High Power Tubular Fixed Wire wound Resistors Mounted on Frames

High Power Tubular Fixed Wirewound Resistors Mounted on Frames


Structure :

1.The inner high temperature resistance ceramic tube is used as the resistance matrix,is wound with chrominum alloy wire ,then coated with high temperature & non-flammable resin for protection to let resistors with better appearance and heat dissipation effect,after natural drying,baking at different temperatures before assembly.

2.Ideal electronic component to be assembled inside high-power load bank for testing for flexible installation mode.


Features:

1.In different applications,called ceramic wirewound resistors,ceramic tuberesistors,high power resistors,ripple resistors,braking resistors,charge resistor,discharge resistors,dump load resistors,current limiting resistors,aging resistors or load resistors,ect.

2.High power,shock resistance,fast heat dissipation,high stability,long life & fast delivery .

3.Taps/Termianls leading out for bolts/wire connection,solder,screw or fast-on terminals.
