300W Enamelled High Power Tubular Wirewound Braking Resistors

 

Structure 

1.A tubular ceramic has two terminals,and is wound with copper wire or chrominum alloy wire to provide the resistance,then the surface coated with high temperature glaze.After the semi-finished resistor cool and dry,insulation is applied through a temperature process and then the mounts are attached.If made into wave-type,not only eliminate the parasitic inductance of the resistor,but also improve the heat dissipation.

2.The tubular core is of special ceramic,capable of withstanding high thermal shock and overload of short duration.

3.Surface Colour:enamel green.

4.The tubular core is of special ceramic,capable of withstanding high thermal shock and overload of short duration.

 

Features

1.Fixed or Variable Type are available.The surface layer is enamel,with firm structure,strong pollution resistance,chemical gas erosion resistance,high insulation,moisture resistance & high temperature resistance,used in harshenvironments.
2.Surface glazed,won't be easily polluted or eroded by chemistry gas,high insulating capacity,canresist humidity and heat well,can be used in the atrocious environment.
3.Small size,high power rating,good overload and heat durability capacity,the useful time is longer than the others.
4.High power,shock resistance,fast heat dissipation,high stability,long life & good moisture resistance.
5.Taps/Termianls leading out for bolts/wire connection ;
6.Widely used for PCB installation,DC circuits,and low frequency AC circuits.
