          Two invention patents from the China Xidian Group, one of China's key power appliance manufacturers, recently won national patent gold awards.

          One of the two patents is the high current carrying capability interrupter for a high-voltage switchgear, which is mainly used to solve the problem of circuit breaker flow capacity, and the products of the patent are widely used for 1100Kv voltage power transmission lines.

          The other patent is the inner shield railway digital signal cable which is used for railway signaling automatic block systems and station coded information transmission.

          Over the years, Xidian has always adhered to independent innovation and intellectual property creation, and so far has more than 1,300 patents, of which more than 160 are invention patents with advanced technology from China and the world.
