide the toughest, cleanest and safest bushing solution for all HV applications. We make standard OEM and aftermarket form-fit-function replacement bushings for substation transformers, GSU transformers, oil circuit breakers, switchgear, wall/floor (air-air and oil-oil), HVDC and other applications. Available from 1kV up to 170kV with current ratings up to 21,500A. SDC™ (Solid Dielectric Capacitor) bushigs have a one-piece cycloaliphatic epoxycore and integral sheds. All SDC bushings are solid dielectric insulation – oil–free construction, capacitance graded condenser core with internal CT pocket/ground shield and a flange test tap, available in bottom connected or draw-lead configurations. Made in accordance with the most current bushing standards: IEEE C57.19.01, CSA C88.1, IEC 60137.

  • Solid cast cycloaliphatic epoxy compound for optimal strength and outdoor service performance
  • Cast-in place stainless steel inserts
  • Designed per ANSI C29.9 (for Standard TR models)
  • Can be mounted upright or underhung
