Brand:

Electro Composites

Catalog ID:

250-008-T-954-00

SDC™ 52kV-800DL A Transformer Condenser Bushing, Solid-Dielectric-Capacitor Type, Rated per IEC 60137, Drawlead Connected for Air-to-Oil Applications, 12.75" Min. Oil Immersion Level/CT Pocket Length, 56.8" Min. Creepage Length

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.

  • 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 IEC 60137 Electrical and Mechanical Requirements
