1000W Corrugated High Power WireWound Resistor Ceramic Tube For Inverter

1000W Corrugated Ceramic Tube High Power Wirewound Resistors for Inverter


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.Different assembly & fitting available;

3.Single unit with multi-resistance/ Multi-terminals also available;

4.Non-inductive & variable type on requests;

5.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 ;


Applications:

Widely used in frequency converter,elevator,hoisting,ship,electric power,welding,power supply,military industry,aviation,wind power generation,solar power generation,generator test load,automation equipment,railway system and other industries .
