Brand: Electro Composites
Catalog ID: 150-075-G-882-00
SDCâ„¢ 25kV-7500A GSU Transformer Condenser Bushing, Solid-Dielectric-Capacitor Type, Rated per IEEE C57.19.01, Bottom Connected for Air-to-Oil Applications, 19.8" Min.Oil Immersion Level/CT Pocket, 37.0" 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) 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.
