18L0009WH GE DCS protective surge capacitor

The GE 18L0009WH is a 138kV protective surge capacitor designed to safeguard medium-voltage rotating machines and transformers from transient overvoltages. Featuring a film-foil dielectric system with non-PCB insulating liquid and sealed bushings, it reduces the steepness of voltage wavefronts to provide turn-to-turn insulation protection for large motors, generators, and switchgear. This unit supports both indoor and outdoor applications and can be installed in vertical or horizontal positions for flexible integration into power systems.
