Product details
■ Product Overview
The XGN15-12 Box-type Fixed AC Metal-Enclosed Switchgear (hereinafter referred to as the Ring Main Unit) is a new type of high-voltage electrical product designed and developed by us by introducing overseas advanced technology and in accordance with the requirements of domestic rural and urban grid transformation. All technical performance indicators fully comply with the IEC62271-200:2003 and GB3906 standards.
The main switch, operating mechanism, and components of the Ring Main Unit adopt ABB original parts or imported parts assembled domestically into SFL-12/24 type switchgear, or can be equipped with ABB original HAD/US type SF6 circuit breakers or VD4-S type vacuum circuit breakers according to user needs. Its operating mode is divided into manual and electric.
The cabinet body is formed by processing on a CNC machine tool and then riveted, with a protection class of IP3X, and features reliable mechanical interlocking and anti-misoperation functions. This product has the advantages of small volume, light weight, beautiful appearance, simple operation, long service life, high parameters, no pollution, and low maintenance.
The XGN15-12 Box-type Fixed AC Metal-Enclosed Switchgear is suitable for AC 50Hz, 12kV power networks for the reception and distribution of electric energy. The main switch in the cabinet is an SF6 switch.
