         TNR series decoupling device installed in tandem with rated voltage 500V and below power supply mortgage slightly system, used to increase the length of the wire wire inductance, make up for the lack of coordination, coordination of different specifications of surge protector zhijian. A surge protector typically used in B and C levels is installed in a distribution box. The length of the line to the next level the lightning arrester lightning arrester Zhijian is less than 10m, between the two lightning protection device should be equipped with decoupling device. As the decoupler is in series in line, the corresponding decoupler should be selected according to the load current of the line.

          The decoupler has excellent inductance characteristics for instantaneous high-energy lightning current and ensures the reliable action of the surge protector when the lightning overvoltage comes.
