Product Description

 
Product Description
Wirewound Resistor
Wirewound resistor is made by fixing two leading-out terminals on the cylindrical ceramic tube which is coiled by bandlet and wave shape alloy resistance wire. The surface of the ceramic tube is coated by layer of fireproof coating which is resistant to flaming and high temperature. As the framework of the resistance wire. The ceramic tube can also work as the radiator.This product can be made to order .

Application 
Widely used as load resistor, power dissipation device and brake resistor in the field of Power Grid, Elevator, Crane, Shipbuilding, Frequency Inverter, UPS ect. 
It is suitable for simulated load test, the discharging of equipment, automatic control and the dynamic braking of the transducer.
