High Power Ceramic Tube Wirewound Resistor For Aging Testing
Structure :
1.The 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.The High Power Wirewound Resistor Series includes DDR&DQR(wave-shaped alloy ribbon)&DSR(variable wirewound ).They are called ceramic wirewound resistor,ceramic tube resistor,high power resistor,waved resistor,braking resistor,charge resistor,discharge resistor,dump load resistor,current limiting resistor,aging resistor or load resistor,ect.
3.Working voltage and Nominal resistance value are related to Ohm’s law.
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.
