Vitreous Enamel Variable Power Resistor Ceramic Tube Wirewound

Vitreous Enamel Ceramic Tube Wirewound Power Variable Resistors


Structure :

1.The resistor wire is made of iron chromium aluminum, nickel chromium wire or constantan wire ,with high temperature resistance, stable electrical performance and low temperature drift coefficient .
2.Ceramic Tube(aluminum content 75) used as the winding matrix, with high heat dissipation.
3.Surface Colour :enamel green.
4.Non-inductive & variable type on requests;
5.Working voltage and Nominal resistance value are related to Ohm’s law.


Features:

1.Fixed type or Variable type are available.

2.The surface layer is enamel,with firm structure,strong pollution resistance,chemical gas erosion resistance,high insulation,moisture resistance & high temperature resistance,used in harsh environments.
3.High power,shock resistance,fast heat dissipation,high stability,long life & good moisture resistance.
4.Taps/Termianls leading out for bolts/wire connection.
5.Support precision resistance tolerance requirement.
