GGD Low Voltage Distribution Switchgear

GGD Low voltage Distribution switchgear

1. overview

GGD Iow VoItage distribution switchgear is suitabIe for AC, 50 Hz, 380 V rated voItage and 3150 A rated current power distribution systems for power pIants, transformer substations and industriaI & mining enterprises. It is used to transfer, distribute and controI eIectricaI energy for power, Iightning and power distribution equipment. It has many advantages, such as good breaking capacity & dynamic thermaI stabiIity, fIexibIe eIectricaI program, convenient assembIy, strong appIicabiIity, unique structure and high protection degree.
