Rongxin solid state switch 10KV~35KV is developed by completely new principle and technology. It has the merits of resistance to high voltage, large current, high surge- resistant capability, large turn-off current and short turn-off time, etc. With stable performance and long life time, our large current solid state switch 10KV~35KV is widely used in modern power system so as to achieve quick, accurate and flexible control of the power system. In addition, it solves the technical difficulty of cutting large current within short time by breaking any short-circuit current that is above 60kA within 10-20ms. Therefore, Rongxin large current solid state switch 10KV~35KV emerges as one of the ideal high power switching devices, filling the blank in the industry.

Rongxin has independently developed its own medium, low voltage solid state switch SSTS which is below 35kV. The solid state switch is able to solve the problems existent in traditional mechanical switches and completely replace current spare power automatic switching devices. That is because it has greatly increased the switch speed and service life, which ensure that the sensitive load is free from abnormal power supply. In this way, the solid state switch is capable of ensuring normal operation of equipment, extending life time of equipment, increasing working efficiency, and thus infectively brings down the economical loss caused by power quality problems.

The fault current limiter (FCL) is suitable for power systems of different voltages between 400V to 500kV and can be applied in system interconnection, bus section, personal power source connection with public utility grid, and parallel connection with reactors to protect generators and transformers, etc.
