Adjustable Ceramic Tube Power Wirewound Resistor Variable Type

Adjustable Ceramic Tube Power Wirewound Resistor ,Variable Type


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. These resistors are suitable as loading resistor,braking resistor,capacitor discharge,resistive load simulation,machinery,machinery and equipment higher power application.
2. Mounting fixture is available.
3. Resistance adjustable version :DSR series .
4. Resistance box and load bank available with power up to 2000kW.
5. Support precision resistance tolerance requirement.
