Detailed Product Description

Round Shape High Power Cement Coated Wirewound Brake Resistors

High Power Round Shape Cement Coated Wirewound Brake Resistors

 

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,different styles of mounting brackets

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

4.Non-inductive & variable type on requests;

5.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.
