Brand: Electro Composites

Catalog ID: 350-020-T-721-00

SDC™ 69kV 2000A Transformer Bushing, Bottom connected for Air to Oil application, 21in ground shield, 117.6in creep, rated per IEEE C57.19.01

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) bushings 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.

  • SDC™ - Solid Dielectric Capacitance Graded Composite Construction
  • EC-APG-02 Cycloaliphatic Epoxy Compound for Optimal Performance
  • No oil, paper or porcelain
  • Can be mounted vertically or horizontally
  • Meets IEEE C57.19.01 Electrical and Mechanical Requirements
