The wire-wound resistor of the resistance box of the JRA heating pipe adopts stainless steel pipe as the wrap  which has a good looking appearance. The resistor has the characteristics of weather resistance, vibration  resistance, fast heat dissipation, high level of protection, etc. Its security is superior to traditional resistors  of porcelain skeleton. The resistor is a power type wirewound resistor packaged with the basic materials of  high temperature-resistant silicone resin and silica fume. Easy to install tightly and easy to attach heat sink.  Usable as a braking resistor to protect the inverters, servos, etc., from damage by regenerative energy of the  motor, and as a resistive load in power electronic load tests.
