Description
It is a new product self-designed and self-developed by introducing oversea advanced techniques and the requirements of rural and urban power network reform. The core parts are load switch, switch-fuse combinations or circuit breaker.
Application
It is applicable to the ring network or terminal power supply system with three-phase AC 50Hz, rated voltage of 12kV, rated current of up to 630A. It is widely used in the load center powder distribution station of urban residential area, high-rise building, large public buildings, factories and enterprises as power receiving and distribution or overload protection, short circuit protection; As a ring network power supply unit and terminal equipment, it plays role in the power distribution, power controlling and electrical equipment protection, so it is widely installed in prefabricated substations.
Normal operating conditions
