Product Overview
GTXGN □ -12/630 is a solid composite insulated ring main unit switch used in medium voltage distribution networks. In the same power supply unit, three-phase A, B, and C are composed of three independent modules, which can provide several combinations for the distribution network. Composite insulation has load switches, circuit breakers, and multiple operation functions such as manual and electric. By selecting intelligent controllers such as FTU and other related equipment, it can achieve different degrees of control, measurement, and protection functions.
The equipment combination is flexible, and users can configure and control optional devices in stages according to different investment stages, with strong upgrade ability and investment savings. The operating mechanism of composite insulation load switches and circuit breakers is a combination of independent quick closing and quick opening manual operating mechanisms and mechanically driven motor closing/opening operating mechanisms. The electric operating mechanism of the load switch releases energy directly from the electric energy storage and closes, thus maintaining the same simplicity and reliability as the manual mechanism in any situation.
