The GGD type AC low-voltage distribution cabinet is a technical progress development project issued by the Ministry of Energy in 1990 with the aim of promoting the technological progress of the low-voltage distribution industry in our country and accelerating the replacement and upgrading of low-voltage distribution complete switchgear. It was designed and developed by the Low-Voltage Complete Switchgear Joint Design and Research Group of the Ministry of Energy (referred to as NLS), and was successfully passed the ministerial-level appraisal hosted by the Ministry of Energy in October 1992. It has now been widely applied throughout the country.
